Abstract:
Methods to enhance sweetgum (Liquidambar styraciflua L.) in vitro axillary shoot formation and shoot establishment into soil are presented. Sweetgum shoots grown in an automated plant culture system (APCS) produced 400 to 500 shoots via axillary branching compared to only 40 shoots produced within Magenta vessels containing agar medium after 8 weeks of incubation. Vitrification was observed in as many as 80% of the axillary shoots produced in the APCS. A continuous carbon dioxide (CO2)-flow-through system was tested on both vitrified and non-vitrified sweetgum shoots transferred from the APCS to soil. One- and two-cm-long vitrified shoots were grown within CO2-flow-through system chambers and subjected to 350, 1500, 3000, 10,000, or 30,000 μL·L–1 (ppm) CO2 for 4 weeks. Administering 10,000 μL·L–1 CO2 improved culture survival and enhanced overall shoot and root growth compared to shoots grown under ambient atmosphere (i.e., 350 μL·L–1 CO2).

Abstract:
Abstract Background and Aims The success of using bent shoots in cut-rose (Rosa hybrida) production to improve flower shoot quality has been attributed to bent shoots capturing more light and thus providing more assimilates for flower shoot growth. We aimed at quantifying this contribution of photosynthesis by bent shoots to flower shoot growth. Methods Rose plants were grown with four upright flower shoots and with no, one or three bent shoots per plant. Plant architectural traits, leaf photosynthetic parameters and organ dry weight were measured. A functional–structural plant (FSP) model of rose was used to calculate photosynthesis of upright shoots and bent shoots separately, taking into account the heterogeneous canopy structure of these plants. Key Results Bent shoots contributed to 43–53 % of total assimilated CO2 by the plant. Plant photosynthesis increased by 73 and 117 % in plants with, respectively, one and three bent shoots compared with plants without bent shoots. Upright shoot photosynthesis was not significantly affected by the presence of bent shoots. However, upright shoot dry weight increased by 35 and 59 % in plants with, respectively, one and three bent shoots compared with plants without bent shoots. The increased upright shoot dry weight was entirely due to the contribution of extra photosynthesis by bent shoots, as this was the only source that could induce differences in upright shoot growth apart from their own photosynthesis. At least 47–51 % of the photosynthesis by bent shoots was translocated to upright shoots to support their biomass increase. Conclusions Based on model simulations, we conclude that the positive effect of shoot bending on flower shoot growth and quality in cut-rose production system can almost entirely be attributed to assimilate supply from bent shoots. FSP modelling is a useful tool to quantify the contributions of photosynthesis by different parts of heterogeneous canopies.

Abstract:
Fluctuating water levels, which characterize freshwater marshes of the Florida Everglades, U.S.A., constrain growth in emergent macrophytes. We studied acclimation of Eleocharis cellulosa Torr. (Cyperaceae) in mesocosms to water depths of 7 and 54 cm and to switching between these water depths. After 80 weeks at fixed depths, deepwater plants produced (i) taller, thicker, and fewer shoots; (ii) fewer ramets; (iii) less biomass; and (iv) greater shoot biomass relative to root and rhizome biomass. Despite large differences in shoot lengths between water depths, shoot heights above the water surface were similar. Emergent shoot tissues had thick secondary walls in the epidermal cells and several palisade layers beneath; submerged shoots lacked this anatomy. When shallow-water plants were transferred to deep water, shoots elongated rapidly, with younger shoots elongating more than older ones. When deepwater plants were transferred to shallow water, emergent shoots quickly died and were replaced by new shoots. Overall, plants exposed to rapid changes in water level adjusted biomass allocation patterns after 9 weeks towards those of control plants in their new environment, but deepwater plants responded more slowly than shallow-water plants. These shifts may allow E. cellulosa to produce shoots that optimize biomechanical support and aeration.Key words: biomass allocation, Eleocharis cellulosa, Everglades, gas exchange, shoot demography, wetland plants.

