▼ Peat moss is a major component of many
plant growing
substrates but is quickly becoming a limited resource. To reduce the reliance on peat moss a number of composted products, including pine mulch, manure, yard waste and aged bark - in combination with peat moss and/or coconut coir, were mixed in various combinations as growing
substrates for greenhouse potted Gerbera (Gerbera jamesonii) production. Four new
substrates were developed and compared to a commercial mix, BM6 in greenhouse production trials. Experiments were conducted to (1) compare the
plant growth and quality of potted Gerbera in the newly developed
substrates to BM6, (2) determine whether a pre-charge fertilizer was needed for the newly developed
substrates, (3) determine appropriate rates of a pre-charge fertilizer for the newly developed
substrates, and (4) determine the nitrogen drawdown index over the time of production and determine if there is a relationship between the NDI values and the nitrogen availability measured by pour through values. Two of the newly developed peat reduced
substrates were successful in producing acceptable quality potted Gerbera. One of the
substrates contained a low percentage of peat moss and the other contained coir fines. Fertilizer pre-charge rates, and some nutrient and irrigation management protocols were recommended for these two
substrates.

▼ Sphagnum peat moss is the most commonly used soilless substrate component to produce containerized greenhouse bedding plants. Perlite is often blended with peat to achieve desirable physical properties. Increasing transportation costs and occasional shortages of peat and perlite have increased the need for alternative substrate components. Wood fiber materials produced from the extensive secondary processing of pine wood chips are a potential partial alternative to peat and perlite. Incorporating wood materials into soilless
substrates may result in nitrogen immobilization, increasing the amount of fertilizer nitrogen needed during production. Wood materials also have a naturally higher pH compared to peat, requiring less limestone to adjust initial pH and leaving unknown effects on the substrate’s ability to buffer against pH changes. The objectives of this research were to evaluate the effects of wood fiber soilless
substrates on
plant performance, nitrogen requirements, and pH buffering capacity. Sphagnum peat-based
substrates amended with 30% (by volume) coconut coir, pine tree materials or a commercial wood fiber material were compared for their effects on
plant performance of container-grown petunia (Petunia × hybrida Mill.). There was a slight reduction in shoot growth of plants grown in pine tree
substrates and wood fiber compared to plants grown in peat alone; however,
plant performance was not significantly affected. In a second study, plants grown in
substrates made up of sphagnum peat:pine tree materials (50:50) or sphagnum peat and a commercial wood fiber product (50:50) were evaluated for their nitrogen requirements compared to a 100% sphagnum peat control. Plants grown in 50:50 peat wood fiber did not reach comparable growth to plants grown in peat alone, even when fertilized with increased (400-ppmN) nitrogen concentrations. Finally,
substrates made up of sphagnum peat and wood fiber (80:20, 60:40, 40:60, 20:80) were compared to
substrates made up of sphagnum peat alone and a peat and perlite control for effects on pH buffering and nutrient management with container-grown impatiens (Impatiens walleriana). This work shows the feasibility of amending soilless substrate with ~20-40% wood fiber (by volume) without drastic effects on
plant performance or the need to change any cultural practices. Results from this work show that surpassing ~40% incorporation rate affects
plant performance where it starts to suffer. This is potentially the result of physical properties, pH buffering or the presence of phytotoxic compounds present in the material.

ECOLOGICAL DISINFESTATION: PHYSICAL AND BIOLOGICAL CHARACTERIZATION OF FILTRATION SUBSTRATES FOR REMOVING ZOOSPORES OF PHYTOPHTHORA NICOTIANAE FROM WATER.

