ANTIOXIDANT ENZYMES ACTIVITY IN LEAVES OF NACL STRESSED C4 PLANT (ZEA MAYS L.)
The present study
was carried out to determine the antioxidant enzymes such as Superoxide
dismutase (SOD EC, 1.15.1.1), Peroxidase (POX EC, 1.11.1.7), Catalase (CAT EC,
1.11.1.6), Ascorbate peroxidase (APX EC, 1.11.1.11), Polyphenol oxidase (PPO EC,
1.10.3.1) were analyzed in Zea mays
L. in order to explore the plant’s protective mechanism against reactive oxygen
species under salt stress. The experiment was factorial based on completely
randomized block design with three replications. These enzymes were examined
and analyzed in 45 days old plants. The first 10 days of normal growth and 10
days of salt stress was applied. After salt treatment 7th day the
plants were analyzed in various concentrations of 0mM (control), 25mM, 50mM, 75mM
and 100mM NaCl. The NaCl stress enhanced all the antioxidant enzymes 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.