Abstract:
Rhododendron `Montego' shoot cultures initiated from plants with and without tissue proliferation (TP and NTP) served as explant sources for all studies (Note: in vitro TP shoot cultures produce primarily dwarf shoots, some long shoots, and stem tumors). Calli induced from TP leaves and tumors and NTP leaves were cultured on woody plant (WP) medium containing NAA and 2-iP. During the first 4 weeks of culture, calli from NTP leaves had higher relative growth rates than calli from TP leaves or tumors. However, calli from TP leaves and tumors grew faster than calli from NTP leaves for all subculture periods that followed. Shoot tips (5 mm) were excised from TP dwarf shoots, TP long shoots, and NTP shoots and were cultured on WP medium with or without 15 μM 2-iP. Shoot tips from TP dwarf and long shoots multiplied on medium without 2-iP, averaging 18.4 and 1.7 shoots per shoot tip in 12 weeks, respectively. Shoot tips from NTP shoots only multiplied when maintained on 2-iP-containing medium. When placed on 2-iP-containing medium, both types of TP shoot tips produced clusters of callus-like nodules that gave rise to highly tumorized, short shoots or leafy meristems.

Abstract:
Rooted cuttings of Betula nigra ‘Heritage’ originating from short shoots were either staked and lateral shoots pruned to a 3 node length or were unstaked and unpruned. One hundred and twenty-five days following propagation, the pruned and staked plants had higher net assimilation rates and lower leaf area ratios than unstaked and unpruned plants. No differences in relative growth rates, total dry weight, root/shoot ratios or shoot length were observed between control and treated plants. Pruned and staked plants had, relative to unstaked and unpruned, less leaf surface area composed of fewer but larger leaves which produced more grams of dry weight per cm2 leaf surface area per day. Pruning and staking maximized economically important dry matter production without reducing total dry weight. Plants originating from long shoots had greater root, shoot and total dry weights, and required less staking to produce upright growth than plants originating from short shoots. By exploiting the beneficial topophysis growth of long shoots, nursery productivity can be increased.

Abstract:
We have produced a number of transgenic citrus plants via Agrobacterium-mediated transformation of seedling stem segments with a vector plasmid containing a β-glucuronidase (GUS) gene. All regenerated green shoots produced in our experiments are assayed histochemically for expression of GUS by cutting a section from the base of the shoot. Many of the shoots express GUS only in sectors, which vary in size from shoot to shoot. Analyses suggest that sectored regenerated shoots are chimeric, consisting of nontransformed cells as well as transformed cells. However, plants derived from shoots with large GUS+ sectors in the original assays do not necessarily contain the GUS gene; conversely, some plants derived from shoots with small sectors appear solidly transformed. Plants that appear solidly transformed have maintained gene expression for up to 5 years. None of the transgenic plants have obviously altered morphologies. It has not been possible to analyze progeny plants because of the long juvenile periods and polyembryony of the primary transformants. However, because citrus is clonally propagated, long-term phenotypic stability of primary transformants is the most important factor in producing useful transgenic plants.

Abstract:
Bud cultures from nonjuvenile field clones of lowbush blueberry (Vaccinium angustifolium Ait.) were established on Z-2 medium with 59 μm 2iP. Reversion to juvenile characteristics with small and rounder leaves occurred only on two explants after 19 weeks in culture. These shoots grew vigorously and could be easily subcultured. The number of shoots of one clone doubled every 23.3 days. Reducing the 2iP concentration to 12.3 and 24.6 μm reduced shoot proliferation, but permitted better shoot elongation. After 5 weeks in a mix of 3 peat: 2 vermiculite: 1 perlite, shoots >20 mm rooted better than shoots measuring 10 to 20 mm. Chemical names used: N-(3-methyl-2-butenyl)-1-H-purine-6-amine (2iP); 1H-indole-3-acetic acid (IAA).

Abstract:
Dendranthema ×grandiflorm (Ramat.) Kitamura `Powerhouse' plants were pinched to five nodes and grown in growth chambers at 35C day temperature (DT) and 14,17,21,24, or 27C night temperature (NT) to determine if NT influenced lateral shoot development on plants exposed to high DT. Vegetative cuttings were removed from two successive flushes of lateral shoots and evaluated for lateral shoot development after rooting and subsequent apex removal. Lateral shoot development was determined on a third flush of shoots that developed on the stock plants. The percentage of nodes that developed lateral shoots on stock plants or vegetative cuttings was not related to NT. The percentage of first-order, second-order, and third-order axillary nodes that developed a lateral shoot on the stock plants, averaged over all NT, was 76, 65, and 12, respectively. The percentage of nodes that developed lateral shoots on the first-order and second-order cuttings was 29 and 19, respectively. We concluded that cool NT were ineffective in preventing a decrease in lateral branching on plants grown under high (35C) DT conditions.

