Effects of NaCl Stress on Antioxidative Enzymes of Glycine Soja sieb
Yan Li

The activity of anti-oxidant enzymes (Superoxide dismutase (SOD), Peroxidase (POD), Catalase (CAT) and parameters of oxidative stress malondialdehyde (MDA) of shoots were investigated in S. sieb naturally salt-resistant halophyte. The seedlings of S. sieb were treated with varying (0, 80, 160 and 240 mM) NaCl stress. The results showed that NaCl played an important role in growth of S. sieb. It made obviously promotion of certain NaCl concentration to growth of S. sieb, the seeflings of S. sieb grew best under 80 mM salt stress. MDA concentration of S. sieb obviously decreased under 80 mM salt stress then increased with salt concentration increased. The activities of SOD, POD and CAT increased with the increase of the concentration of NaCl in S. sieb. The salt tolerance of this halophyte under salt stress condition are probably due to its ability to exhibit high SOD, POD and CAT enzyme activities and Soluble Sugar (SS) concentration.
