Abstract

The environmental effects are based on factors prevalent in plant development, since they determine the conditions for sustaining life. Therefore, the objective was to evaluate the ecophysiological behavior of early stage of maize and cowpea in different culture environments: greenhouse with greenhouse transparency of 50% and the external environment in the field. The experiment was conducted during September to November 2008; it was conducted in an area of the meteorological station of the Federal University of Ceará, using a randomized design in a 2x2 factorial design with four replications. The variables evaluated in both culture environments were: wind speed (U), global photosynthetically active radiation (PAR), internal CO2 concentration, transpiration, stomatal conductance, and rate of photosynthesis. The results were submitted to analysis of variance (ANOVA) and comparison of means by Tukey test in both experiments. It was concluded that the values of wind speed and global photosynthetically active radiation inside the greenhouse were always lower than the values obtained in the external environment. There were changes both morphological and physiological for both cultures studied.