Abstract:
Fruit set in some species of citrus is greater on mixed shoots (leafy inflorescences) than on generative shoots (leafless inflorescences). Combination treatments involving water stress, cool winter night temperatures, and branch pruning were used to manipulate the number of shoots and ratios of the three shoot types in containerized `Tahiti' lime (Citrus latifolia Tan.) plants. Plants were water stressed in a greenhouse for five weeks, pruned after rewatering, transferred to the open environment, and observed three weeks later. Appropriate control plants were carried along with treated ones. Combination treatments of all three variables increased the number and ratio of mixed shoots four fold over the non-stressed, non-pruned controls. More shoots formed on non-pruned, water stressed plants than on controls. Both formed predominantly generative shoots. Shoots of pruned, non-stressed plants were predominantly vegetative. Non-pruned non-stressed plants were typical of those growing in the field exposed to cool winter nights.

Abstract:
Poinsettia stock plants consist of a dense canopy of competing shoots, and the growth and development of these individual shoots have not been previously quantified. The effects of air temperature, daily light integral (DLI), and canopy density (CD) were investigated on poinsettia (Euphorbia pulcherrima Willd. ex. Klotsch) ‘Freedom Red’ shoot development in a stock plant canopy. Plants were grown at two constant temperatures (20.3 or 25.7 °C), five CD (43, 86, 129, 172, or 215 shoots/m2), and three DLI treatments (2.6, 4.4, or 7.7 mol·m−2.d−1 for the September planting and 4.0, 6.0, or 10.6 mol·m−2.d−1 for the January planting). Shoot position at the final data collection was used to assign shoots to different levels within the canopy; Level 1 = the four highest shoots, Level 2 = the next four highest shoots, and so forth for Levels 3, 4, and 5. Temperature did not significantly affect leaf unfolding rate (LUR), shoot fresh mass (FM), or shoot caliper, whereas DLI and CD affected shoot growth and development. LUR and FM increased as DLI increased from 2.6 to 10.6 mol·m−2.d−1, whereas LUR and FM decreased on the uppermost shoots in the canopy, e.g., Level 1 shoots, as CD increased from 43 to 129 shoots/m2. Therefore, higher CD required higher DLI to achieve similar LUR and FM. Shoot caliper on Level 1 shoots increased from 6.3 to 7.4 mm as CD decreased from 129 to 43 shoots/m2; and shoot caliper increased from 5.8 to 7.6 mm as DLI increased from 4.0 to 10.6 mol·m−2.d−1. The DLI environment needs to be managed to accommodate greater CD, to sustain growth and development of individual shoots within the canopy of poinsettia stock plants.

Abstract:
A mist reactor was used to study plant growth and development under various environmental conditions towards the production of healthy plantlets ready for soil transplant in one step from inoculation. In addition, a 3D type of cultivation via surface attachment of explants to vertically hanging strips inside the mist reactor was also investigated to maximize productivity with minimal footprint. Using carrot as the model species, pre-embryogenic cell suspensions were successfully spray-inoculated onto hanging poly-L-lysine (PLL)-coated nylon mesh to which they then attached and remained for several weeks while they developed into rooted plantlets. To study single step micropropagation from shoot explants to fully acclimatized plantlets, Artemisia annua was used as the model species. Nodal cuttings of A. annua were inoculated onto PLL-coated mesh strips by briefly immersing the strips in the suspension of nodal cuttings. Investigation of medium, phytohormones, CO2, ventilation level and humidity ensued resulting in selection of a preferred final process that reduced physiological aberrations like hyperhydricity and was time efficient. The nodal cuttings that attached to the strips were first misted with half strength shooting medium for 7 days to develop new shoots. Then the new shoots were misted with the rooting medium supplemented with NAA for 12 days to develop roots. Rooted plantlets were acclimatized in the same rooting medium for 9 days to acquire fully functional stomata prior to planting into soil. Taken together this study suggested that fully developed plantlets ready for planting into soil could be obtained in a single step in a bioreactor from embryogenic cells or from nodal explants.

