▼ Interspecific hybridisation is potentially a very useful tool for tree breeders, particularly as a source of variation for important genetic traits. However, hybrids in several tree species have been shown to be highly susceptible to damage by some pests. Therefore, the primary aim of this study was to determine if hybrids in Eucalyptus were more susceptible to pests than pure species. To achieve this, the responses of a number of vertebrate, invertebrate and fungal pests to hybrid eucalypts and their parent species, were examined in several experimental field trials and in a natural hybrid zone. Firstly, susceptibility of hybrids to the fungal leaf disease caused by Mycosphaerella spp. was examined in an experimental field trial, including first generation (F1) hybrids and controlled crosses of E. globulus and E. nitens. Both the host preference and genetic variation in resistance were investigated. Heritabilites were low to moderate and disease severity was greatest on the F1 hybrids. Hybrids were more susceptible to damage by Mycosphaerella than both E. globulus and E. nitens. Secondly, the host species preference and hybrid susceptibility was examined for chrysomelid leaf beetles (Chrysophtharta spp. and Paropsis spp.), the gum leaf skeletoniser (Uraba lugens) and for brush tail possums (Trichosurus vulpecula) in a number of experimental hybrid trials. Heritability estimates were very low for possum damage on E. globulus, and high for E. nitens. The proportion of dominance variation for possum damage was consistantly higher than heritability estimates in E. globulus, and at least as high as heritability estimates in E. nitens. E. morrisbyi and E. gunnii consistently had the most possum damage and E. globulus, E. nitens and E. johnstonii the least. Responses of the pest species to the different hosts and hybrids varied but hybrids were generally intermediate in their susceptibility to the different herbivores when compared with their parent species. Thirdly, this thesis examines the host species preference of a number of insect taxa and the host susceptibility of E. amygdalina, E. risdonii and E. amygdalina x E. risdonii hybrids. In a previous study by Whitham et al. (1995) in a natural hybrid zone, hybrids were found to be more susceptible to both insect and fungal taxa than either E. amygdalina or E. risdonii . The genetic basis of this observed hybrid susceptibility was examined by determining the distribution of a number of insect taxa in an experimental field trial, where the pedigree of the majority of hybrids and pure species was known. Species richness was found to be greater on hybrids than pure parent species. Furthermore, F1 eucalypt hybrids tended to be more susceptible to attack than advanced generation hybrids, arguing against hybrid breakdown being the cause of the greater susceptibility of the hybrids. Mechanisms contributing to the observed responses on the E. amygdalina x E. risdonii hybrids were also examined. Leaf…

▼ This thesis covers the construction of genetic linkage maps of two Eucalyptus globulus parental trees (chapter 2), the detection of quantitative trait loci (QTL) carried out using these linkage maps (chapter 3) and a genetic analysis of rooting ability of micropropagated cuttings from two E. globulus families (chapter 4). Genetic linkage maps of two parent trees were constructed using 326 RAPD and 21 microsatellite markers. At a LOD score threshold of 4.9 for grouping and 3.0 for marker ordering, the male parent had 13 linkage groups consisting of 101 framework markers and the female parent had 11 linkage groups with 97 framework markers. Even though both parents originated from the same provenance it was found that polymorphic RAPD markers were readily detectable. Linkages between microsatellites previously reported for E. grandis/E. urophylla were conserved in the E. globulus cross. Segregation distortion of markers was found to be more prevalent than expected by chance. The linkage maps were used to detect QTLs based on 155 progeny grown in field trials. Twelve traits were included in the QTL analysis. These included: wood density (Pilodyn penetration), extent of early flowering (bud abundance), and growth (height at years one and two, stem diameter at years two, three, four and six, and relative incremental growth between years one and two, two and four, and four and six). Using interval mapping a total of eight QTL with LOD score peaks over 2.0 were detected, corresponding to seven map intervals. QTL detected included: two for cumulative growth; two for wood density; one for early flowering and three for relative incremental growth. Since the 155 progeny trees were grown at seven trial sites, an analysis of marker by site interaction was carried out with more marker by site interactions being found than expected by chance. Markers with significant QTL effects were examined for interaction with site with both of the cumulative growth QTL found to have significant site interaction. QTL stability with age was also analysed for these QTL, and both growth QTL were found to have a detectable association with the first measurements of height and diameter. A study of the rooting ability of cuttings grown in tissue culture from two families of E. globulus was undertaken with the aim of detecting QTLs for this trait. The two families were found to have significantly different rooting abilities indicating that genetic variation for the trait was present. Estimates of variance components relating to genetic and environmental effects indicated that within both families the variance due to genetic effects was small compared to the environmental variance with clonal repeatabilities of 0.17 and 0.14 for the two families. These estimates were used in power calculations based on t-tests of single markers under some simple assumptions. However even under optimistic circumstances the power for QTL detection was found to be too low to warrant the time and expense of genotyping required for…

▼ In eucalypts, inbreeding may occur under open-pollination (OP) or when effective population sizes are reduced by intensive selection. Breeding strategies employing inbreeding have also been suggested. This Thesis examines inbreeding in three widespread and commercially important temperate eucalypts: Eucalyptus globulus, E. nitens and E. regnans. Inbreeding depression was severe for growth traits in all species. Flowering was also depressed in E. nitens, whereas pilodyn penetration and relative bark thickness were unaffected. In a long term E. regnans study, the survival of inbred progenies was significantly lower than outcrosses. However, the mortality of selfs obscured an increase in inbreeding depression with age for growth traits. In most traits examined, inbreeding depression was associated with levels of quantitative dominance, however, some traits exhibited inbreeding depression but no dominance, suggesting the action of rare alleles with major effect. Inbred progenies were virtually absent from OP families from closed native E. globulus forests, however, outcrossing rates were lower in families from isolated parents. Biparental inbreeding may also be important under OP in native stands, as mating nearest neighbour depressed growth equivalent to half-sib inbreeding. However, the selection against selfs observed in E. regnans, suggested most inbreds are eliminated by reproductive maturity thereby reducing the level of inbreeding in natural populations and the ability to purge genetic load. The fitness of parents under OP did not appear to be related to additive differences but may be correlated with outcrossing rate. However, it is argued that mixed mating is evolutionary stable, favoured by the reproductive ecology of the species. Heritabilities estimated from OPs were greatly inflated compared to heritabilities estimated from outcross progenies in E. regnans and E. nitens, particularly for traits that exhibited inbreeding depression. A reduction in outcrossing rate from 1.0 to 0.8 in E. globulus was associated with lower breeding value estimates, suggesting variability among families in outcrossing rates may inflate heritabilities estimates and bias breeding values. In the E. regnans study, inflated heritabilities and additive variances estimated from OPs approximated outcross parameters as inbreds were selected against. However, OP heritabilities were also reduced as stand development enhanced of variation within OP families. In addition, OPs overestimated age-age correlations and poorly predicted outcross performance. Mixed model methods were developed to account for dominance and inbreeding, and were applied to self and outcross progenies of E. regnans. Ignoring inbreeding depression biased breeding values for diameter, but dominance was unimportant. Accounting for rare deleterious alleles improved the model, however, breeding values predicted under a simple model were almost perfectly correlated with those under a…

