We intented to establish how efficient the antioxidant responses of Viciafaba are against oxidative conditions resulting from drought stress under nitric oxide treatment. The drought stress induced by PEG for different periods of time in faba bean seedlings under sodium nitroprusside (SNP) treatment were investigated. The results suggested mild, moderate and severe stress were resulted from treatment for 2, 4 and 6 d with 15% PEG, respectively. Drought stress induced accumulation of hydrogen peroxide and resulted in lipid peroxidation. In addition, activities of SOD, CAT and PAL increased under mild stress to response the oxidative injury and then decreased when the stress came to severe.Under SNP treatment, 0.2 mM SNP enhanced faba bean seedlings growth and kept high relative water content and alleviated the oxidative damage. However, 2 mM SNP aggravated the stress as a result of uncontrolled generation of reactive oxygen species and ineffectiveness of antioxidant systems.