Resumo: O mercado mundial da floricultura tem incentivado a introdução e produção de novas plantas tropicais, cujas formas inusitadas, exuberantes e coloridas têm alto potencial ornamental. No Brasil, o cultivo para a produção de flores tropicais vem aumentando, graças às condições ambientais favoráveis, à disponibilidade de terras, água e energia, além da mão de obra relativamente barata, que incidem diretamente na qualidade do produto e possibilitam custos competitivos nos mercados externos. Porém, existem limitações para a expansão de produtos novos, dentre elas, a falta de informação quanto às condições de cultivo intensivo de espécies potenciais e a sua conservação em condições tropicais. As espécies do gênero Costus (Costaceae) vêm despertando grande interesse ornamental devido às suas inflorescências que apresentam beleza e exoticidade. O objetivo do presente trabalho foi estudar o crescimento, a propagação, a floração e os carboidratos de reserva em plantas de Costus arabicus L. cultivadas sob condições de casa de vegetação, com vistas a oferecer conhecimento fisiológico e informações técnicas para o cultivo dessa espécie como planta ornamental. Plantas de C. arabicus foram transplantadas para vasos e mantidas sob condições de casa de vegetação. As plantas foram submetidas a tratamentos fotoperiódicos de 8, 12, 16 e 20 h, avaliando-se o crescimento vegetativo (brotações, hastes, altura e número de folhas) e a floração. Para o estudo da propagação vegetativa, os rizomas de C. arabicus foram divididos em suas regiões distal, mediana e proximal e cultivados em diferentes épocas: plantio realizado em julho (inverno), com as plantas matrizes em estádio prévio à floração; plantio realizado em novembro (primavera), com as plantas matrizes em floração; e plantio realizado em março (outono), com as plantas matrizes em estádio vegetativo. A floração foi avaliada pelo aparecimento de botão floral, pela fase de desenvolvimento da inflorescência, número de flores desenvolvidas e tempo decorrido da antese até a senescência da flor. Foram realizadas análises de amido e carboidratos solúveis (açúcares totais e redutores) do rizoma e foram registradas a massa fresca (MF) e a massa seca (MS) da parte aérea e do rizoma e calculada a razão MF/MS. O delineamento experimental utilizado foi o inteiramente casualizado. As médias dos tratamentos foram comparadas segundo Tukey com 5% de probabilidade. Os resultados indicaram que as variáveis de crescimento analisadas foram influenciadas pelo fotoperíodo e favorecidas por dias longos. De modo geral, a capacidade propagativa do rizoma independe da região utilizada, porém a região proximal favoreceu a formação de brotos, principalmente no verão. Plantas de C. arabicus têm ciclo de desenvolvimento anual, com uma fase de crescimento vegetativo, latência no crescimento na época do inverno e floração entre novembro e abril. Botões florais foram observados em todos os tratamentos fotoperiódicos e, portanto, a indução floral não foi uma resposta qualitativa a esse fator ambiental. Contudo, a resposta de floração, com base nos diversos aspectos avaliados foi favorecida no fotoperíodo de 16 h e em termos quantitativos, fotoperíodo de 8 h foi desfavorável para a floração. A melhor época de plantio visando à floração foi no mês de julho, pois o processo de floração ocorreu após apenas quatro meses de cultivo das plantas, quando comparadas com as plantas obtidas de rizomas cultivados em novembro e março, que levaram aproximadamente 12 e 8 meses, respectivamente, para florescer. O amido foi considerado o principal carboidrato de reserva do rizoma e foi hidrolisado durante o processo de floração, enquanto os açúcares totais foram utilizados como fonte primária de energia para a brotação dos rizomas de plantas de C. arabicus. Os resultados obtidos do crescimento, propagação vegetativa e floração permitem que as plantas de C. arabicus possam ser aproveitadas como plantas ornamentais, visto que suas características morfológicas, como a filotaxia em espiral, a inflorescência esverdeada, as flores brancas com labelo róseo, são aspectos interessantes para o mercado da floricultura.
Abstract: The world market for floriculture is encouraging the introduction and production of new tropical plants, with their unusual forms, exuberant and colorful, with high ornamental potential. In Brazil, the cultivation for production of tropical flowers are increasing due to, favourable environmental factors, availability of land, water, energy and relatively cheap labour which reflects directly on the quality of the products and offers competitive costs in foreign markets. But there are limitations to the expansion of new products, including the misinformation about the conditions of intensive cultivation of new plant species and their potential conservation in tropical conditions. The species of the genus Costus (Costaceae) are attracting great interest because of their ornamental flowers with high beauty and exoticity. The objective of this work was to study propagation, growth, flowering and the reserve compounds in plants of Costus arabicus L. growing under glasshouse conditions, aiming to offer technical information and physiological knowledge for the cultivation of this species as an ornamental plant. Plants of C. arabicus were transplanted to pots and kept under the conditions of a greenhouse. The plants were subjected to photoperiodic treatments of 8, 12, 16 and 20 h. Vegetative growth (shoots, stems, height and number of leaves) and flowering were evaluated. For vegetative propagation, rhizomes of C. arabicus were divided in their distal, middle and proximal regions and were grown in different seasons: planting held in July (winter), when the plants were in a stage prior to flowering; planting held in November (spring), when the plants were flowering and planting held in March (autumn), when the plant were in vegetative stage. Flowering was assessed by the appearance of floral buds, the developmental stage of the inflorescence, the number of flowers developed and elapsed time from anthesis to senescence of the flower. Analysis of soluble starch and carbohydrates (total and reducing carbohydrates) of rhizome were performed. Fresh mass (FM) and dry matter (DM) of the shoot and the rhizome were recorded to calculate the ratio FM/DM. The experimental design was a completely randomized. The averages were compared according to Tukey at 5% probability. The results indicated that the growth of variables analyzed were influenced by photoperiod and favored by long days. In general, the ability of the rhizome to propagate not depends on the region used, but the proximal region favored vegetative growth development, formation of shoots, the development of rods, plant height and number of leaves, mainly on summer. Plants of C. arabicus have annual cycle of development, with a phase of vegetative growth, followed by latency of winter season and flowering between November and April. Floral buds were observed in all photoperiodic treatments, and therefore floral induction was not a qualitative response to this environmental factor. However, the response of flowering, based on the various aspects assessed was favored in the photoperiod of 16 h in quantitative terms, photoperiod of 8 h was unfavorable for flowering. The best season for flowering was when planting is in July, because the process of flowering occurred after only four months of cultivation of the plants, when compared with the plants obtained from rhizomes, cultivated in November and March, which brought about 12 and 8 months, respectively, to flower. Starch was considered the main carbohydrate reserve of rhizome and noted that it was hydrolyzed during the process of flowering, while the total sugar were used as a primary energy source for the sprouting of the rhizomes. The results of growth, vegetative propagation and flowering allow the plants of C. arabicus can be used as ornamental plants since its morphological characteristics, such as spiral phytolaxy, the green inflorescence, and the white flowers with pink labelo, are interesting aspects to the market for floriculture.