▼ The optimum age for early selection of eucalypts in breeding to minimise the total cost of producing kraft pulp was investigated. The effect of future changes in density and pulp yield on the cost of converting roundwood to unbleached kraft pulp was modelled by defining cost functions for each stage of the kraft pulping process. The pulping cost function was combined with cost functions for growing, harvesting, and transporting plantation-grown eucalypt wood to derive a production function for the total cost of kraft pulp production in relation to the biological traits of growth rate, stem form, basic density and pulp yield. The economic value of trait improvement was combined with assumed genetic parameters to determine expected gain towards the objective for a given breeding effort in each trait. Density and growth were shown to be the most important traits for breeding, followed by pulp yield and stem form, with relative values of 3.6, 3.2, 1.9 and 1 respectively. Breeding to improve only density and growth was demonstrated to achieve 95% of the gain possible from breeding for all four traits. Pith-to-bark density profiles were determined for 588, 7-year-old plantation grown Eucalyptus nitens trees. Results were aggregated to derive age-age correlations for density which were shown to be high. Age-age correlations for growth were determined across a greater sample using height measured at 20 months and diameter at 1.3 m measured at four years and seven years. Based upon dual trait selection for density and growth, the optimum economic age for early selection, the selection age where the present value of all future gains is maximised, was determined to be three years. The optimum biological selection age, the selection age where average annual gain is maximised, was determined to be four years. Assessing wood properties is expensive and time consuming, reducing considerably the use of these traits in selection programs. The thesis demonstrated the application of the Pilodyn in the indirect selection of density in E. nitens, with very high genetic correlation (rg=-0.92) between Pilodyn penetration and density. The application Near Infrared Reflectance Analysis (NIRA) in the indirect selection of pulp yield was explored, however problems with calibration left results inconclusive. This thesis clearly points to an increasing emphasis on wood properties, in particular wood density, in selection decisions and to a reduction in selection age to as early as three years of age. Such practices are expected to impact significantly on the overall costs of producing eucalypt kraft pulp in Australia.

▼ Eucalyptus nitens is an important species in plantation forests in Tasmania and is becoming important in other cool temperate regions of the world. Reliable initiation of roots in cuttings is needed, to enhance forest productivity through the establishment of clonal plantations. Adventitious root initiation is dependent on the re-polarisation of cells to form a new root meristem. Failure to initiate roots may be due to the inability of the plant to undergo re-polarisation of cells to form a new meristem. The research undertaken has been directed at the manipulation of some of the factors that are implicated in the establishment of cellular polarity in plants. Several new techniques for enhancing root initiation have been investigated and shown to promote root formation in cuttings of E. nitens. The principle conclusions of the research are outlined below. It was demonstrated that a high proportion of E. nitens seedlings have the ability to initiate adventitious roots in cuttings collected from very young seedlings. This ability is lost quickly as the plant ages. The loss of rooting ability does not appear to be related to any specific changes in the stem morphology. Histological examination demonstrated that the loss of rooting ability is not correlated with the formation of structural barriers within the stem or callus. Root primordium formation appears to occur in regions of undifferentiated callus in most cuttings but can also occur directly from the cambium, with little or no intervening callus phase. Root initiation was found to be sensitive to the timing and method of auxin applications. It was possible to increase the proportion of cuttings that initiate roots by delaying the application of auxin until several weeks after the cuttings were first placed on the mist-bed. Calcium ions are part of the mechanism by which auxin signals are translated into cellular actions. Attempts to increase the rate of root initiation in cuttings by altering calcium levels in the surrounding medium were inconclusive. Electric potential differences are known to play a role in the establishment of cellular polarity and in organogenesis from callus. It was demonstrated that low voltage electric currents could be used to stimulate root initiation in some cuttings. It was hypothesised that cuttings with substantial basal callus would be most receptive to this treatment, but this was found not to be the case. The experiments using electric currents were difficult to replicate and were subject to unexplained variation in results. Further development of the technique is required to quantify the effects of such currents and to identify the mode of action. Stigmasterol and vitamin D were demonstrated to act as auxin synergists in the promotion of root initiation in cuttings and also to stimulate the growth of tissue cultures. ATPase extracts were prepared to investigate whether the action of sterol potentiation of auxin is associated with changes in membrane bound I-1+-ATPase activity. The…