▼ Although recycling irrigation water is beneficial to the nursery industry as it serves to decrease potable water usage and reduces the release of excess agrichemicals into the environment, it also poses the risk of becoming the source for and means of dispersing water-borne
plant pathogens.
Plant pathogens of major concern in irrigation water are species of Phytophthora. These pathogens are a significant threat because they can attack a vast number of plants, many of which are ornamental crops grown in nurseries, by releasing motile zoospores directly into irrigation water. Several treatment methods are available to remove
plant pathogens from irrigation water; however, many of these methods are expensive, involve chemicals that are potentially toxic to plants, humans, and environment, and require frequent and time-consuming maintenance. Slow sand filtration is an ecologically based treatment system that only recently has been investigated for treatment of irrigation water at nurseries. Slow sand filtration can be fairly effective, but its application is limited because of the large surface area required and relatively slow flow rates that limit the volume of water treated in a set time period. The overall goal of this research was to examine four novel
substrates, in addition to sand, to determine if any could effectively filter zoospores of Phytophthora nicotianae from waters, with the potential to process large volumes of water, decrease maintenance required for slow sand filtration, or utilize faster flow rates while retaining filtration efficiency. The
substrates examined were sand, crushed brick, calcined clay, Kaldnes¨ medium, and polyethylene beads. My objectives were to characterize substrate physical parameters (uniformity coefficient and effective grain size), to determine substrate physical filtration capacity at six substrate depths (0, 5, 10, 20, 40, and 60 cm), to characterize the contribution of microbial components on filtration capacity – including the density of bacteria and dominant species of bacteria colonizing each substrate. Sand was the most effective physical filter and completely removed zoospores from water at depths of 40 and 60 cm. Sand also was the most uniform substrate and had the smallest effective grain size. Kaldnes¨ medium and polyethylene beads were the least effective
substrates at physically removing zoospores from water. When a microbial load was allowed to develop in the
substrates for 21 days, all
substrates removed significantly more zoospores than without a microbial load. Sand and calcined clay stimulated the highest density of microbial growth in the top 5 cm of the column. Sand was the most effective substrate when considering both physical and biological mechanisms for zoospore removal. Overall, sand remains the most effective filtration substrate for the removal of zoospores of P. nicotianae from water. Crushed brick and calcined clay were less effective but have the potential to be further optimized as alternative…

▼ For many years mining has been a vital component of the development of many countries. Although an important income generator, mining is one of the factors that affect biodiversity and ecosystems.There is an increase in the intensity of environmental damage caused by mining over the years, and thus an increased need to rehabilitate the disturbed ecosystems. The success of any rehabilitation project requires an ecological understanding of natural indigenous vegetation communities. This project investigated the potential use of mined substrates to establish indigenous savannah woody species. The main objective of this project was to investigate the establishment of indigenous vegetation on mined substrates and develop an understanding of species assemblage and habitat preference in the Karibib thorn bush savannah. The main objective has been set to contribute scientific information to the development of methodologies for using mined substrates to establish self-sustaining, indigenous plant communities and to the development of mine closure and rehabilitation plans. To accomplish this goal, three studies as summarized below were carried out in the form of this MSc.
The first study determined the plant communities and their habitats in the surrounding and around undisturbed ecosystems in the Karibib thorn bush savannah. Here, a vegetation survey was carried out in five undisturbed habitats namely; Marble hills, Sandstone hills, Granite hills, Calcrete plains and Kalahari red sand plains. Walking belt transects were used to collect community data and soil samples were collected in each habitat. Species diversity, composition, evenness and richness were determined for each habitat. Ordinations and correlations were used to determine the relationships between plant species and soil variables and niche breadth for each plant species was determined to show the degree of specialization for each species. Ordinations of woody vegetation in the Karibib thorn bush savannah indicated that there were fairly distinct species assemblages. Identified species assemblages were related to soil properties. The second study investigated the germination requirement of eight selected woody species to determine the best seed treatment for each species. Sulphuric acid, acetone and hot water scarification methods were used. For each species, there were significant differences in germination percentage between different seed treatments. Sulphuric acid improved germination in all the species, acetone also improved germination in six species, while hot water improved germination in only two species.
The preceding studies provided context for the main study which investigated the establishment of woody savannah species on various mined substrates, since establishment of vegetation requires the knowledge of species assemblages, habitat preferences as well as germination requirements. Much research has been done on native species on mine land rehabilitation but few studies have correlated native species establishment with mined substrates…

