▼ This dissertation examines the iconographical motif of the Apollonian triad in Attic art of the sixth and fifth centuries BC. Attic vase paintings constitute the chief evidence for this study, but other evidence, such as inscriptions, literary sources, sculptures and coins is considered, as well. My thesis focus on scenes without a clear mythological context, where the triad appears alone or accompanied by other, mostly, divine figures, and on what messages or information these images of the Apollonian triad convey. This study contributes to the ongoing discussion of the iconography and iconology of Attic vases, which enriches our understanding of Athenian socio-political and religious life and of Greek culture, more generally.

▼ Carbohydrates have numerous roles in plants, serving as photosynthetic precursors required for growth, respirable substrates, osmoregulators, and sometimes, as osmoprotectants. Additionally, carbohydrates can act as cellular signals, controlling gene expression. In experiments with cut Helianthus, Lilium, and Rosa, we explored the effects of endogenous and exogenous carbohydrates on
vase life and ethylene sensitivity.
Cut Rosa produced in South America are shipped for thousands of miles, frequently stored prior to shipment, and are held dry during shipping and storage. To see if protective carbohydrates would prevent or aid recovery from dehydration stress associated with dry shipping and storage, we conducted a number of pulsing and
vase solution experiments with carbohydrates not currently used as pulsing and
vase solutions. In cut Rosa ‘Freedom’, treatment with protective carbohydrates such as polyols, trehalose, and raffinose as
vase solutions frequently resulted in a
vase life similar to that of stems treated with sucrose, which averaged 14.6 and 15.7 days. The longest
vase life for stems treated with protective carbohydrates was 13.9 and 15.5 days for one Splenda® and raffinose concentration, respectively.
Vase life of water treated stems for these experiments was 13.2 and 13.9 days. In a subsequent experiment, no increase in
vase life above the water control was observed for Splenda® or for either component of Splenda®, maltodextrin or sucralose, while sucrose yielded an increased
vase life. The monosaccharides glucose and fructose yielded
vase life as good as, or better than,
vase life of stems treated with sucrose. Fructose increased
vase life by as much as 4.4 days over sucrose; a commercial preservative solution increased
vase life by 4.5 days over sucrose. When sucrose, glucose, and fructose were used as
vase solutions, glucose and fructose contents of petals sampled on day 6 were the same in all cases, ranging from 31.83-34.96 and 67.03-69.86 mg∙g-1 dry weight for glucose and fructose, respectively. In contrast, glucose and fructose contents were decreased in water-treated roses (21.52 and 44.19 mg∙g-1 dry weight, respectively). In two experiments using carbohydrates as pulsing solutions prior to shipping, and in a third experiment using carbohydrates as holding solutions prior to storage, no increase in
vase life above the water control was noted for any carbohydrate solution for Rosa ‘Freedom’, ‘Judy’, ‘Polo’, ‘Verdi’, or ‘Versilia’, although
vase life differed by cultivar. Pulsing with solutions of abscisic acid, ascorbic acid, giberellic acid, indole-acetic acid or quercetin did not yield noticeable changes in
vase life in cut Rosa ‘Charlotte’ or ‘Freedom’; however, these pulses may have influenced carbohydrate content.
Some reports suggest Lilium species are not sensitive to ethylene, while other reports indicate otherwise. A previous report indicated that ‘Stargazer’ had increased sensitivity to ethylene after cold storage. We hypothesized…

▼ The primary objective of this research was to identify practices by which specialty cut flower growers can extend the
vase life of cut delphinium, sunflower, and dahlia. Experiments investigated the effects of nitrogen fertilization rate on delphinium 'Guardian Mix' and the effects of deficit irrigation on delphinium 'Guardian Blue.' 'Guardian Mix' plants produced marketable cut stems at nitrogen rates as low as 50 mg/L. Deficit irrigation did not change
vase life, stomatal conductance, or transpiration rates of delphinium 'Guardian Blue.' Studies tested the effects of foliar calcium applications or benzyladenine application on sunflower 'Moulin Rouge' and 'Procut Lemon.' Calcium did not change the
vase life, stomatal conductance, or transpiration rates of either sunflower cultivar. Benzyladenine applied as a preharvest spray or a postharvest dip did not alter
vase life of sunflower 'Moulin Rouge' or 'Procut Lemon.' Transpiration rate and conductance rates of sunflowers significantly decreased in the first three days after harvest. In both sunflower experiments,
vase life of 'Moulin Rouge' was shorter than
vase life of 'Procut Lemon.' Benzyladenine was also applied to dahlia 'Park Princess' and 'Karma Yin Yang' cut flowers. Benzyladenine did not change dahlia
vase life. Dahlia 'Park Princess,' 'Bride to Be,' 'Cherish,' and 'Lollipop' cut flowers were not sensitive to exogenous ethylene. Further experiments tested the effect of flower stage at harvest,
vase water temperature, or preharvest fungicide application on dahlia 'Park Princess' and 'Karma Yin Yang' cut flowers.
