Biochemical responses in young plants of castanheira-do-brasil (bertholletiaexcelsabonpl.) Submitted to drought

The Bertholletia excels known as castanheira-do-brasil, this species is very exploited of the Amazon, with great importance in generating employment and income in the region. The aim in this research was to evaluate the biochemical responses of the species Bertholletiaexcelsa in water stress conditions. The experimental design was completely randomized with two treatments: irrigated and non-irrigated plants, with 9 plants each, considering each plant as a repetition, and these repeated treatments in 3 times (0, 5 and 9 days), totaling 27 plants per treatment. The condition of water deficit for nine days adversely affected the concentration of starch and total soluble proteins. The condition of water deficit for nine days, on the contrary, increased the total soluble carbohydrate concentrations, total soluble amino acids, sucrose and proline.