▼ O uso de compostos orgânicos é importante para economia e sustentabilidade ambiental, devido apresentarem custo baixo para obtenção e transporte, além de auxiliar na absorção de nutrientes pela planta. O trabalho teve como objetivo avaliar o efeito de compostos orgânicos no cultivo em vaso de crisântemo. As cultivares de crisântemos estudadas, Miramar e Elliot, foram cultivadas em substrato comercial acrescentados de adubo mineral, embiotic, bokashi ou húmus originando 10 tratamentos: adubo mineral; embiotic + adubo mineral; bokashi + adubo mineral; húmus + adubo mineral; húmus + embiotic; húmus + bokashi; húmus + embiotic + bokashi; embiotic; bokashi e embiotic + bokashi, sob ambiente protegido. Os substratos foram analisados quanto às características físicas, químicas e nutricionais. O delineamento experimental, de cada experimento, foi em blocos casualizados, com dez tratamentos e oito repetições, sendo cada vaso composto por seis estacas apicais pré-enraizadas com aproximadamente 12 cm de altura. Os parâmetros fitométricos avaliados aos 90 dias após o plantio foram: altura da planta, diâmetro da haste principal, número hastes secundárias, número de folhas, número de inflorescências, diâmetro de inflorescência e massa seca da parte aérea. Foram realizadas análises dos teores de nutrientes da parte aérea e de clorofila. Os dados fitométricos foram submetidos à análise de variância e as médias comparadas pelo teste de Tukey a 5% e os teores de nutrientes e de clorofila por Análise Fatorial Múltipla e Análise de Agrupamento. A adubação mineral associada à bokashi ou húmus resultou em maior porosidade, menor densidade, e maior teor nutricional no substrato, características desejáveis para melhor desenvolvimento da cultura. Para cultivar Miramar a utilização de húmus ou bokashi no substrato associado a adubação mineral, favoreceu o desenvolvimento da planta, respectivamente fase vegetativa e reprodutiva. Para cultivar Elliot os substratos com embiotic, bokashi e húmus associados à adubação mineral apresentaram os melhores resultados. O teor de clorofila foi maior nos substratos com adubação mineral, exceção húmus + adubação mineral. Os maiores teores nutricionais da planta foram obtidos quando houve adição de adubação mineral ao embiotic e bokashi no substrato. O embiotic adicionado isoladamente ao substrato comercial não deve ser recomendado para cultivar Miramar e também para Elliot.
The use of organic compounds is important for economic and environmental sustainability, given present low cost to obtain and transport, besides assisting in the absorption of nutrients by the plant. The study aimed to evaluate the effect of organic compounds in the cultivation of potted chrysanthemum. Chrysanthemum cultivars studied, Miramar and Elliot, were grown on commercial substrate added of mineral fertilizer embiotic, bokashi or humus resulting 10 treatments: mineral fertilizer; embiotic + mineral fertilizer; bokashi + mineral fertilizer; humus + mineral fertilizer; humus + embiotic; humus + bokashi; humus + embiotic +…

▼ O trabalho teve por objetivo avaliar o efeito de substratos e luminosidades sobre a emergência de sementes e desenvolvimento inicial de três genótipos de pitaia, Hylocereus undatus, H. undatos x H. costaricensis e H.costaricensis x H. undatus. O experimento foi conduzido em casa de vegetação na Universidade Estadual de Londrina (UEL). Testaram-se os substratos vermiculita de granulometria média, casca de arroz carbonizada, substrato comercial Plantmax HÁ ® e fibra de coco Amafibra padrão 80 ®, todos umedecidos a 70% da capacidade máxima de retenção de água. As luminosidades testadas foram 25; 50; 75 e 100%. Para se obter os níveis de sombreamento utilizaram-se telas de polipropileno de coloração preta. O delineamento experimental foi o inteiramente casualizado, em esquema fatorial 3x4x4, sendo três genótipos de pitaia, quatro substratos e quatro sombreamentos, com quatro repetições de 50 sementes cada. A avaliação constituiu-se de porcentagem de plântulas emergidas, índice de velocidade de emergência e tempo médio de emergência. Após cinco meses foram avaliados: número de plantas sobreviventes, comprimento da maior raiz, de parte aérea e total e massa seca das plântulas. Os dados foram submetidos à análise de variância e comparados pelo teste de Scott-Knott a 5%. De modo geral os melhores resultados foram obtidos pelos híbridos, nas luminosidades intermediárias e no substrato fibra de coco.
The study aimed to evaluate the effect of substrates and luminosities on the emergence and early development of seeds of three genotypes pitaya, Hylocereus undatus, H. undatus x H. costaricensis and H. costaricensis x H. undatus. The experiment was conducted in a greenhouse at the Universidade Estadual de Londrina (UEL). Substrates were tested an average particle size of vermiculite, rice hulls, substrate Plantmax THERE ® and coconut fiber Amafibra standard 80 ®, all moistened to 70% of maximum capacity to retain water. The luminosities tested were 25, 50, 75 and 100%. To obtain the shading levels were used meshes of black color. The experimental design was completely randomized in a factorial 3x4x4, three genotypes pitaya, four substrates and four shades, with four replications of 50 seeds each. The evaluation consisted of seedling emergence, speed of emergence and mean emergence time. After five months were evaluated: number of surviving plants, length of root, shoot and total dry mass of seedlings. Data were subjected to analysis of variance and compared by Scott-Knott test at 5%. Generally the best results were obtained by hybrid intermediate the luminosities and coconut fiber substrate.