Vase life of 'Park Princess' flowers was extended when flowers were harvested before fully open, but 'Park Princess' flowers harvested at budbreak failed to open completely after harvest. 'Karma Yin Yang' cut flower
vase life did not differ when flowers were harvested at different stages. Placing cut dahlias in hot
vase water had varied effects, but did not extend
vase life of either cultivar. Fungicide applications extended
vase life of 'Park Princess' flowers. However, the use of fungicide is not necessary to prevent postharvest fungal infection in cut dahlias. The results of all experiments indicate that optimal handling practices vary between cut flower taxa and that factors determining cut flower
vase life are complex.

▼ This study was aimed at exploring data analysis techniques for generating accurate estimates of the loss in quality of fresh fruits, vegetables and cut flowers in chilled supply chains based on data from advanced sensors. It was motivated by the recent interest in the application of advanced sensors, by emerging concepts in quality controlled logistics, and by the desire to minimise quality losses during transport and storage of the produce. Cut roses were used in this work although the findings will also be applicable to other produce. The literature has reported that whilst temperature was considered to be the most critical post-harvest factor, others such as growing conditions could also be important in the senescence of cut roses. Kinetic modelling was the most commonly used modelling approach for shelf life predictions of foods and perishable produce, but not for estimating vase life (VL) of cut flowers, and so this was explored in this work along with multiple linear regression (MLR) and partial least squares (PLS). As the senescence of cut roses is not fully understood, kinetic modelling could not be implemented directly. Consequently, a novel technique, called Kinetic Linear System (KLS), was developed based on kinetic modelling principles. Simulation studies of shelf life predictions for tomatoes, mushrooms, seasoned soybean sprouts, cooked shrimps and other seafood products showed that the KLS models could effectively replace the kinetic ones. With respect to VL predictions KLS, PLS and MLR were investigated for data analysis from an in-house experiment with cut roses from Cookes Rose Farm (Jersey). The analysis concluded that when the initial and final VLs were available for model calibration, effective estimates of the post-harvest loss in VL of cut roses could be obtained using the post-harvest temperature. Otherwise, when the initial VLs were not available, such effective estimates could not be obtained. Moreover, pre-harvest conditions were shown to correlate with the VL loss but the correlation was too weak to produce or improve an effective estimate of the loss. The results showed that KLS performance was the best while PLS one could be acceptable; but MLR performance was not adequate. In another experiment, boxes of cut roses were transported from a Kenyan farm to a UK distribution centre. Using KLS and PLS techniques, the analysis showed that the growing temperature could be used to obtain effective estimates of the VLs at the farm, at the distribution centre and also the in-transit loss. Further, using post-harvest temperature would lead to a smaller error for the VL at the distribution centre and the VL loss. Nevertheless, the estimates of the VL loss may not be useful practically due to the excessive relative prediction error. Overall, although PLS had a slightly smaller prediction error, KLS worked effectively in many cases where PLS failed, it could handle constraints while PLS could not.In conclusion, KLS and PLS can be used to generate effective estimates of the post-harvest VL loss of cut…

▼ Cut 'Freedom', 'Charlotte' and 'Classy' rose stems were subjected to various pH and EC solutions created by adding NaCl, Na2SO4, or CaCl2 to various base solutions: Floralife Professional; distilled water; or solutions of HCl, H2SO4, NaCl, Na2SO4, or NaOH. It was determined that the ideal laboratory solution has a low pH, 3.5 to 4.0, and an EC of 1.0 dS•⁻¹. The best salt to add is Na2SO4, but all tested salts provided acceptable results. The average
vase life of cut Rosa stems placed in a 1.0 dS•⁻¹
vase solution was 13.9 d and the minimum, 5 d, was recorded for a 'Freedom' rose in either distilled water or a H2SO4 solution.
