Abstract:Imposition of NaCl-salinity stress induced oxidative reactions in root tissue of rice seedlings. A uniform accumulation of proline was marked with the increasing NaCl concentrations. Both peroxide content and lipid peroxidation level (MDA) increased with the salt treatment from the control. CAT, GPx and SOD activities decreased with the increasing NaCl concentrations suggesting a possible oxidative damage to root tissue.
Keywords:CAT  GPx  SOD  NaCl-salinity  Root            Oryza sativa L
