Fig. 7From: Abscisic acid mediated proline biosynthesis and antioxidant ability in roots of two different rice genotypes under hypoxic stressEffects of exogenous ABA and ABA inhibitor on oxidative damage in both cultivars. The contents of MDA (a, b) and carbonyl groups (c, d) represent the lipid peroxidation and protein oxidation, respectively. DW represents dry weight. Data are the mean ± SE of three independent experiments. Different letters indicate significant differences at P < 0.05 using the least significant difference (LSD) testBack to article page