▼ Eucalyptus nitens is a hardwood plantation species used in cool-temperate regions of the world. It is mainly used for pulp and paper, although there is increasing interest in using this species for producing high quality appearance and structural timber products. Therefore breeding programs need to consider the requirements of different markets and breed for a variety of end-uses. The aim of this thesis is to study the genetic control of E. nitens wood properties. The focus is on three different product groupings which are pulp and paper, appearance grade timber, and structural grade timber. Pulp and paper traits studied were wood density, cellulose content, fibre length and fibre coarseness; appearance grade timber traits were collapse, checking and decay; and structural grade timber traits were stiffness and microfibril angle. Genetic parameters and potential genetic gains were estimated using data from 12 year old E. nitens progeny trials grown on three sites. Wood properties were sampled using 12 mm cores taken at a height of approximately 1 metre. Relationships between whole tree wood density and core wood density, and whole tree pulp yield and core cellulose content were investigated. For both traits core samples were good predictors of whole tree values. Methods were developed to assess wood collapse and decay using wood cores. All wood properties except fibre coarseness had significant genetic variation, with heritabilities ranging from 0.38 to 0.56. The heritability for stem diameter was 0.39. Genetic correlations between traits were mostly significant and reasonably high. Adverse correlations occurred between diameter and density, diameter and collapse, diameter and stiffness, and between density and cellulose. Favourable correlations occurred between diameter and cellulose, density and collapse and between density and stiffness. Genotype by environment interactions were sometimes present but were always small. Genetic selection can significantly improve the quality of wood produced for pulp and paper, appearance grade timber and structural grade timber. Of particular importance are the potential gains in collapse (or checking) and stiffness, where genetic selection can potentially lift the quality grades of appearance and structural products. Selecting a deployment population for high decay resistance may minimise the risk of value loss on sites known to have severe decay problems. Breeding goals for all product groupings are reasonably well correlated and improved product quality can be achieved in all product groupings without the need for specialised breeds. Selecting for wood density, as well as growth rate, is a minimum requirement if high grades of timber are to be produced.

▼ Eucalyptus urophylla is one of the most extensively used forest tree species in plantation forestry worldwide. Commonly, E. urophylla is used in hybrid combinations with species possessing better wood properties largely because it is an exceptional grower and it imparts good disease resistance. E. urophylla is endemic to islands of the Lesser Sunda archipelago situated north of Australia. Human induced deforestation practices including urbanization are threatening the existence of several natural populations of the species throughout its range. It has become crucial that efforts be made to conserve the genetic resources in this species. To this end, a forest tree conservation genetics organization called Camcore (http://www.camcore.org) in collaboration with other forestry institutions has initiated seed collection explorations throughout the Lesser Sunda archipelago. Collected seed was sown in provenance test trials to gather information including growth performance of different genotypes in exotic locations. Comprehensive species-wide genetic diversity surveys (at the gene and genome levels) will assist in determining the genetic relationships between different E. urophylla populations, information that is relevant for guiding in situ and ex situ conservation strategies for the species. Nucleotide diversity studies exploit the diversity between homologous gene sequences from different individuals to identify the genetic variation underlying phenotypic traits. Commonly, genetic variation is in the form of single nucleotide polymorphisms (SNPs). Information on SNP diversity coupled with a detailed understanding of the molecular evolution of candidate genes including linkage disequilibrium (LD), selection and recombination may lead to the identification of haplotypes (a combination of SNPs that are inherited together) that associate with trait variation. Thus, sequence diversity surveys in candidate wood biosynthetic genes in E. urophylla may lead to the identification of allelic (SNP) haplotypes that associate with wood quality traits.

▼ Eucalyptus urophylla is one of the most extensively used forest tree species in plantation forestry worldwide. Commonly, E. urophylla is used in hybrid combinations with species possessing better wood properties largely because it is an exceptional grower and it imparts good disease resistance. E. urophylla is endemic to islands of the Lesser Sunda archipelago situated north of Australia. Human induced deforestation practices including urbanization are threatening the existence of several natural populations of the species throughout its range. It has become crucial that efforts be made to conserve the genetic resources in this species. To this end, a forest tree conservation genetics organization called Camcore (http://www.camcore.org) in collaboration with other forestry institutions has initiated seed collection explorations throughout the Lesser Sunda archipelago. Collected seed was sown in provenance test trials to gather information including growth performance of different genotypes in exotic locations. Comprehensive species-wide genetic diversity surveys (at the gene and genome levels) will assist in determining the genetic relationships between different E. urophylla populations, information that is relevant for guiding in situ and ex situ conservation strategies for the species. Nucleotide diversity studies exploit the diversity between homologous gene sequences from different individuals to identify the genetic variation underlying phenotypic traits. Commonly, genetic variation is in the form of single nucleotide polymorphisms (SNPs). Information on SNP diversity coupled with a detailed understanding of the molecular evolution of candidate genes including linkage disequilibrium (LD), selection and recombination may lead to the identification of haplotypes (a combination of SNPs that are inherited together) that associate with trait variation. Thus, sequence diversity surveys in candidate wood biosynthetic genes in E. urophylla may lead to the identification of allelic (SNP) haplotypes that associate with wood quality traits. Such haplotypes will be very valuable in Eucalyptus breeding programmes. The aim of the current M.Sc. study was to investigate levels of nucleotide and allelic (SNP) diversity in three candidate wood biosynthetic genes of E. urophylla. Levels of nucleotide diversity were surveyed in two cellulose biosynthetic genes, namely, cellulose synthase 1 (CesA1) and sucrose synthase 1 (SuSy1) , and the lignin biosynthetic gene cinnamyl alcohol dehydrogenase 2 (CAD2) of E. urophylla.

▼ Decay arising from pruning wounds in plantation-grown Eucalyptus spp. is a concern for the Australian solid wood products industry, as the potential for decay spread within the tree is unknown at present. Mechanisms of antimicrobial defence in the xylem of Eucalyptus nitens were investigated. Key factors investigated within the host-fungal interaction included phenolics, moisture content, mineral content and anatomical alterations (tyloses and suberization). A purple reaction zone was regularly observed at the sapwood interface of decay lesions developing from naturally-infected pruning wounds in plantation-grown E. nitens. Total phenols levels were increased substantially and vessel tyloses were abundant in the reaction zone. A log incubation experiment showed that after 9 months the reaction zone remained intact while sapwood became decayed. The reaction zone was significantly drier than healthy sapwood, with lower levels of potassium, and a lower pH than both sapwood and heartwood. These trends are more similar to conifer reaction zones than deciduous angiosperms. The mode of reaction zone defence appears to be a dynamic process (also similar to conifers) rather than a static process typical of deciduous angiosperms. The initial stages of antimicrobial defence formation were also studied. Xylem defence responses occurring in young pot-grown E. nitens saplings were analysed within the first few weeks following stem wounding and inoculation with the decay fungus Ganoderma adspersum (which displayed relatively slow colonization of the wounded xylem). Events occurring most quickly after wounding and inoculation were tylose formation and phenol accumulation, which indicates that they are key defences. NMR imaging revealed that changes in xylem moisture content were not rapid after wounding. Reaction zone extracts were inhibitory to test-fungi in thin-layer chromatography bioassays. Analysis of extracts by liquid chromatography — electrospray ionization mass spectrometry revealed that a diverse range of hydrolyzable tannins were present in E. nitens wood, including over thirty gallotannins, ellagitannins and phenols. A number of ellagitannins (particularly pedunculagin) were considerably more abundant in the reaction zone than the healthy sapwood and may contribute to the effectiveness of the reaction zone as an antimicrobial barrier. The process of reaction zone formation may be an accentuation of processes that occur when heartwood forms. Heartwood extracts were qualitatively similar to reaction zone extracts but actual increases in ellagitannins were not as great. Conditions such as season of wounding and the type of fungi which become established in wounds, appear to effect the degree of defence response. This was indicated by phenol levels. More extensive decay lesions were generally associated with more phenolic production. Sterile inoculations and weakly-aggressive fungi were associated with no or little reaction zone formation, while aggressive fungi elicited more …