Low pH solutions partially counteracted the negative effects of a high EC, but did not result in the longest
vase life for the study. When
vase life is plotted against EC, distilled water has a slope of -1.71, while HCl and H2SO4 have slopes of -0.84 and -0.21, respectively. The flatter slope of the acidic solutions indicates that the
vase life of stems placed in a low pH solution did not decrease as EC increased as drastically as stems placed in water of a higher pH.
In preliminary temperature studies, when using a standard mercury thermometer, 11, 13, or 14 h were required for a quarter, half, or full size box, respectively, to warm up from 3 to 23.8°C and twice as long for the same boxes to cool to 3°C. However, during a fluctuating temperature study using temperature data loggers, a half size box only required 4 h to warm up and 8.5 to 9 h to cool down. In a variable temperature study, the longest
vase life, 15.3 d, was obtained when 'Freedom' stems remained in a 1°C cooler for 48 h, while the shortest
vase life, 11.5 d, occurred when stems remained in a 20°C environment for 48 h. In a constant storage study, the longest
vase life, 11.7 d, was obtained when 'Freedom' stems were placed in a 1°C cooler for 12 h.
Vase life decreased linearly with both time and temperature to 6.4 d at 30°C for 36 h. 'Charlotte' stems also had the longest
vase life, 8.6 d, at 1°C for 12 h, and shortest of 2.9 d at 30°C for 36 h. 'Classy' stems had the longest
vase life, 9.3 d, at 1°C for 24 h, and shortest, 5.8 d, when held at 30°C for 48 h.
In a National Cut Flower Trial Program, stems of promising cultivars were pretreated with either a commercial hydrating solution or DI water and placed in either a commercial holding solution or DI water. Over six years, the
vase life of 88 cultivars representing 38 cut flower genera were tested. While there was cultivar variation within each genera, patterns of postharvest responses have emerged. The largest category, with 35 cultivars, were those that responded positively to a holding preservative; these cultivars were in the genera Acidanthera, Adenophora, Antirrhinum, Campanula, Capsicum, Celosia, Dianthus, Digitalis, Echinacea, Eustoma, Helianthus, Heptacodium, Heuchera, Leucanthemum, Lobelia, Physostegia, Rudbeckia, and Trachelium.

▼ The papers compiled in this thesis comprise a series of successively executed investigations into the role of micro-organisms in xylem plugging, and disturbance of the water relations and the
vase life of cut flowers. For this purpose
Rosahybrida cultivar 'Sonia' (the hybrid tea-rose
Rosa cultivar 'Sweet Promise') was selected. Chapter 1 comprises an introduction into the economic importance of cut flowers and the capability of cut flowers for post harvest
life. In addition, a brief review is given of literature on physiological and microbiological factors which can influence the
vase life of cut flowers. Gaps in our knowledge of the mechanisms leading to vascular blockage of cut flowers are discussed. An outline is given of: (1) the selection of a greenhouse
Rosa cultivar as plant material to study, (2) the experimental methods applied, (3) the results of preliminary investigations, and (4) the microbiological factors investigated. Chapter 2 shows that stems of freshly cut flowers contain a wide variety and low numbers of microbial species. The initial microbial load on stems of
Rosa flowers was found to be much lower than those on
Chrysanthemum and
Gerbera stems. Their distribution on the flower stem is not homogeneous. The stem flora, predominantly
Enterobacter ,
Bacillus and fungal species, lost its dominance in the
vase fluid. The
vase water showed an initial predominance of
Pseudomonas species which do not require organic growth factors. In the course of the
vase life Enterobacter and
Bacillus species became dominant. These bacterial genera require organic nutrients and special growth factors for their multiplication. Fungal growth was shown at a later stage, mainly in
