Abstract

The experiment was applied in the green houses of the College of Agriculture, University of Wasit, Iraq. The study aimed to investigate the effect of interactions between some amino acids and salt stress in stimulating some antioxidants of Capsicum annuum. The experiment was applied according to a randomized complete block design (RCBD) with three replicates. The averages were compared using the least significant difference (LSD) with 0.05 probabilities. The experiment included six treatments, which were combinations of river water, drainage water (5 dSm-1) and amino acids (tryptophan and arginine at a concentration of 50 and 100 ppm). The results showed that the superiority of treatment T3 (treatment of river water and amino acids 100 ppm) in the vegetative growth characteristics represented by plant height (30.97) cm, leaf area (24.33) cm2, chlorophyll percentage in leaves (64.93) and dry weight (14.33) g. Antioxidant enzymes (Catalase and Peroxidase) increased in T4 treatment (5 dSm-1).