▼ Low nitrogen availability commonly limits the growth of Eucalyptus miens (Deane and Maiden) Maiden plantations in south-eastern Australia. However, until this study was undertaken little was known of the nitrogen uptake and assimilation processes of temperate eucalypt species like E. nitens. In this study ammonium and nitrate uptake by young roots of solution cultured E. nitens were characterised under a variety of conditions using two different techniques: net uptake on a macro scale measured as depletion from solution, and net fluxes on a micro scale estimated from measurements of concentration gradients near root surfaces using microelectrodes. Datasets taken from the literature were used to both validate the use of the depletion method for nitrogen, and to find the most appropriate method to use for the estimation of kinetic parameters from depletion datasets. Ammonium and nitrate depletion from solution was characterised with respect to nitrogen source, pH, temperature, and N status. Ammonium uptake rates were consistently higher than nitrate uptake rates in all experiments. Uptake rates for both ammonium and nitrate were higher at pH 4 than at pH 6, and they were reduced to a similar extent with a decrease in temperature from 20°C to 10°C (Q10 values of 1.3 to 1.9). For ammonium uptake, there was evidence for rapid adaptation of uptake processes (within 24 hrs) to changing temperature. Nitrogen status, which was correlated with relative growth rate (RGR), had unclear effects on uptake characteristics and highlighted deficiencies of measuring uptake by long term (up to 10 hours) nutrient depletion. Ion selective electrodes were used in the MIFE (microelectrode ion flux estimation) technique to simultaneously measure ammonium, nitrate, and proton fluxes within the unstirred layer surrounding roots of E. nitens in solution culture. Measurements were within the region 20 to 50 mm from the tip of primary roots approximately 80 mm long. Within this region fluxes of ammonium, nitrate, and protons varied little, spatially or temporally. Under these conditions there was a consistent flux stoichiometry for ammonium: nitrate: and protons of 3.1: 1: -6.0. When ammonium and nitrate concentrations were both set at 100 µM there was no inhibition of nitrate uptake by ammonium, but at concentrations of ammonium and nitrate in the range 200-1000 µM there was an apparent suppression of nitrate uptake. There was evidence for two mechanisms of ammonium uptake. The mechanism at low concentrations (<200 µM) showed saturation kinetics with a K m of 15 µM whereas at high concentrations (200-1000µM) an approximately linear increase in uptake occurred. Excision of the shoot brought about a rapid and dramatic reduction in fluxes of ammonium, nitrate, and protons. The apparent preference shown here for ammonium over nitrate could be indicative of an adaptation by E. nitens to grow in cold, acidic, forest soils where ammonium is more readily available than nitrate. These results suggest that nitrogen…

▼ Studies on vegetation and insect predation were conducted during the period 1982-84 at the Ridgeway Park Reserve, Tasmania. The vegetation of the area is eucalypt forest and woodland which varies in composition, dominance and structure. Soil type, topography, the level of grazing and incidence of fire also vary within the study area. The influence of soil type on moisture availability was investigated by comparing the vegetation on sites receiving the same incident solar radiation. The majority of species experience a shift in distribution over the three soil types such that with increasing radiation the species reach their peak frequency first on the brown earth, then on the podzolic soil and finally on the podsol. This pattern conformed to a model of moisture availability devised for the three soils. Species that did not conform to the model were either particularly vulnerable to the effects of grazing or fire, opportunists or restricted to one or other of the three soil types and hence a particular set of soil nutrient conditions. The effects of insect grazing on sapling eucalypts on north and south-facing slopes, which differed in geology, were assessed by monthly monitoring of insect damage and by deterring insects from grazing certain trees through the use of insecticide. On every tree percentage damage, and the amount of different types of damage, leaf loss, mean shoot length, the number of leaves per shoot and the percentage of damaged leaves, were measured on the current season's shoots. A limited sample of the same data was collected on leaves approximately one year old. Overall, there were few significant differences in the level of these variables between the different species and sites. Percentage damage figures were comparatively low (7-12%) and there was no significant difference between the species. However, damage was significantly higher in the most mesic, least fertile site. Percentage damage, and leaf and shoot loss were combined to derive a figure for the total damage to each species (29-41%). This was significantly higher in E. obliqua compared with the other species. The patterns of insect defoliation may have been considerably altered as a result of a drought experienced during the course of the study. Insect activities may effect forest community composition, but only as part of a web of inter-relationships whose effects vary, between the species, in space and time.

