Özet

In this study affects nitric oxide on the activities of antioxidant enzymes (superoxide dismutase and peroxidase), hydrogen peroxide (H2O2) and superoxide anion (O2.-) contents, lipid peroxidation level on the leaves of maize (Zea mays L.) were investigated. According to planting day, sodium nitroprusside (SNP), (a donor NO) concentrations of 0.0, 0.1, 1, and 100 μM were applied by spraying on the plant leaves on the 10th day and 14 days plants were harvested. H2O2, O2 .- and lipid peroxidation levels reduced by application SNP concentration compared to the control. At the same time, SNP concentrations also increased the activities of antioxidant enzymes such as SOD, POD.
