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.
