1. Plant growth analysis and seed vigor expression: effects of soil waterlogging during rye plant development
This study aimed to evaluate the growth, assimilate partitioning and seed vigor expression of rye seeds subjected to waterlogging during development. The experimental design was completely randomized with six replications and three treatments. The treatments involved different waterlogging periods: a) no waterlogging; b) single waterlogging of three days; an

3. Physiological response of oil palm interspecific hybrids (Elaeis oleifera H.B.K. Cortes versus Elaeis guineensis Jacq.) to water deficit
Water supply is the main yield-limiting abiotic factor of oil palm in Colombia. To determine the effect of water deficit on the physiology of oil palm and to assess the tolerance degree to this condition, interspecific Elaeis oleifera versus Elaeis guineensis 'U1273', 'U1859', 'U1914', and 'U1937' hybrids were planted for 60 days in soil with different water

4. Growth Reduction effects of Paclobutrazol Applied at Different Cacao Seedling Stages.
The effects of paclobutrazol on the morphological and growth characteristics of caco (Theobroma cacao L.) seedlings were evaluated. The experiment was arranged in four randomized blocks in a split-plot lay-out. Main plots were assigned to growth stages (mature cotyledonary leaves, first, second and third flushes) and sub-plots to paclobutrazol dosages (0,30,

5. Crescimento, fotossíntese e partição de assimilados em genótipos de arroz irrigado / Growth, photosynthesis and assimilate partitioning of irrigated rice genotypes
xii In this study, photosynthetic characteristics of irrigated rice (Oryza sativa L.) genotypes were evaluated. It were also evaluated with relation to growth and assimilates partitioning characteristics rice cultivars differing in yield potential, BRS Pelota (higher yield) and BRS Firmeza (lower yield). No correlation between maximum efficiency of PS2 photo

6. PLANT DENSITY AND PRUNING IN THE DRY MATTER PARTITIONING OF HYDROPONICALLY CULTIVATED POTATO / DENSIDADE DE PLANTIO E PODA DA PARTE AÉREA NA PARTIÇÃO DE MASSA SECA DE PLANTAS DE BATATA EM HIDROPONIA
Hydroponic system is an important improvement of the potato production process of tuber seeds. There is no enough information about management techniques of hydroponically cultivated potato. A main problem of this production system is the excessive shoot growth, which results in a low propagation rate. Planting density and pruning may change the relationship

7. Variabilidade genética de acessos de tomateiro (Lycopersicon esculentum Mill.) com base na avaliação de fotossíntese, partição de fotoassimilados e produção / Genetic variability of tomato (Lycopersicon esculentum Mill.) accesses on the basis of the evaluation of the photosynthesis, partition of photoassimilates and production
The genetic variability of nine accesses of tomato (Lycopersicon esculentum Mill.) of indeterminate type, of the Vegetable Germplasm Bank of the Viçosa Federal University was evaluated for photosynthetic capacity (A), dry matter, partitioning dry matter and yield, having been used as standard of the cultivating tomato the Santa Clara cultivar. The experimen

8. Crescimento, metabolismo do carbono e partição de assimilados, em resposta à manipulação da razão fonte:dreno, em Coffea arabica L. sob condições de campo / Growth, carbon metabolism and assimilate partitioning in response to source:sink manipulation in field-grown Coffea arabica L. trees
Alterações no crescimento vegetativo, nas trocas gasosas, nos parâmetros de fluorescência da clorofila a, no metabolismo de carboidratos e no particionamento do 14carbono, em resposta à manipulação da relação fonte:dreno, foram investigadas em plantas de café cultivadas em campo. Essas manipulações foram realizadas por meio de desfrutificação e

9. Regulation of Assimilate Partitioning in Soybean 1: Initial Effects following Change in Nitrate Supply
Increased concentrations of nitrate in a nutrient solution (2, 5, and 10 millimolar KNO3) were correlated with increased shoot:root ratios of non-nodulated soybeans (Glycine max [L.] Merr.) grown in sand culture. While altering the pattern of C and N partitioning, the N treatments did not affect whole plant photosynthesis over the study period. To determine

10. Effect of Shading Individual Soybean Reproductive Structures on Their Abscisic Acid Content, Metabolism, and Partitioning 1
Pod set in soybean is related to carbon partitioning and may be, at least partially, regulated by abscisic acid (ABA) concentrations. The studies reported here examine the relationship between carbon and ABA partitioning, reproductive abscission and ABA metabolism. The partitioning of radiolabeled ABA and photoassimilates from leaves to flowers and endogenou

11. Photoperiodic and Genetic Control of Carbon Partitioning in Peas and Its Relationship to Apical Senescence 1
Apical senescence but not flower initiation is delayed by short days (SD) compared to long days (LD) in pea plants (Pisum sativum L.) of genotype E Sn Hr. We recently reported that delay of senescence correlated with slower reproductive development, suggesting that fruits are weaker sinks for assimilates under delayed senescence conditions. Thus, we have exa

12. Regulation of Photosynthetic Carbon Metabolism in Cucumber by Light Intensity and Photosynthetic Period 1
The effects of photosynthetic periods and light intensity on cucumber (Cucumis sativus L.) carbon exchange rates and photoassimilate partitioning were determined in relation to the activities of galactinol synthase and sucrose-phosphate synthase. Carbon assimilation and partitioning appeared to be controlled by different mechanisms. Carbon exchange rates wer
