Effect of different magnitude of PEG induced imbibitional dehydration stress (− 0.344, − 0.851 and − 1.619 MPa) on the accumulation of superoxide (a), and hydrogen peroxide (b); protein oxidation [assessed in terms of free carbonyl content (c)] and membrane lipid peroxidation [assessed in terms of accumulation of thiobarbituric acid reactive substances (d)] of four indigenous aromatic rice varieties of Oryza sativa L. (Tulaipanji, Sitabhog, Badshabhog and Jamainadu). Results are mean of three replicates ± standard error. *Significant from control at 0.05 level (t test). **Significant from control at 0.01 level (t test)