▼ This thesis studies quantitative genetic variation in the forest tree, Eucalyptus globulus. It examines the effects of inbreeding and hybridisation on fitness, as well as genetic variation in breeding traits using an extensive base population and a diallel of intra- and inter-race reciprocal crosses. Marked post-zygotic barriers to hybridisation occurred between E. globulus and E. ovata, with F1 hybrids exhibiting high field mortality. Inbreeding similarly had deleterious effects, but by 10 years F1 survival was less than the selfs. Relative hybrid fitness is dependent on inbreeding levels of parental population. Open-pollinated (OP) progenies also exhibited growth depression compared with outcrosses, clearly indicating significant inbreeding is occurring under this mating system. Genetic variation was examined in a base population of E. globulus established on four sites in Argentina. This population included OP progenies from native stands and land races. Thirty variables were studied, representing growth, bark thickness, form, transition to adult foliage and Pilodyn penetration, and used to determine population affinities. Significant genetic differentiation occurred between populations in most traits. Land races had closer affinities to native stands from southern Tasmania. Many native populations were superior in growth to land races, but land races had better form. Significant genetic variation was also detected within E. globulus populations. Heritabilities were low for forking, survival and form; intermediate for growth and bark thickness; and high for Pilodyn penetration and transition to adult foliage. There was strong positive genetic correlation between the same trait measured at different sites and ages. Growth traits were genetically independent from other key breeding traits. Genetic parameter estimates from OP progenies may be biased by inbreeding depression, as well as specific combining (SCA), maternal and carry-over effects. The effects of such factors on growth were examined using a diallel mating amongst eight trees from two E. globulus races. Rapid germination and large seeds resulted in larger seedlings in the nursery, but these carry-over effects disappeared after two-years field growth at two Tasmanian sites. Additive and SCA effects were insignificant at this age, but the interaction between males and females was significant, with reciprocal inter-race hybrids differing in performance. Parents differed in chloroplast haplotypes and this is the first evidence for cyto-nuclear interactions affecting growth of a eucalypt species. Such reciprocal effects could bias genetic parameters and mean the cross direction may be important to maximise gains from mass controlled pollinated seed production systems being developed.

▼ Chemical characters in the majority of the Tasmanian species of Eucalypts have been investigated to determine their value to the taxonomy of the genus. The investigation has included three classes of chemicals. 1. The leaf and twig bark anthocyanins of each of twenty-two species were isolated and identified; it was found that anthocyanin distribution generally paralleled the split of the Tasmanian Eucalypts into two sections, namely, Sections Macrantherae and Renantherae. Cyanidin compounds containing glucose are the most widespread in the genus, other anthocyanidins found being delphinidin, malvidin and peonidin. The anthocyanin pattern of the Macrantherae is generally simple, and is based on the 3-glucoside and 3,5-diglucoside of cyanidin. The Section Renantherae, is further subdivided into two groups on the basis of the distribution both of the galactosides of cyanidin and delphinidin and of the methylated anthocyanins ~ this division parallels that based on morphological characters. The anthocyanin patterns of some renantherous species, (E. coccifera, E. risdoni and E. tasmanica) reflects the simplicity of the patterns found in macrantherous species. 2. Other flavonoids in leaf and twig bark were classified according to their Rf values in different solvent systems. Certain aglycones and alcohol-soluble polyphenols were restricted to either section or to groups within these sections. Again, these divisions agreed with morphological classification excepting for E. coccifera. 3. Protein and isoenzyme patterns of seedlings of the twenty-two species were obtained. Peroxidase and esterase patterns were useful in showing taxa relationships. All macrantherous species, except E. aggregata showed similar peroxidase patterns, while E. aggregata showed a typically renantherous pattern. Quantitative differences in peroxidase bands reflect intra-section variation. Qualitative and quantitative variations in esterase patterns also provide useful taxonomic markers in the two sections. Chemical characters were also used in an investigation of the E. viminalis/E. dalrympleana complex in Tasmania. Macro-molecular characters of seedlings did not aid in distinguishing the two species, but differences in the phenolic compounds of the seedling leaves enabled positive identification of a "viminalis-type" or a "dalrympleana-type" tree.

▼ In order to evaluate the range of stem canker fungi in natural eucalypt forest and plantations in Tasmania, a systematic survey was conducted. A total of 210 samples representing 30 fungal species were collected. The three species most frequently encountered were Endothia gyrosa, Cytospora eucalypticola and Valsa ceratosperma. Ten of the fungal species detailed in this survey were newly published and five were reported for the first time in Australia. Pathogenicity studies were conducted with 11 fungal species collected from the survey. Three species (E. gyrosa, Phoma sp. and Seiridium eucalypti) could cause significant cankers on both E. nitens and E. globulus. Influences by host species, provenance, age, vigour and bark type on canker development are discussed. The incidence of canker is higher in rough-barked E. nitens compared to smooth-barked trees. Longitudinal cracking in rough bark provides natural infection courts. However, once infected artificially, smooth-barked E. nitens is more susceptible than rough-barked. This susceptibility is attributed to the anatomical structure of smooth bark facilitating post-infection penetration. A high incidence of severe E. gyrosa cankers was observed in 1993 at Tewkesbury (northwestem Tasmania) within a vigorously growing plantation of mixed (smooth or rough barked) provenances of 16 yr old E. nitens. This observation initiated an in-depth investigation of E. gyrosa. Stem inoculations with isolates of E. gyrosa originating from different locations across Australia showed that all can infect E. nitens and E. globulus. However, isolates from Tasmania, Victoria and Western Australia were generally more aggressive than those from the Australian Capital Territory and New South Wales. Endothia gyrosa isolates from Australia and overseas were compared. Four main types of colony morphology were recognised among 133 isolates based on the colour and density of the vegetative mycelium. Vegetative incompatibility was detected using a pH amended medium. Sixteen isolates from different origins in Australia, South Africa, North America and Europe were grouped into 9 vegetative compatibility groups with this method. There was correspondence between the grouping of these sixteen isolates as determined by colony morphology and vegetative compatibility and those revealed by DNA polymorphisms in RFLP and RAPD analyses. Overseas and Australian isolates appear closely related. Within Australia isolates from as geographically distant locations as Western Australia and Victoria were grouped together. The significance of observed levels of intraspecific variation in E. gyrosa is discussed. The potential threat of canker fungi, especially E. gyrosa, to the plantation forestry is reviewed.