Abstract:
L'auxine régule la croissance et le développement des plantes grâce aux facteurs de transcription de la famille des "AUXIN RESPONSE FACTOR" (ARF). Chez Arabidopsis thaliana en particulier, ARF5, 6, 7, 8 et 19 activent l'expression de gènes cibles en réponse à l'auxine. Ces cinq ARF activateurs contrôlent de façon plus ou moins redondante des processus divers au cours du développement de la plante, notamment la régulation des croissances au niveau des méristèmes racinaires et aériens ainsi que la formation des racines latérales ou des méristèmes axillaires.Chacun de ces cinq ARF activateurs présente des patrons d'expression uniques dans chacun des tissus racinaires et aériens, en association avec leurs fonctions particulières. Il est probable que cette expression tissu-spécifique trouve son origine dans un contrôle différencié de leur transcription. Dans cette étude, des régulateurs amonts de la transcription de ARF5, 6, 7, 8 et 19 ont été identifiés par une méthode haut-débit de crible simple hybride en levure (Y1H). Une procédure d'expression transitoire en protoplastes a permis de confirmer que l'expression de chaque ARF activateur est contrôlée par des régulateurs spécifiques, dont la majorité se comportent comme des répresseurs de la transcription des ARF in planta. Parmi les régulateurs identifiés, les facteurs de transcription ont été étudiés grâce à des mutants pour préciser les interactions in planta. Ces mutants montrent des phénotypes développementaux typiques de perturbations de l'auxine dans les racines et les tiges : altérations des cinétiques de croissance, de l'émergence des organes latéraux ou de réponses à l'auxine et modification de l'expression des ARF activateurs.Par ailleurs, ce travail aborde également les dialogues entre les voies de signalisation de l'auxine et des cytokinines, et en particulier le rôle de ces interactions dans le développement des racines et des tiges. Une des interactions identifiées dans le crible Y1H est la répression de ARF7 par CRF10, un gène membre de la famille des "Cytokinin Response Factors". Nous avons mis en évidence l'importance de cette interaction pour le maintien de l'architecture du méristème apical racinaire, pour la sénescence des feuille et pour la réponse phototropique à la lumière bleue dans les hypocotyles
Auxin regulates plant growth and development through the transcription factors of the AUXIN RESPONSE FACTOR (ARF) gene family. Most notably in Arabidopsis thaliana ARF5, 6, 7, 8 and 19 activate expression of target genes in response to auxin. These five ARF activators control both variable and overlapping processes during plant development including regulation of growth at the root and the shoot apical meristems, lateral root and axillary shoot formation. Each of the five ARF activators shows unique tissue-specific expression patterns in the root and the shoot associated with their distinct functions. This tissue-specific expression is likely derived from the differences in the control of ARF activator transcription. In this study the upstream regulators of ARF5, 6, 7, 8 and 19 transcription were identified. This was achieved by utilizing a high-throughput yeast one-hybrid (Y1H) method. The transient protoplast assay revealed that each ARF activator is controlled by specific transcriptional regulators and that the majority of these regulators are repressors of ARF transcription in planta. Mutants of the regulatory transcription factors were utilized to additionally investigate the interactions in planta. These mutants display auxin-related developmental phenotypes in the root and the shoot including alternations in growth kinetics, emergence of lateral organs, responses to auxin and altered expression of ARF activators. Furthermore, this study additionally focuses on cross-talk between the auxin and cytokinin signaling pathways and its role in root and shoot development. One of the interactions identified in the Y1H screen is a repression of ARF7 by CRF10, a member of the Cytokinin Response Factors gene family. The importance of this interaction in maintaining architecture of the root apical meristem, in leaf senescence and in the phototropic response to blue light in hypocotyls is studied

