Última Leaf concentrations of nitrogen and phosphorus in phaseolus vulgaris l. Plants under high CO2 concentration and drought stress REA Silva,João B. L. da; Ferreira,Paulo A.; Justino,Flávio; Pires,Luanna C.; Toledo,Amanda S.. This study aims to evaluate the leaf concentration of nitrogen and phosphorus correlated to the production of photoassimilates in beans plants (Phaseolus vulgaris L.) under high [CO2] and drought stress. The experiment was conducted in Viçosa (Brazil), during the period from April to July 2009, by using open-top chambers equipped with CO2 injection system. The drought stress was applied, through the irrigation suspension, during the period from flowering to maturation. The experimental design was randomized blocks in split-plot scheme with four replication, where the plots with plants grown in [CO2] of 700 mg L-1 and [CO2] environment of 380 mg L-1 and the subplots with plants with and without drought stress. The results were submitted to ANOVA and Tukey... Tipo: Info:eu-repo/semantics/article Palavras-chave: Beans; Mineral nutrition; Photosynthesis; Climatic changes. Ano: 2014 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S0100-69162014000500012 Influences of two CO2 concentrations and water availability on bean crop REA Silva,João B. L. da; Ferreira,Paulo A.; Pires,Luanna C.; Pereira,Eduardo G.; Carneiro,José E. S.. This study was carried out to determine some physiological and phenological responses of the bean under high [CO2] and drought stress. The experiment was conducted from April to July 2009 in Viçosa, Brazil. The open-top chambers were used to enrich the air with CO2, whereas the drought stress was applied between the flowering and the ripening. The randomized block design was used, with four replicates in the subplots. The following plots were [CO2] at 700ppm (F1) and [CO2] environmental (F2) and the subplots were well watering (S1) and drought stress (S2). The results were subjected to Anova and the Tukey test (P < 0.05). For the treatments F1S1 and F1S2 the photosynthetic rate showed increments of 59% and the transpiration reduction of 12%. The yield,... Tipo: Info:eu-repo/semantics/article Palavras-chave: Photosynthesis; Phaseolus vulgaris L.; Climate changes.
