Abstract
Exogenous application of 10 μmol/L sodium nitroprusside (SNP), a nitric oxide (NO) donor, obviously counteracted the accumulation of malondialdehyde (MDA), a lipid peroxidation product in roots of rice seedling under salt stress, and significantly increased soluble protein content in roots of rice seedling. Meanwhile, the activities of ascorbate peroxidase (APX), peroxidase (POD) and superoxide dismutase (SOD) were induced in roots of rice seedling by 10 μmol/L SNP treatment under salt stress. However, the opposite effects of higher concentration of 50 μmol/L SNP were found. All these above indicated that exogenous lower concentration of NO could effectively attenuate the oxidative damage caused by salt stress, which was mainly achieved by means of enhancing anti-oxidative capability in roots of rice seedling.