▼ Pitaya é o nome dado aos frutos de diversas cactáceas de hábito trepador, nas quais algumas espécies têm demonstrado aceitação para a comercialização. A propagação comercial das espécies de pitaya é feita por estaquia, onde se obtêm plantas com maior uniformidade e precocidade na produção. Diversos são os fatores que afetam a formação das raízes nas estacas como o tipo de substrato, umidade, temperatura, concentrações de fitohormônios e época do ano em que é realizada a estaquia. No caso da pitaya, que se apresenta como uma cultura nova no Brasil, são escassos os estudos sobre as técnicas de produção, incluindo a obtenção de mudas. Desse modo, o objetivo desse trabalho foi avaliar o enraizamento e brotação de estacas de pitaya em diferentes substratos, concentrações de ácido indolbutírico (AIB), veículos de diluição, formas de aplicação e períodos do ano, na região de Londrina - PR. No primeiro experimento foram testados os substratos: areia, vermiculita, casca de arroz carbonizada e casca de pínus, onde foram plantadas estacas tratadas e não tratadas com AIB (3000 mg.L-1) das espécies Hylocereus undatus, Hylocereus polyrhizus e Selenicereus megalanthus. No segundo experimento, estacas de H. undatus foram tratadas com soluções de AIB nas concentrações de 1500 e 3000 mg.L-1, nos seguintes veículos de diluição: etanol (50%), KOH (1N), NaOH (1N) e talco, tendo-se um controle sem aplicação de AIB. No terceiro experimento, estacas de H. undatus foram coletadas e plantadas no 15º dia de cada mês de 2011, sendo avaliadas em 60 dias após a data de cada plantio. As variáveis avaliadas nos experimentos foram: porcentagem de sobrevivência, brotação e enraizamento, número e comprimento dos brotos, número, comprimento da maior raiz, comprimento médio, massa seca e volume das raízes. Em relação ao número, comprimento médio e massa seca das raízes, observou-se que a vermiculita foi o substrato mais adequado para todos os genótipos, sendo o uso do AIB favorável para H. undatus e H. polyrhizus. Em S. megalanthus a utilização de AIB não se mostrou necessária. A concentração de 3000 mg.L-1 de AIB, em NaOH, favoreceu o enraizamento e a brotação das estacas de H. undatus, apresentando média inferior para a porcentagem de brotação apenas quando comparada ao tratamento em KOH 1500 mg.L-1 (90 e 100%, respectivamente). Observaram-se os maiores valores para porcentagem de enraizamento e para o número de raízes de H. undatus no período de janeiro a março, em maio e de setembro a dezembro. Para o comprimento médio e da maior raiz, as maiores médias foram observadas de janeiro a março e de outubro a dezembro. Em relação ao número de brotos por estaca, as maiores médias foram observadas entre agosto a novembro, e para o comprimento dos brotos em março e no período de julho a dezembro. Concluí-se que o substrato vermiculita, com aplicação de 3000 mg.L-1 de AIB com NaOH como veículo de diluição em estacas enraizadas nos meses mais quentes do ano, são as condições mais indicadas para o enraizamento de estacas de pitaya.