Abstract:
This thesis examines the growth response and inter-relationships between shoots and roots of plants grown in compact soil. In the field, two topsoil and two subsoil conditions were created with five vegetable crops sequentially grown. Between 6 and 12% of the root system grew in the compact subsoil, which had a soil strength of 3.1 c.f. 1.9 MPa in the loosened subsoil. Both the root length density (Lv) and the specific root length were lower in the compact subsoil (80% and 30%, respectively). This had no effect on shoot growth when water and nutrients were well supplied. Compensatory root growth in the lose soil above the compact subsoil occurred in broccoli plants. As a result plants grown in soil with or without a compact subsoil had a similar total root length but with altered root distribution. When the water and nitrogen supplied to the soil was reduced, the lower subsoil Lv in the compact subsoil did not restrict water or N acquisition. This was possibly due to a large increase in the specific uptake per unit length of root, by the fewer roots in the compact subsoil. Compared to the subsoil treatments, only small changes in topsoil physical properties occurred when tillage was ceased. From the field trials the proportion and time of root growth into compact soil appeared important in determining the plant response. In a series of split-root experiments (horizontal and vertical arrangements of compact and loose soil) compensatory root growth in the loose soil only occurred when the root system was exposed to horizontally compact soil When compensatory root growth did not occur shoot growth was reduced. This resulted in there being a close relationship between total root length and leaf area. Further test results support a direct effect of mechanical impedance on shoot growth with a rapid (within 10 minutes) and large (50%) reduction in leaf elongation occurring when roots were mechanically impeded. In the field only plants whose roots were totally exposed to compact soil had reduced shoot growth with very compact subsoil having no effect.

