- Abstract
The objective of this study was to evaluate gas exchange and phytomass accumulation of sesame genotypes under different strategies for the use of saline water. The research was conducted in a greenhouse, in a randomized block design in a 6 x 2 factorial arrangement, with six strategies for the use of saline water applied in the different phenological phases of the plants (SE - irrigation with low salinity water throughout the cultivation cycle; VE - irrigation with high salinity water in the vegetative phase; FL - in the flowering phase; FR - in the fruiting phase; VE/FL - in the vegetative/flowering phase; VE/FR - in the phases vegetative/fruiting) and two sesame genotypes (BRS Seda and BRS Anahí), with four replicates. Water with high salinity (2.7 dS m-1) was used, alternating with water with low salt concentration (0.3 dS m-1), at different stages of the crop cycle. Irrigation with water of 2.7 dS m-1 during the flowering phase, and in the vegetative/flowering phases, did not compromise the stomatal conductance, transpiration and CO2 assimilation rate of sesame genotypes. The water salinity of 2.7 dS m-1 applied in the vegetative/flowering phases impaired the accumulation of phytomass by sesame plants.
