Última Development of experimental structure and influence of high CO2 concentration in maize cro REA Silva,João B. Lopes da; Ferreira,Paulo A.; Pereira,Eduardo G.; Costa,Luís C.; Miranda,Glauco V.. Maize is a C4 plant that shows few or no response to high [CO2]. Thus, this study aimed to analyze the photosynthetic rate and yield of maize under high [CO2] and develop open-top chambers (OTC) to create an atmosphere enriched with CO2. The experiment was conducted between October 2008 and March 2009. The OTCs were developed in modular scheme. Measurement of photosynthetic rates, transpiration, stomata conductance, grain yield and dry matter were performed. The experimental design was randomized blocks with four replications and three treatments: P1 - plants grown in OTC with 700 ppm [CO2], P2 - plants grown in OTC with environmental [CO2], and P3 - control, cultivated in open field. The results were analyzed by ANOVA and Tukey's test (Pr< 0.05). The... Tipo: Info:eu-repo/semantics/article Palavras-chave: Open-top chambers; Climate change; Zea mays L.

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.
