The effects of sodium nitroprusside (SNP; nitric oxide donor) treatment on drought stress induced by PEG for different periods time in wheat seedlings were investigated. Our results suggested that 2, 4 and 6 d with 15 % could be termed as mild, moderate severe stress, respectively. Drought accumulation hydrogen peroxide resulted lipid peroxidation. On the other hand, activities SOD, CAT PAL increased under mild to counteract oxidative injury then decreased when became (6 d). As effect SNP treatment, 0.2 mM enhanced growth kept high relative water content alleviated damage. However, 2 aggravated a result uncontrolled generation reactive oxygen species ineffectiveness antioxidant systems.