ENGLISH ABSTRACT: The control of excessive vegetative growth is important in deciduous fruit orchards. Currently the plant growth regulator prohexadione-calcium (p-Ca) is used to control apple shoot growth in the Untited States of America and some European countries. The effect of P-Ca on the shoot and fruit growth of apples (Malus domestica B.), pears (Pyrus cummunis L.), plums (Prunus sa/icina L.) and nectarines (Prunus persica L.) was evaluated. Inhibition of shoot growth can effect fruit growth. Therefore I did a literature review on the fruit growth of pome- and stone fruit. Split pit, a physiological disorder associated with an increased fruit growth rate in stone fruit, was also investigated. During the course of the 2001 / 2002 season two trials were conducted in the Villiersdorp area of the Western Cape on 'Golden Delicious' and 'Granny Smith' apple trees. Single and multiple applications of P-Ca at different rates, with and without the surfactant Dash®, were applied. One of these trials was continued during the 2002 / 2003 season. In the 2001 / 2002 season, P-Ca reduced shoot growth in both trials on 'Golden Delicious'. The shoot growth of 'Granny Smith' was reduced in both trials where PCa was applied three or four times. There was an improvement in the fruit size of 'Golden Delicious' in both trials, but there was no improvement in the fruit size of 'Granny Smith'. In the 2002 / 2003 season, the single P-Ca application did not reduce shoot growth. Unfortunately 'Golden Delicious' was harvested before any data were obtained. Once again P-Ca had no effect on the fruit size of 'Granny Smith'. Dash® did not improve the effect ofP-Ca. In the 2002 / 2003 season we replicated one trial on five different pear cultivars in the Wolsely area of the Western Cape. Single and multiple applications of P-Ca at different rates were compared to a girdling treatment (2 weeks after full bloom). 'Early Bon Chretien', 'Rosemarie', 'Flamingo', 'Forelle' and 'Packham's Triumph' pear trees were used and Dash®was added to all 0f the treatments. P-Ca reduced shoot growth in all of the pear cultivars. Girdling reduced shoot growth only in 'Forelle'. P-Ca increased fruit set of 'Early Bon Chretien', 'Rosemarie' and 'Forelle', however, this was associated with a reduced fruit size of 'Early Bon Chretien' and 'Rosemarie'. Girdling did not increase fruit set, but increased fruit size of 'Flamingo' and 'Early Bon Chretien'. P-Ca reduced return bloom of 'Packham's Triumph' and 'Forelle', whereas girdling increased return bloom in all the cultivars except 'Packham's Triumph'. In the 2002 / 2003 season, trials were also conducted on 'Pioneer' and 'Songold' plums and 'May Glo' nectarine in the Wemmershoek and Stellenbosch area of the Western Cape. Single applications at different rates of P-Ca were applied. Dash® was added to all of the treatments. The higher rates of P-Ca reduced the shoot growth of 'Pioneer'. P-Ca only reduced shoot growth of 'Songold' initially and but did not reduce shoot growth of 'May Glo'. P-Ca had no influence on fruit size of 'Pioneer', 'Songold' or 'May Glo'. P-Ca did not aggravate the occurrence of split pit. In conclusion, P-Ca reduced shoot growth in apples and pears when applied at the appropriate rates. Although P-Ca reduced shoot growth of 'Pioneer' plum, more research needs to be done on stone fruit to optimise timing and rate of P-Ca applications.
AFRIKAANSE OPSOMMING: Die beheer van oormatige lootgroei is van kardinale belang in vrugtebome. Tans word die plantgroeireguleerder proheksadioon-kalsium (P-Ca) gebruik om die lootgroei van appels te beheer in die Verenigde State van Amerika en sekere lande in Europa. Die effek van P-Ca op lootgroei en vruggrootte is in proewe op appels (Malus domestica B.), pere (Pyrus cummunis L.), pruime (Prunus salicina L.) en nekatriens (Prunus persica L.) geëvalueer. Aangesien lootgroei inhibisie moontlik vruggroei kan vesnel, is 'n literatuurstudie oor die vruggroei van kern-en steenvrugte gedoen. Die ontwikkelling van gesplete pit by steenvrugte ('n fisiologiese defek geassosieer met versnelde vruggroei) is ook ondersoek. Gedurende die 2001 / 2002 seisoen is P-Ca in twee afsonderlike proewe in die Villiersdorp area van die Wes Kaap geëvalueer. Enkel en veelvuldige toedienings van verskeie konsentrasies P-Ca, met en sonder die benatter Dash", is op 'Golden Delicious' en 'Granny Smith' bome toegedien. Een proef is herhaal gedurende die 2002 / 2003 seisoen. In die 2001 /2002 seisoen het die P-Ca behandelings in beide proewe die lootgroei van 'Golden Delicious' verminder. Die lootgroei van 'Granny Smith' is in beide proewe verminder waar P-Ca 3 of 4 keer toegedien is. Die vruggrootte van 'Golden Delicious', maar nie 'Granny Smith' nie, is in beide proewe deur die P-Ca verbeter. In die 2002 / 2003 seisoen kon die enkeltoedienings van P-Ca nie die lootgroei verminder van 'Golden Delicious' of 'Granny Smith' nie. 'Golden Delicious' is geoes voor enige inligting oor die vruggrootte ingesamel kon word. Weereens het PCa geen invloed op die vruggrootte van 'Granny Smith' gehad nie. Dash® het nie die effek van P-Ca verbeter nie.In die 2002 / 2003 seisoen is proewe met P-Ca gedoen op 5 verskillende peer kultivars in die Wolsely area van die Wes Kaap. P-Ca is teen verskillende konsentrasies, met enkel en veelvuldige bespuitings toegedien en vergelyk met 'n ringelerings behandeling (2 weke na volblom). 'Early Bon Chretien', 'Rosemarie', 'Flamingo', 'Forelle' en 'Packham's Triumph' bome is gebruik en die benatter Dash® is by al die behandelings gevoeg P-Ca toedienings het lootgroei verminder in 'Early Bon Chretien', 'Rosemarie', 'Flamingo', 'Forelle' en 'Packham's Triumph'. Ringelering kon slegs die lootgroei van 'Forelle' verminder. P-Ca het die vrugset van 'Early Bon Chretien', 'Rosemarie'en 'Forelle' verhoog. Die toename in vrugset het gelei tot 'n afname in die vruggrootte van 'Early Bon Chretien' en 'Rosemarie'. Ringelering het die vruggrootte van 'Flamingo' en 'Early Bon Chretien' verbeter. P-Ca het 'n afname in die hoeveelheid reproduktiewe knoppe in die volgende seisoen, van 'Packham's Triumph' en 'Forelle' veroorsaak. Ringelering het 'n toename in die hoeveelheid vegetatiewe knoppe in die volgende seisoen gehad vir al die kultivars, behalwe 'Packham's Triumph'. Geduerende dieselfde seisoen is daar ook proewe gedoen op 'Pioneer' en 'Songold' pruime en 'May Glo' nektarienbome in onderskeidelik die Wemmershoek en Stellenbosch areas van die Wes Kaap. Bome is met enkel toedienings van verskillende konsentrasies P-Ca behandel en die benatter Dash® is by al die behandelings bygevoeg. Die hoër dosisse P-Ca het die lootgroei van 'Pioneer' verminder. P-Ca kon slegs die aanvanklike lootgroei op 'Songold' verminder en kon nie lootgroei van 'May Glo' beperk nie. P-Ca het geen invloed op die vruggrootte van 'Pioneer', 'Songold' of 'May Glo' gehad nie. P-Ca het nie die voorkoms van gesplete-pit vererger nie. Om saam te vat kan gesê word dat P-Ca lootgroei op appels en pere goed beperk teen die regte konsentrasies. Alhoewel P-Ca lootgroei suksesvol beheer het op 'Pioneer', moet daar meer werk gedoen word op steenvrugte.

