Abstract
The effect of NaCl stress on protein content and antioxidant enzyme activity of Xylocarpus granatum was investigated. Salt stress was imposed on 60-days old plants with five different concentrations of NaCl (0, 50, 100, 150, 200 and 250 mM). NaCl induced significant differences in quantities of proteins. Nacl stress enhanced activities of SOD, CAT and POX. Further, in isoenzyme studies, 3 SOD isoenzymes (SOD1, SOD2 and SOD3), and 7 POX isoenzymes were detected with the treatment. Increase in antioxidant enzyme activity could be a response to an increased levels of free radicals induced by NaCl. This might have reduced the stress severity and allowing the plant to grow in a mangrove saline habitat.
