Abstract: Salinity is an ecological factor of considerable important which is influences the plants growth. Salinity tolerance are importance to regulate defense mechanism which preventing the plant damages. The effect of NaCl treatments on specific activities of antioxidative enzyme in aquatic plant, Cryptocoryne elliptica cultures was determined. C. el/iptica cultures were treated with 0, 25, 50 and 100 mM of NaCl for 28 days in B5 solid medium. Catalase (CAT), ascorbate peroxidase (APx) and peroxidase (POD) specific activities were measured every 0, 1, 2, 7, 14 and 28 days of treatment periods. NaCl treatments initially induced CAT specific activities and decreased significantly (P<0.05) at the later stages of treatment periods. NaCl treatments did not significantly (P>0.05) affected the APx specific activities up to 14 days of treatment period. Longer treatment period significantly increased the APx specific activities of C. elliptica cultures.
