Plant salt tolerance is usually correlated with more e fficient antioxi dant system. Plant has evolved protection mechanism that contains enzymatic reac tion system and no-enzymatic reaction system. The enzymatic reaction system main ly includes superoxide(SOD), catalase(CAT), ascorbate peroxidase(APX), peroxidox in (PRX), glutathione S-transferase(GST) and so on.
