Abstract:

Abstract: Influence on Anti-oxidation System and Na+、K+ content in were followed in plantlets in vitro of the cultivar Zihuabai under salt mixtures of NaCI and Na2SO4 in the ratio of 2: 1, 1: 1 and 1: 2 in molar concentration, which was further divided into the various concentrations of 0%, 0.15%, 0.30%, 0.45%, 0.60%, 0.75% and 0.90%, The results showed: Under salt mixtures stress, the change trend of SOD and POD activity are similarly. They were in a sudden increase at a certain concentration. Salt concentration had significant influence on SOD activity, POD activity. No interaction of salt concentration mixture was found for SOD activity, POD activity. The content of Na+ was significantly increased. But the content of K+ presents a gentle drop tendency. And Na+/K+ ratio increased significantly.
