Abstract
Cumaru is a tree originally from the Amazon. The objective was to analyze the parameters of gas exchange, relative water content, growth and biomass production in leaves and roots of Cumaru plants (Dipteryx odorata) submitted to drought. The experiment was conducted in a greenhouse at the Federal Rural University of Amazonia (UFRA), Belem-Para. The experimental design was completely randomized in split plot in time (four times evaluation and two water conditions: control and drought), with 5 repetitions, totaling 40 experimental units. Were applied Analysis of variance, standard deviations, statistical analyzes and the means were compared by Tukey test at 5% significance. Drought caused reduced in diameter, leaf biomass, transpiration, RWC at 7th day of treatment and increased stomatal resistance. The cumaru was not effective in retaining water in the system. The stomatal closure mechanism secured decreased transpiration in the plant loses less water, entertaining this mechanism also affect plant growth.