▼ This project examined silvicultural and environment factors which affect precocious and abundant flowering in trees of the economically important plantation species Eucalyptus nitens with the aim of optimising seed production. Two separate studies were undertaken to examine how flowering and seed quality were affected by the macroenvironment. The first studied an altitudinal gradient which would span the range where operational seed orchards might be located. Flowering abundance and seed production was greatest on sites where growth rate was highest. Seed weight, germination success and germination rate decreased as site altitude increased. The second study examined the effects of water availability. Flowering abundance was highest in trees experiencing water stress, whilst seed quality remained unaffected by parental water status. Overall, the maternal tree had a greater influence on seed quality traits than the environmental effects studied. On the microenvironmental scale, the effect of tree spacing on flower abundance and capsule survival was studied at two sites where trees were 5 and 13 years old. As the spacing between trees increased so too did reproductive yield, not only per tree but also per hectare. Furthermore, it appears that as trees mature, tree density needs to be decreased to maintain the maximum reproductive yield per hectare. To overcome the strong genetic control of flowering precocity a hormone manipulation approach was tested. The gibberellin biosynthesis inhibitors paclobutrazol, chlormequat chloride and prohexadione were applied to seedlings and their relative effects compared. These treatments reduced both growth rate and endogenous levels of GA1 to varying degrees, with paclobutrazol the most effective. However, none of the treatments promoted precocious flowering. Further environmental and/or chemical manipulation would be required to induce precocious flowering in E. nitens seedlings. The application of nitrogen fertiliser to juvenile trees stimulated precocious and abundant flowering. This was due in part to accelerated growth rate but nitrogen also acted independently of growth rate. In contrast, phosphorus had no effect on growth or reproductive output but did cause trees to undertake vegetative phase change earlier. Nitrogen fertiliser combined with hormone manipulation with paclobutrazol was applied to juvenile and mature plantation grown trees to promote precocious and abundant flowering. There was an additive effect in combining the treatments in promoting both precocious and abundant flowering. The production of pedigree seed traditionally required three visits to the mother tree to carry out controlled pollination. To improve the efficiency of this process, a number of novel controlled pollination procedures were tested on both E. nitens and E. globulus. A new single visit pollination protocol for E. globulus was successfully developed, whilst the techniques applied to E. nitens yielded no advantage over the traditional method. This new…

▼ Genetic differentiation at the site level was investigated within Eucalyptus obliqua L'Herit., by comparing the progeny of phenotypically distinct populations from adjacent sites along ecological gradients. Seed was collected from 12 maternal trees within each of four sites in south-east Tasmania. The Forestier sites comprised a topographic sequence of a wet sclerophyll forest type within a moist gully (Gully population) adjoining an open, dry sclerophyll forest type along an exposed ridge (Ridge population). The Lune sites formed a sequence of a wet sclerophyll forest type from the mid-slope position of a broad ridge system (Mid population) adjoining an open woodland from the lower slopes and plain (Plain population). Studies of the progeny from each of the 48 maternal trees were undertaken in various laboratory experiments and in planting trials established within each of the four sites. The results provided evidence of genetic differentiation between and within the populations from the Forestier and Lune sites. Within the Lune populations, significant differences between progeny from the Mid and Plain were demonstrated for a number of attributes. The Mid population had higher germination energy, larger cotyledons, faster growth to age five years and lower susceptibility to leaf spotting fungi than the Plain population. Progeny from the Plain had higher frost resistance, higher persistence of coppice and a lower susceptibility of coppice shoots to browsing by native mammals. Within the Forestier populations, there were no differences between progeny from the Gully and Ridge for factors such as growth to age five years, leaf morphology, frost resistance or coppicing ability. However, significant differences were demonstrated for a range of other attributes. The Gully population had higher germination energy, lower production of lignotubers and lower susceptibility to infection by leaf spotting fungi and browsing by native mammals than the Ridge population. Many of the differences between adjacent populations could be regarded as evidence of adaptation to environmental factors operating at the local site level. The results indicated that differential selection forces may result in genetic differences between populations of E. obliqua over the scale of hundreds of metres, in addition to the tens or hundreds of kilometres normally associated with broad geographic variation at the ecotypic or provenance level. Variation at the site level has implications for the conservation of genetic diversity and for the probability of successful regeneration and long term adaptation and growth across heterogeneous sites within native forests.

O Brasil é um dos maiores produtores de polpa de eucalipto e suas plantações são dependentes do enraizamento adventício de genótipos selecionados. Neste trabalho foram analisados os efeitos de diferentes fontes de carboidratos e de qualidade de luz no enraizamento adventício in vitro de duas espécies de eucalipto economicamente importantes, Eucalyptus grandis, de fácil enraizamento e Eucalyptus globulus, recalcitrante ao enraizamento. As fontes de carboidratos testadas em meio de cultura líquido foram sacarose, glicose e frutose. Microestacas de ambas as espécies e plantas-matrizes de Eucalyptus globulus foram expostas a comprimentos de onda enriquecidos para luz branca, azul, vermelha e vermelho-extrema e seus efeitos foram testados em relação ao enraizamento. O enraizamento adventício aumentou em ambas as espécies quando foi fornecida sacarose durante a fase de indução e frutose na fase de formação. Fazendo uma analogia entre o enraizamento adventício e a tuberização de batata, este resultado pode ser atribuído a atividade de invertases na fase de indução e fructoquinase na fase de formação, porém mais estudos devem ser conduzidos para confirmar esta hipótese. Não houve efeito de qualidade de luz no enraizamento adventício quando os tratamentos de luz foram aplicados nas microestacas. A exposição de plantas-matrizes crescidas em meio de cultura sem sacarose à ambiente enriquecido com comprimento de onda vermelho-extremo proporcionou um aumento de 255% na porcentagem de enraizamento de suas microestacas, mesmo na ausência de auxina exógena no meio de enraizamento, quando comparado com plantas-matrizes expostas à luz branca nas mesmas condições de cultura. Este resultado está aparentemente relacionado com o balanço 8 endógeno de açúcares solúveis e amido na parte aérea e raízes em desenvolvimento, com maior conteúdo de ambos na região das raízes.

