SUMMARY:
The growing demand for the acai fruit has increased the management of this plant in terra firme areas. Being a species with high water demand, management requires an adequate irrigation system. However, the actual water demand required by the plant is still unknown, due to the little study on the species, which ends up making production more expensive. Thus, this work aims to evaluate the physiological and biochemical changes in young plants of three genotypes of Euterpe oleraceae submitted to hydrical stress. Thus, three genotypes of the species will be evaluated: one from Anajás-PA, the BRS-PA cultivar and the new BRS-Ver-o-peso cultivar for physiological analyzes such as: gas exchange - CO2 assimilation rate (PN ), stomatal conductance (gs), perspiration (E), intercellular concentration of CO2 (Ci); and biochemical, in the determination of carbohydrate profile, free amino acids, oxidizing compounds and antioxidant enzymes. With this, it will be observed if the new cultivar has greater tolerance to water stress than the others. These analyzes will be evaluated under two water regimes (irrigated and non-irrigated). Data will be analyzed by analysis of variance, and means will be compared by Tukey test at 5% probability.