▼ Street trees are an important part of a comfortable urban environment. Their beneficial effects in the built environment have been documented in a number of ways around the world. In urban environment tree roots are often grown in limited volumes of soil and competing for space with artificial construction materials and technical structures. Low oxygen concentrations in urban soils are considered as one of the major growth limiting factors, particularly under street pavements.
The terrestrial growth conditions are difficult to alter in urban environment. By improving below-ground conditions, tree well-being and sustainability can be significantly increased.
Increased ensign of growing conditions and the awareness of the value of urban trees have contributed to the creation of landscaping applications such as structural soil.
This study compared gas concentrations in the air of structural and conventional soils, used in roadside tree plantings in the City of Helsinki. Soil air samples were collected during growing seasons 2012 and 2013. Proportions of nitrogen, oxygen, carbon dioxide and methane in soil air were determined by a gas chromatograph. CO?-fluxes were used to evaluate the effect of the soil surfacing material to ground ventilation.
Structural soil contained more oxygen in all depths compared to conventional tree soil. A strong correlation existed between oxygen and carbon dioxide concentrations. It seems that cobblestone coating with wide seams does not impair the ground ventilation compared to soil covered with cast-iron grate. Atmospheric growth conditions were more favorable in the structural soil; however the oxygen concentrations in conventional soil were also high.

▼ Ce travail vise à développer un modèle générique capable de mieux rendre compte et de prédire les transferts de radionucléides dans le système sol/solution du sol/plante. La première partie de ce travail a été consacrée à l’analyse critique des modèles disponibles dans la littérature pour décrire l’adsorption du césium par les minéraux argileux (principal processus contrôlant sa disponibilité dans les sols). Cette analyse a débouché sur la formulation d’un nouveau modèle mécaniste combinant deux approches: la complexation de surface et l’échange d’ions. Cette approche, a été testée afin de modéliser l’adsorption du Cs sur plusieurs substrats argileux naturels. Ce travail a permis de valider le modèle proposé et de démontrer qu’il constitue un avantage majeur par rapport aux différents modèles existants. La deuxième partie a été consacrée, à la réalisation d’une série d’expérimentations, conduite en milieux contrôlés sur des systèmes dynamiques, et la modélisation de la (bio)disponibilité du Cs dans ces systèmes. A la suite de ces essais, les interactions entre solide et solution observées ont pu être correctement reproduites à partir du modèle proposé en prenant en compte la fraction argileuse du sol uniquement. Ces simulations ont également été comparées aux simulations obtenues à partir des modèles empirique (Kd) et cinétique (EK). Enfin, le développement d’un outil numérique permettant de coupler la description des interactions géochimiques au transfert vers la plante (approche cinétique) a permis de reproduire correctement les essais réalisés en Rhizotests couplant sol, solution et plante et de mieux caractériser la fraction du Cs disponible pour les plantes.
The overall objective of this work is to develop a generic model able to better account and predict the transfer of radionuclides in the soil / soil solution / plant. The first part of the work was devoted to the critical analysis of the models available in the literature to describe the cesium adsorption on clay minerals (the process that mainly controls its availability in the soils). This analysis enabled us to propose a new mechanistic model combining two approaches: surface complexation and cation exchange. Our approach has been tested in order to model the adsorption of Cs on several natural clay substrates, in a wide range of Cs concentrations and physicochemical conditions. This work allowed to validate the proposed mechanistic model and to demonstrate that it constitutes a major advantage over the various existing models. The second part was devoted, to the performing of a series of experiments, carried out in controlled environments on dynamic systems and modeling the (bio)availability of Cs in these systems. Following these tests, the observed interactions between solid and solution could be correctly reproduced with the proposed model taking into account only the clay fraction of the soil. These simulations were also compared with simulations obtained using a empiric (Kd) kinetic models (E-K approach). Finally, the development of a numerical…