vase fluids of
Chrysanthemum and
Gerbera flowers, which have a much longer
vase life and a higher initial number of fungi on their stems than
Rosa flower stems. Chapters 3, 4 and 5 demonstrate that the extent of infiltration of viable microbial cells into the xylem vessel system of
Rosa and
Gerbera cut flowers depends upon the number of microbial cells per ml initially added to the
vase fluid, the shape and the size of the individual microbial cells and the width of the xylem vessels. Scanning Electron Microscopic (SEM) observations as well as the assessment of the number of bacteria Infiltrated into
Rosa xylem vessels showed in addition that: (1) the number of bacteria which infiltrated into xylem vessels increased with time and, (2) this number increased with increasing numbers of bacteria initially added to the
vase fluid, (3) this number decreased with increasing distance between cutting point and sampling point, (4) only a minor part of the bacterial and fungal cells suspended in the
vase fluid was able to infiltrate into the xylem vessels of the flowers, a major part of the microbial cells remained attached to the cut surface, (5) even low numbers of infiltrated…

▼ Studies were conducted to determine the effects of preharvest humidity and water stress levels during production on cut Lilium L. and Helianthus L. stems and various postharvest procedures on cut Rosa hybrida L., Helianthus L., and Zinnia Jacq. stems. Subjecting Lilium ‘Dazzle’ and ‘Vermeer’ stems to high humidity during production did not reduce cut flower
vase life but increased stem length and production time. In Helianthus,
vase life, water uptake, stem length, stem diameter, and head diameter of cut ‘Sunbright’ stems were positively correlated with production time in high humidity. Applying water stress to ‘Dazzle’, ‘Vermeer’, and ‘Sunbright’ during production did not affect
vase life at the treatment level; however, water potential readings during the last five days before harvest were negatively correlated with
vase life in ‘Vermeer’, and water potential readings from up to 36 days before harvest were positively correlated with
vase life in ‘Sunbright’. Bud number in ‘Vermeer’ was positively correlated with stem diameter, and stem diameter in ‘Dazzle’ and ‘Vermeer’ was reduced as soil moisture deficit increased. Quality of cut ‘Sunbright’ stems was reduced as soil moisture deficit increased.
Vase life in cut ‘Vermeer’ and ‘Sunbright’ stems was negatively correlated with the change in fresh weight in both humidity and water stress preharvest experiments.
Postharvest studies determined that R. hybrida
vase life was influenced by cultivar and
vase solution, where commercial preservative solutions resulted in longer
vase lives and smaller changes in fresh weight than the controls, but also less water uptake. Exogenous ethylene did not affect
vase life but decreased water uptake. Application of the anti-ethylene agent silver thiosulfate (STS) significantly improved
vase life in a majority of the rose cultivars tested, but 1-methylcycloprepene (1-MCP) did not improve
vase life over the control. Both
vase life and water uptake were reduced when more than one stem was placed in a
vase, where placing ten stems in a
vase decreased
vase life by 1.4 days and water uptake by up to 10.6 mL/stem/day. Leaving stems dry before placing in vases reduced
vase life, but recutting immediately before placing in vases minimized the decline. Rose stems responded positively to increasing the amount of stem removed, where cutting from 1 to 15 cm off the end improved
vase life.
Drying stems of Helianthus ‘Sunbright’ for up to 48 hours did not significantly reduce
vase life when stems were recut after drying time; however,
vase life was affected by storage temperature such that the longest
vase life of 13.2 days occurred when stems were stored for 3 days at 5°C. Placing more sunflower stems in a
vase did not statistically affect
vase life.
