ENZYMATIC AND NON-ENZYMATIC ANTIOXIDANT ACTIVITIES IN MAIZE (ZEA MAYS L.) UNDER SALT STRESS
The present study was carried out to determine the enzymatic antioxidants like superoxide dismutase
(SOD EC, 1.15.1.1), catalase (CAT EC, 1.11.1.6), peroxidase (POD EC, 1.11.1.7) and non-enzymatic antioxidants such as ascorbic acid and -tocopherol were analyzed in Zea mays L. in order to explore the
plants protective mechanism against reactive oxygen species under salt stress. These enzymes were examined
and analyzed in 45 days old plants exposed to various concentrations of 25mM-150mM NaCl. The NaCl stress
enhanced all the enzymatic and non-enzymatic antioxidant activities were augmented with increasing salinity
compared with respective control. The results suggest that maize plants may increase the activity of antioxidant
enzymes to have superior protection system against oxidative damage under NaCl stress.
