RESUMO:

The objective of the work was to evaluate the ecophysiological and biochemical parameters in corn (Zea mays) plants submitted to water deficiency in different concentrations of brassinosteroids and azospirillum. The experiment was carried out in a vegetable house, which belongs to the Federal Rural University of the Amazon (UFRA), from December 2019 to January 2020, using corn plants. Before sowing, part of the corn seeds were inoculated with Azospirillum and part was not. Brassinosteroids (0, 0.3 and 0.6 μM Br) were applied fifteen and thirty days after planting. Ten days after the last application of epnobrassinolide, stress was applied to the treatments that would receive the stress. Seven days after the application of water deficiency to corn plants, they were collected for biochemical analysis, being separated into leaf and root. Evaluations related to ecophysiological characteristics, carbon metabolism and nitrogen metabolism were carried out. Thus, it is expected to observe whether the brassinosteroid contributes as an attenuator of water stress, as well as whether azospirillum improves nitrogen assimilation favoring corn metabolism. In addition to changes in the nitrogen metabolism of corn due to the attenuating action of brassinosteroids and azospirillum in relation to water deficiency. The data are being tabulated and analyzed, so they are not being presented.
