1. Produtividade da água em biomassa e energia para 24 variedades de cana-de-açucar / Water productivity in biomass and energy for 24 sugarcane varieties
The purpose of this study was to observe the response on biomass yield and energy (shoot) as well as the water productivity (WP) for 24 sugarcane varieties, subjected to full and deficit irrigation during stalk growth stage. Two experiments were established under greenhouse conditions on Biosystems Engineering Department, ESALQ/USP, Piracicaba, SP. The Exper

2. 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

3. 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

4. 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

5. 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

6. Photosynthesis and Carbon Partitioning in Transgenic Tobacco Plants Deficient in Leaf Cytosolic Pyruvate Kinase1
Whole-plant diurnal C exchange analysis provided a noninvasive estimation of daily net C gain in transgenic tobacco (Nicotiana tabacum L.) plants deficient in leaf cytosolic pyruvate kinase (PKc−). PKc− plants cultivated under a low light intensity (100 μmol m−2 s−1) were previously shown to exhibit markedly reduced root growth, as well as delayed s