As acácias são plantas invasoras capazes de invadir o território das espécies nativas e de
ameaçar a conservação dos habitats naturais, contribuído para a diminuição da
biodiversidade. No entanto, os detritos vegetais oriundos da remoção dos arbustos de
acácia poderão representar materiais alternativos, após compostagem, para a formulação de
substratos que possam ser utilizados como substitutos da turfa, da casca de pinheiro ou de
outros materiais orgânicos habitualmente utilizados na formulação de substratos.
Neste estudo avaliou-se a capacidade de utilização de compostos de acácia (Acacia
longifolia e Acacia melanoxylon) para substituição do composto de casca de pinheiro na
formulação de substratos hortícolas. Produziram-se diversos substratos com percentagens
crescentes de composto de acácia em substituição do composto de casca de pinheiro
utilizado num substrato comercial constituído por 30% de turfa e 70% de casca de pinheiro
(v/v) e designado por Siro Plant. O composto de acácia resultou de duas pilhas de
compostagem com diferente número de revolvimentos.
Os substratos foram avaliados através de testes de germinação de agrião, em placas de
Petri, utilizando extratos aquosos com doses crescentes dos compostos, e em testes de
crescimento, em vasos, com alface (Lactuca sativa var. crispa) e couve lombarda
(Brassica oleracea sabauda L.). Com base no substrato comercial (sem adubo e com
adubo) utilizaram-se os compostos de acácia das duas pilhas de compostagem para
substituição do composto de casca de pinheiro (v/v) nas doses de 30%, 60% e 100% em
volume. Os tratamentos (17) incluíram ainda os substratos comerciais, os compostos de
acácia sem mistura, e solo sem substrato ou composto.
Os compostos de acácia para o extrato aquoso com 20% (v/v) não apresentaram
fitotoxidade, o que foi confirmado pela percentagem de germinação superior à
percentagem de germinação do controlo. Não houve diferença significativa na
percentagem de germinação com os diferentes substratos e também em relação ao substrato
Siro Plant.
A produtividade de alface com o composto de acácia da pilha com maior revolvimento foi
superior à verificada no substrato comercial sem adubo, e semelhante ao substrato
comercial com adubo, no ensaio com doses crescentes de composto de acácia. A
vi
produtividade também aumentou em misturas com o composto da pilha com menor
revolvimento em comparação com o substrato sem composto.
O ensaio com couve, tal como com alface, demonstrou que a substituição do composto de
casca de pinheiro por composto de acácia na formulação de substratos de plantas para
vasos não tem qualquer inconveniente, podendo, pelo contrário, ser vantajoso para a
composição de substratos que não tenham sido fertilizados com adubos minerais.
Com base nos resultados obtidos pode-se concluir que o composto de acácia poderá

▼ Freshwater is a finite resource that is rapidly becoming more scrutinized in agricultural consumption. Specialty crop producers, especially ornamental crop producers, must continually improve production sustainability, with regards to water resource management, in order to continue to stay economically viable. Soilless
substrates were initially developed to have increased porosity and relatively low water holding capacity to ensure container crops would not remain overhydrated after irrigations or rain events. As a result,
substrates were selected that are now considered to be in efficient in regards to water resource management. Therefore, to provide growers with additional means to improve production sustainability, soilless substrate hydrology needs be innovated to provide increased water availability while continuing to provide ample air filled porosity to ensure productive and efficient water interactions. Historically, soilless
substrates have been characterized using "static" physical properties (i.e. maximum water holding capacity and minimum air-filled porosity). The research herein involves integrating dynamic soilless substrate hydraulic properties to understand how substrate hydrology can be manipulated to design sustainable
substrates. This task involved adapting new technologies to analyze hydrological properties of peat and pine bark
substrates by employing evaporative moisture characteristic measurements, which were originally designed for mineral soils, for soilless substrate analyses. Utilizing these evaporative measurements provide more accurate measures of substrate water potentials between -10 and -800 hPa than traditional pressure plate measurements. Soilless
substrates were engineered, utilizing only three common substrate components [stabilized pine bark (Pinus taedea L.), Sphagnum peatmoss, and coconut coir fiber], via particle fractionation and fibrous additions. The engineering process yielded
substrates with increased unsaturated hydraulic conductivity, pore connectivity, and more uniform pore size distributions. These
substrates were tested in a greenhouse with irrigation systems designed to hold
substrates at (-100 to -300 hPa) or approaching (-50 to -100 hPa) water potentials associated with drought stress. Substrate-water dynamics were monitored, as were
plant morphology and drought stress indicators. It was determined that increased substrate unsaturated hydraulic conductivity within the production water potentials, allowed for increased crop growth, reduction in drought stress indicators, while producing marketable plants. Furthermore, individual plants were produced using as low as 5.3 L per
plant. Increased production range substrate hydraulic conductivity was able to maintain necessary levels of air-filled porosity due to reduced irrigation volumes, while providing water for plants when needed. The
substrates were able to conduct water from throughout the container volume to the
plant roots for uptake when roots reduced substrate water potential. Furthermore, increased substrate…