Vase life of cut Zinnia ‘Benary Giant Deep Red’ stems was reduced when…

▼ Cut flowers show a wide variance of keepability. The market demands more and more a guaranteed quality. Therefore, methods must be developed to predict
vase life of cut flowers. Chrysanthemum (
Dendranthema x grandiflorum Tzvelev) and some other cut flowers suffer from unpredicted early leaf wilting during
vase life. Researchers from Wageningen University and from the Research Station for Floriculture and Glasshouse Vegetables started a joint project to investigate the problem of early leaf wilting and to come to a better prediction of
vase life of cut flowers. Preliminary experiments pointed out that early leaf wilting is caused by a decrease of the water uptake due to embolisms that are induced at the cut surface. This thesis reflects a part of the project on early leaf wilting and is focussed on the anatomical aspects of the stem water transport system. Chrysanthemums are propagated by stem cuttings, which grow in about 12 weeks to commercial maturity. Flowering is induced by a short day treatment. Cut chrysanthemums have an erect stem and the leaves are helically arranged along the stem. The primary vessel bundle network was elucidated, revealing that leaves have their direct water supply from different vascular bundles, which are positioned around nearly half of the circumference of the stem (2.1). The xylem water transport system consists of primary xylem and secondary xylem. The older the stem part (i.e. the lower in the stem) the higher the relative amount of secondary tissue. Digital image analysis procedures were constructed to enable the quantification of large amounts of anatomical data. Xylem vessel characteristics along the chrysanthemum stems were thus quantified and a mathematical description of the vessel characteristics was developed (2.2). Hydraulic conductivity, amount of vessels, average diameter of vessels, and vessel length all showed a gradual exponential decrease from the base to higher up the stem. The hydraulic resistivity calculated from vessel lumina was 30% lower than the experimentally measured resistivity, irrespective of the position in the stem. The remaining 30% is at least partly caused by the resistance of the intervessel pits. A new theory was developed to explain the regulation of vessel lengths in plants (2.3). Vessel length depends on the amount of fused tracheary elements. The only assumption in the theory is that each element has the same chance to be the end of the vessel during vessel formation. This results in an exponential vessel length distribution, which indeed is always found in our chrysanthemum stems. The plant can thus determine its vessel length distribution by just steering the chance factor. This theory provides the most simple mechanism that enables plants to regulate the length of xylem vessels. Stochastic regulation of biological processes might be widely present in nature. We reviewed and refined a method to obtain flat planes in all desired directions through frozen hydrated (biological) specimens (Chapter 3). A…

▼ Restriction of leaf water loss, by stomatal closure, is decisive for plant survival, especially under conditions of water deficit. This sensitivity of stomata to low water potential is attenuated by high relative air humidity (RH ≥ 85%) during growth, which impedes the plant’s ability to survive when subsequently exposed to lower humidities due to a negative water balance. This thesis focuses on the extent of the existing variation and the reasons underlying cultivar differences in their tolerance to high RH, as well as the rate and reversibility of stomatal adaptation to elevated RH in the course of leaf ontogeny. Cut rose was used as a model plant. An experiment on the postharvest water relations of three contrasting cultivars in their sensitivity to high RH showed that the sensitive cultivar (i.e. steepest decrease in the cut flower longevity) underwent a higher increase in the water loss compared to the tolerant cultivars. Preventing vascular occlusion considerably extended the time to wilting in the sensitive cultivar grown at high RH, showing that the high rate of water loss, as a result of plant growth at high RH, can only be detrimental for keeping quality under limiting water uptake conditions. Further investigation showed a large genotypic variation in the regulation of water loss, as a result of leaf development at high RH, and stomatal closing capacity was the key element in this process. The degree to which the stomatal anatomical features were affected and the extent that their functionality was impaired were not correlated. However, higher stomatal density, longer pore length and depth contributed to the higher water loss of high RH-grown leaves (16–30% of the effect depending on the cultivar). Reciprocal change in RH showed that stomatal functioning was no longer affected by the RH level after full leaf expansion. However, expanding leaves were always able to partly adapt to the new RH level. For leaves that started expanding at high RH but completed their expansion after transfer to moderate RH, the earlier this switch took place the better the regulation of leaf water loss. This behaviour of expanding leaves experiencing a shift from high to moderate RH was related with the increasing population of stomata exceeding a critical stomatal length. Contrary to this, leaves initially expanding at moderate RH and transferred to high RH exhibited poor stomatal functioning, even when this transfer occurred very late during leaf expansion. This suggests that stomata at various developmental stages were similarly prone to loss of closing ability, when these had been exposed to high RH prior to full leaf expansion.
