Abstract

In order to evaluate the effect of selenium on the growth and yield of balangou under water stress, an experiment conducted as factorial in a randomized complete block design with four replications in Research Farm of the University of Mohaghegh Ardabili in 2018. The treatments consisted of 3 levels of water stress (irrigation at soil moisture drainage at 30, 60 and 90% moisture content of field capacity) and selenium treatment (0, 1 and 2 mg/l). Two week after the last treatment of selenium, the samples obtained for physiological and biochemical analyzes. The results showed that the interaction of water stress and selenium treatment had a significant effect on physiological and morphological traits. Plant height, plant dry weight, total chlorophyll and carotenoid in control plants significantly decreased with increasing water stress. The results of traits mean comparison showed that treatment with selenium at a concentration of 2 mg/l under water stress conditions at 60% moisture content increased the amount of chlorophyll a, chlorophyll b and total chlorophyll.