▼ Sustainable landscaping includes utilization of plants requiring few inputs. We chose four species showing potential for use in arid landscapes:
Purshia mexicana, Shepherdia argentea, Shepherdia rotundifolia, and
Alnus maritima. We sowed seeds of
S. rotundifolia, S. argentea and
P. mexicana in three
substrates with various water-holding properties due to differing amounts of organic matter (OM). S. rotundifolia germination was maximized in a calcined clay (66.2%) containing no OM and had low germination (12.7 - 21.8%) in the other
substrates. S. argentea germination (42.3 to 53.7%) was similar in all
substrates. Poor seed quality of
P. mexicana resulted in inconclusive results. Our results suggest that germination of some species is enhanced by
substrates with excellent drainage properties. We also investigated effects of different rates of controlled-release fertilizer (CRF) on symbiotic nodule formation in seaside alder. We found that lower than prescribed rates of CRF enhanced nodulation without compromising nitrogen status.

▼ The red rose cultivar ‘Eurored’ was cultivated in plastic greenhouse and open hydroponic system under two water regimes and three different substrates. The aim of the present study was to provide a better insight into the adaptive processes within Rosa hybrid plants cv. Eurored grown in soilless cultivation when exposed to water deficit. Also, the study and evaluation of the local and easily available substrates using in hydroponics and finally, the identification of plants effects from the particular cultivation system in order to improve productivity. Next, postharvest behavior of rose stems were evaluated relatively to the fast reversal of balance between water absorption and transpiration of cut flower stems during vase life and the investigation of physiological and biochemical changes that take place after harvesting. Rose plants were grown under three different substrates conditions (perlite, pine bark-almond shells 1:1(v/v), and perlite-pumice 1:1(v/v)) and two water regimes (100% and 67% of the irrigation needs). At the beginning, seasonal changes (spring, summer and winter) in photosynthetic parameters, water relations, leaf chlorophyll content, chlorophyll fluorescence and flower stem production were quantified. The photosynthetic rate of young rose leaves had higher values during spring, reduced while winter and obtained the lowest values during summer. Photosynthetic active radiation (PAR) and relative humidity (RH, %) correlated with photosynthesis positively at both water regimes and leaf temperature negatively. Also chlorophyll content of the young leaves showed a high positive correlation with photosynthesis. Stomatal conductance of the young leaves showed the lower value during summer and intercellular CO2 of the same leaves showed an inverse pattern from leaf photosynthesis. The mean value of the seasons was shown that mild water stress leads to a) a negative effect on the photosynthetic rate and stomatal conductance although there was no reduction on the intercellular CO2, b) a decline of leaf chlorophyll and chlorophyll fluorescence, c) a decrease on the transpiration rate, leaf water potential (LWP) and relative water content (RWC), however water use efficiency (WUE) was increased, d) a reduction on the total production of flower stems, however, the number of extra quality flower stems was not affected. However, substrates did not affect any physiological or biochemical or growth parameters. As a result the reduced metabolic energy represses growth. Also daily changes were quantified in photosynthetic rate (Pn), stomatal conductance (Cs), intercellular CO2 concentration (Cint, ppm), leaf temperature (oC) photosynthetic active radiation (PAR) and relative humidity (RH, %) and leaf water potential (LWP) at the 2-3h and at 6-7h after the sunrise. Stomatal conductance and the intercellular CO2 concentration had positive correlation with photosynthesis, as well as the intercellular CO2 concentration had positive correlation with stomatal conductance. Photosynthetic rate, stomatal conductance and leaf…

