Fig. 2From: Abscisic acid mediated proline biosynthesis and antioxidant ability in roots of two different rice genotypes under hypoxic stressEffects of hypoxia on ABA and proline contents in the leaves (a, c) and roots (b, d) of both rice cultivars. DW represents dry weight. Data are the mean ± SE of three independent experiments.