Full text
Abstract:
Permafrost thawing could increase soil contaminant mobilization in the environment. Our objective was to quantify metal accumulation capacities for plant species and functional groups common to Alaskan military training ranges where elevated soil metal concentrations were likely to occur. Plant species across multiple military training range sites were collected. Metal content in shoots and roots was compared to soil metal concentrations to calculate bioconcentration and translocation factors. On average, grasses accumulated greater concentrations of Cr, Cu, Ni, Pb, Sb, and Zn relative to forbs or shrubs, and bioconcentrated greater concentrations of Ni and Pb. Shrubs bioconcentrated greater concentrations of Sb. Translocation to shoots was greatest among the forbs. Three native plants were identified as candidate species for use in metal phytostabilization applications. Elymus macrourus, a grass, bioconcentrated substantial concentrations of Cu, Pb, and Zn in roots with low translocation to shoots. Elaeagnus commutata, a shrub, bioconcentrated the greatest amounts of Sb, Ni, and Cr, with a low translocation factor. Solidago decumbens bio-concentrated the greatest amount of Sb among the forbs and translocated the least amount of metals. A combination of forb, shrub, and grass will likely enhance phytostabilization of heavy metals in interior Alaska soils through increased functional group diversity.

Solar radiation data is necessary for the design of solar heating systems and used to estimate the thermal performance of solar heating plants. Compared to global irradiance, the direct beam component shows much more variability in space and time. The global radiation split into beam and diffuse radiation on collector plane is important for the evaluation of the performance of different collector types and collector field designs.

Full text
Abstract:
This paper argues that, while most countries in Latin America and the Caribbean have managed to significantly improve the short-term efficiency of their infrastructure services since the widespread liberalization of the 1990s, they have been slow to ensure a fair distribution of the gains. They have also been slow in making the investments needed to ensure the prospects of future generations, including by protecting the environment for the long term. The paper places at least part of the blame on regulatory failures. It also shows how past mistakes can be corrected by the significant sectoral transformations, driven by new technologies, now underway. Digitalization is altering the economic characteristics of infrastructure services. Resulting changes in governance and financing options demand adjustments to economic regulations, including by broadening the regulatory toolkit to integrate new insights offered by developments in behavioral economics.