▼ Carbon dioxide from biogas production is currently considered to be without value and isbecause of this released into the atmosphere in the biogas upgrading process. The residualgas is a potential carbon source and can create value in the biogas manufacturing process.By finding a suitable value-creating process that utilizes carbon dioxide, it can be possibleto provide both economic and environmental incentives for companies to develop theiroperations. This project explored the possibility to create value from this CO2. Through anevaluation of the technical maturity of CCU technologies, a recommendation could be givenat the end of the project. An analysis of technical barriers, such as pollutants in the gas, aswell as barriers in the form of competence and corporate culture were examined in orderto provide a reasoned recommendation. The project mapped which value-creating systemswould be suitable for biogas producers in a Swedish context. This included established methaneand carbon dioxide upgrading techniques currently in use and suitable CCU techniquesthat can interact with the selected upgrading processes and serve as value creators. Based onthis survey, it was then possible to identify common, critical variables for these systems. Thereafter,a recommendation of an appropriate CCU technology could be given depending onthe CO2 composition produced. One conclusion from the study was that carbon dioxide concentrationsfrom the residual gas was often high (approx. 97-98 %) and did not contain anycorrosive or toxic components, and that this largely depends on how the digestion reactor ishandled in the production process. Thus, questions were raised about what the actual limitationsof the CCU are, as they did not seem to be technical. CCU techniques that proved to beof particular interest were pH regulation of sewage plants, CO2 as a nutrient substrate for thecultivation of microalgae, and manufacturing of dry-ice for refrigerated transports. All of thesetechnologies currently have a sufficiently high degree of technical maturity to be installedalready today. Other CCU techniques, such as "’Power to gas”, require a high CO2 concentrationand were discarded as the literature review did not suggest the economic potential forthem as they require additional CO2 upgrading steps. Instead, CCU techniques were chosenthat could be implemented directly with the existing CO2 quality. Furthermore, it was concludedthat one reason why CCU technologies have not been widely implemented is internalbarriers between distributors and manufacturers (or users) of CCU technologies. Thus, theuse of carbon dioxide from biogas production and implementation of CCU technologies canbe promoted by eliminating barriers in companies, such as a lack of both knowledge andfinancial incentives.

▼ In the present thesis three where the key aims: 1) to evaluate the dispersion of tracemetals during MSW management at the EMAK “Mechanical, Recycling and Compost”producing municipal solid waste (MSW) Treatment plant (Mechanical and BiologicalTreatment, MBT) of the city of Athens, 2) to define the quality of the plant‟s products, RDFand compost, and 3) to identify the mobility of a series of metals, namely Cu, Mn, Zn, Pb, Cdand Cr when using the compost for cultivation of turf grasses and ornamentals.Systematic sampling of MSW, RDF and compost was taking place from 13/6/2006 to31/5/2007. Heavy metal concentrations were determined by employing Atomic AbsorptionSpectrometry. The results show that the mechanical treatment of MSW enriches RDF andcompost in heavy metals. Nevertheless, both products comply with the EuropeanCommission‟s norms and legislation and Greek Government‟s laws and are considered safefor use.Grass varieties C. dactylon and F. arundinacea, were treated with MSW compost atrates 12% and 25% by volume. MSW compost treatments increased soil heavy metalcontent, although the tissue and the leaching water content did not show any dramaticalincrease. No signs of phytotoxicity were observed in any of the above cases.MSW compost was mixed with a peat-based growing-media at rates of 12.5%, 25%,and 37.5% by volume. Ornamental species Ligustrum japonicum grew in those mixtures withand without addition of NPK fertilizer. In the non-fertilized treatments, the increase of MSWcompost ratios to peat resulted also in higher heavy metals concentration in plant tissue.Fertilization increased even more the concentration of heavy metals in the tissues of theplants examined in most of the cases. Copper does not follow this general trend of themetals studied, eventually due to formation of very stable not bioavailable copper complexeswith organic legands deriving from the compost
