| Abstract | In this study, growth and osmolyte concentration in the leaves of halophyte, Sesuvium portulacastrum, were studied with respect to salinity. Therefore, the changes in shoot growth, leaf tissue water content, osmolyte concentration (proline content, glycine betaine) and antioxidant enzymes [polyphenol oxidase (PPO), superoxide dismutase (SOD) and catalase (CAT)] were investigated. The 30-day old S. portulacastrum plants were subjected to 100, 200, 300, 400, 500 and 600 mM NaCl for 28 days. The plant growth was steadily increased up to 500 mM NaCl stress at 28 days. TWC was higher in 300 mM NaCl treated leaves than that of 600 mM NaCl. Salinity stress induced the accumulation of osmolyte concentration when compared to control during the study period. The antioxidant enzymes PPO, CAT and SOD were increased under salinity. |
