Abstract
Antioxidant parameters were studied under salt stress in shoots and roots of two wheat cultivars PBW 343 (drought sensitive) and C 306 (drought tolerant). Compared to C 306, PBW 343 showed higher activities of monodehydro-ascorbate reductase, glutathione-S-transferase, glutathione peroxidase in shoots and roots and higher levels of redox state of glutathione in roots under salt stress, but it also showed large increases in oxidative toxicity in terms of protein carbonyls and lower levels of nitric oxides in shoots and roots. Almost no increase in protein carbonyls accompanied with absence of increases in antioxidants under salt stress in C 306 indicated the presence of different antioxidants under salt stress in C 306.