Brazil is one of the largest producers of eucalypt pulp and its plantations are dependent of adventitious rooting of selected genotypes. In this work we analyzed the effects of different carbohydrate sources and light qualities on in vitro adventitious rooting of two economically important eucalypt species, the easy-to-root Eucalyptus grandis and the recalcitrant Eucalyptus globulus. The carbohydrate sources tested in static liquid medium were sucrose, glucose and fructose. The effect of white, blue, red and far-red light exposure on microcuttings of both species and on donor-plants of E. globulus was evaluated in relation to rooting. Rooting was improved in both species by supplying sucrose in the induction phase and fructose in the formation phase. By a putative analogy of adventitious rooting with tuberization in potato stems, this result was attributed to activities of invertases in the induction phase and fructokinase in the formation phase, but more studies will be needed to confirm this hypothesis. There was no effect of light quality on adventitious rooting when light treatments were applied on microcuttings. Compared to the white light-treated control…

▼ This project investigated the effect of waterlogging on the productivity of Eucalyptus globulus under field conditions, and the relative tolerance of the two temperate plantation eucalypt species, E. glob ulus and E. nitens, from the subgenus Symphyomyrtus, to waterlogging. In eucalypt plantations across Tasmania, waterlogging is a serious threat to productivity. It is estimated that at least 11 % of all commercial eucalypt plantations in Tasmania are affected to some degree, by waterlogging. The losses incurred by waterlogging during the first 2 years of plantation establishment were found to have significant long-term effects on tree productivity at two sites across the state. In the field, soil indicators of long-term waterlogging, specifically the evidence of greying, in combination with current seasonal waterlogging and development of hypoxic soil conditions were found to be the factors closely associated with severe reductions in tree height and growth. The use of extensive soil mapping and assessment prior to plantation establishment are therefore effective tools in identifying potential waterlogging problems. Under long-term waterlogging, there was no indication of the development of plant water stress during exposure to waterlogging. Waterlogged seedlings of both species exhibited reduced foliar nutrient status, with significantly reduced foliar nitrogen, phosphorus and potassium concentrations. Therefore, waterlogging-induced nutrient deficiency is a mechanism involved in the growth reduction of these species under waterlogged conditions. Various methods of fertiliser application were investigated to determine the most "effective mode in ameliorating waterlogging damage. Soil-based applications of slow release fertilisers applied either prior to, or after, a waterlogging event, were the most successful. Fertiliser application was associated with improved growth, foliar nutrition and increased aerenchymatous root production. Reduced availability of nutrients in waterlogged soils and/or reduced uptake of these nutrients are the two possible mechanisms leading to the development of foliar nutrient deficiency of waterlogged plants. It was found that under hypoxic hydroponic culture, seedlings with low nutrient status were capable of an increased uptake of nutrients when transferred to high nutrient conditions. This result is significant as it identifies reduced availability of soil nutrients as the primary mechanism responsible for the development of foliar nutrient deficiency in E. globulus and E. nitens under waterlogged conditions. The relationship between aerenchymatous root development and waterlogging tolerance was investigated. It was determined that singular measurements of root adaptive capacity should not be used as the sole measure of tolerance to waterlogging in these species. The regulation of growth and maintenance of relatively high photosynthetic rates are also useful indicators of tolerance. Using this array of measures, it was determined that E. nitens…

▼ A detailed investigation of the air flow through a timber stack with the flow both along and across the board is described. Measurements of velocity profile and turbulence level at various distances from the leading edge are presented to show the structure and development of the boundary layer flow under various free stream velocities. Existing theories on the laminar separation at entrance and the transition process from laminar to turbulent flow in the separated shear layer and the development of the boundary layer flow are examined and compared with experiments. Surface shear stress and friction factor are estimated from the measurement of the static head drop and boundary layer properties along the flow passage. These are used to predict heat and mass transfer coefficients with the Reynolds analogy between heat, mass and momentum transfers. A simplified model based on the concept of "free water" and "bound water" sharply separated by a fibre saturation point (FSP) is proved to be a useful concept for conveying preliminary idea but not sufficiently accurate for a detailed understanding of the drying of Tasmanian eucalypt timbers. Experimental evidence of surface temperature changes during drying and the formation of dry patches has led to an approach based on detailed measurements of the boundary layer flow and a coupled heat and mass transfer model within the boundary layer. In the model, the transfer of moisture within the wood is assumed to be a diffusion process in which the diffusion coefficient is independent of the moisture content and the driving force is the moisture concentration as in true molecular diffusion. The transfer of heat is modelled by considering the convective heat transfer over the board surface and the conduction heat transfer inside the board. The governing transport equations are solved numerically based on analytical solutions. The model has been validated by measuring moisture contents of slices of boards during drying. Successful drying of Tasmanian eucalypt timber from green to EMC with the test procedure outlined in the process of research is made for the quarter-sawn boards. The effect of edge drying on the overall drying behaviour of the whole board is shown and the analytic solution of the two dimensional diffusion equation is quoted. A literature survey on the mechano-sorptive effect is made as entry to the subject. Tests with the Tasmanian peppermint eucalypt timber are conducted under bending conditions and the stresses are applied in the direction across the grain. It is shown that nearly linear relationships could be fitted between the average moisture content and mechano-sorptive effect of the wood over the whole moisture content range, but the slope of the line changes at about FSP. The slope of the line also appears to be dependent upon the initial moisture content and temperature of the wood. It is also shown that change of the loading direction from along grain to across grain results in a large increase in the mechano-sorptive…

▼ A indústria de base florestal é estratégica para o Brasil devido ao seu perfil fortemente exportador. O setor responde pela segunda posição na balança comercial do agronegócio brasileiro, ficando atrás somente da soja em grão. Atualmente, a área ocupada com florestas de eucaliptos no Brasil atinge 1,9 milhões de ha. Diante da importância sócio-econômica que a silvicultura desempenha no mercado brasileiro e do aumento progressivo das áreas plantadas com florestas de Eucalyptus, o grande desafio para o melhoramento do eucalipto está na integração da biotecnologia mais avançada ao seu cultivo, o que compreende a identificação de genes controladores das características de importância econômica e ambiental e a transferência destes genes entre árvores por meio de cruzamentos controlados ou modificação direcionada. Portanto, os objetivos deste estudo foram apresentados em 3 capítulos distintos: I - a identificação de genes expressos em flores de E. grandis em processo de antese; II - o estudo mais refinado de mineração e identificação de genes potencialmente codificadores de fatores de transcrição presentes no genoma de E. grandis; e III - seleção de 50 genes cujas expressões mostraram-se constitutivas entre folhas e xilemas de E. grandis e xilema de E. globulus, pela técnica de hibridização de microarranjos de DNA. No capítulo I é apresentada uma breve fundamentação teórica sobre as flores de E. grandis e a importância do estudo da expressão gênica e da identificação de genes envolvidos em determinados processos metabólicos e fisiológicos das plantas. Nos resultados, apresentados juntamente com a discussão, estão apresentados o conjunto de transcritos identificados e a anotação dos mesmos conforme as bibliotecas geradas. As sequências de genes expressos estão fundamentalmente envolvidas na manutenção do órgão, na senescência e em respostas a estímulos ambientais. Também são mostrados resultados obtidos por RT-qPCR para genes selecionados a partir das anotações cujo perfil de transcrição foi avaliado para as partes da flor, folha e xilema. Ao final do capítulo, é feita uma breve descrição da metodologia e das conclusões referente a este estudo. A partir dos dados anotados dos genes expressos nas bibliotecas de flores e botões florais descritos no primeiro capítulo, foram encontradas algumas famílias de fatores de transcrição, dentre elas, a família Dof, encontrada nas bibliotecas de carpelos/receptáculos florais. Assim, um segundo capítulo foi redigido na forma de manuscrito de artigo científico a ser submetido ao periódico BMC Plant Biology, em língua inglesa. Após a fundamentação teórica sobre os fatores Dof em plantas, foram apresentados os resultados obtidos de um estudo mais refinado de mineração e identificação de genes potencialmente codificadores destes fatores de transcrição presentes no genoma de E. grandis. Posteriormente, uma quantificação dos níveis de mRNA para alguns dos genes Dof de E. grandis a partir da técnica de RT-qPCR foi realizada.

▼ Plasticizers are generally added to cosmetic and personal care products to improve the filmforming abilities of the product and increase flexibility of the film formed on the skin or hair surface. For example, plasticizers are present in perfumes to prolong the release of the specific scent, which is the ultimate goal in a good quality perfume. Plasticizers in nail varnishes prevent chipping, improve the aesthetics by adhering to the keratin in the nail which means the coating stays on for much longer, which is the ultimate goal in nail products. Plasticizers improve the gloss, resist chipping and allow quick drying time. Therefore it can be seen that plasticizers play a vital role in personal care products like perfumes and nail varnishes. Certain plasticizers e.g. phthalates, can cause problems associated with human health and can harm the environment. They are easily available and large volumes can be obtained at a low cost. These phthalates, for example, di-butyl phthalate (DBP) have been identified as carcinogenic. Nowadays the occurrence of cancer is rapidly increasing. The plasticizers present in a large number of consumer and personal care products, can possibly be linked to the ever increasing reports of cancer. Therefore a substitute to the traditional phthalate plasticizers must be investigated. The aim of this research is to produce a plasticizer derived from naturally occurring Eucalyptus oil, which can be used to replace the existing plasticizers in cosmetic formulations. Para-menthane-3,8-diol (PMD), occurring naturally in the oil from the tree, Eucalyptus citriodora, forms an acetal with citronellal (PMD, acetal, citronellal all occur naturally in the oil). It has been previously shown that PMD-citronellal acetal will exhibit plasticizing properties similar to conventional plasticizers. The objective was to enhance the formation of the acetal in the Eucalyptus oil by reacting it with excess PMD. An effective synthesis method for the PMD-citronellal acetal enriched oil (~73.8 percent) was determined from optimization experiments. The physical characterisation of the PMD-citronellal acetal enriched oil was done and compared with that of DBP. The acetal-enriched oil had a lower density, slightly higher solubility in water (at 25°C), lower refractive index (Brix percent) and a higher boiling point (350°C) than DBP. The physical characteristics of the Eucalyptus oil source and the acetal-enriched Eucalyptus oil were very similar. This can be expected as the Eucalyptus oil consists of ~84.3 percent Citronellal, ~ 1.3 percent PMD and 2.7 percent PMD-citronellal acetal. In this study the effectiveness of the acetal-enriched Eucalyptus oil (referred to from now on as the bio-plasticizer) was compared to a conventional plasticizer such as di-butyl phthalate (DBP), commonly used in cosmetic products. Two cosmetic formulations were produced: a nail varnish and a perfume formulation. Various tests were performed on these formulations to investigate the plasticizing properties of the bio-plasticizer. The objectives…

▼ This study was carried out at Entoto mountain Eucalyptus plantation, about 10 km north of the center of Addis Ababa, to assess the impact of Eucalyptus globulus Labill. plantation on the naturally regenerated woody species. Sixty plots of 400 m 2 (20 m X 20 m) size were established along a transect lines at every 300 m distance between them. Transects were laid in north–south directions at 500 m distance from each other. Seedlings, herbaceous species and soil samples were colleted from five sub-plots (4 m 2) within each major plot. A total of 68 plant species belonging to55 genera and 32 families were identified. Asteraceae (8 species) was the most dominant family. Out of a total of 68 plant species, 41 of them were naturally regenerated woody species recorded in Entoto E. globulus plantation. They represented 33 genera and 25 families. For the analysis of vegetation diversity, woody species density and soil environmental factors, the individual E. globulus plantation stands were used to classify the plots into three categories. These are C1 (plots with less than 154 E. globulus stands), C2 (plots consists of 154 to 199 E. globulus stands) and C3 (plots with greater than 199 E. globulus stands). Twenty plots were identified for each category. There was significance difference (P < 0.05) in the species diversity (H’) between C1 and C2, as well as C1 and C3 while there was no significant difference between C2 and C3. The species richness was also significantly different (P < 0.05) among the three categories of E. globulus plantations. The species diversity and species richness increased with the decrease in E. globulus plantation and vice versa. Sorenson similarity index showed highest similarity between C1 and C2 while C2 and C3 showed relatively weak similarity. The density of naturally regenerated woody species showed a decreasing trend with the increase in the density of E. globulus plantation and vice versa. Therefore, the density of E. globulus plantation was negatively correlated with density of naturally regenerated woody species. The study on vegetation and population structure showed that the density of tree species was high at the lower DBH class levels and there was good regeneration status. Density of naturally regenerated woody species greater than 2.5 cm DBH (cal.932.1 ha-1), height, frequency, basal area and the respective IVI values for naturally regenerated woody species were also calculated. There was no significant difference between the three categories of E. globulus plantations in their major soil nutrient contents. Advisors/Committee Members: Dr. Teshome Soromessa (advisor).
