Activities of APX (a), MDHAR (b), DHAR (c), and GR (d) in salt sensitive and salt tolerant rice seedlings induced by exogenous proline and glycine betaine under salt stress. S₁₅₀ and S₃₀₀ indicate 150 mM NaCl and 300 mM NaCl, respectively. Pro and GB indicate 5 mM proline and glycine betaine spray, respectively. Mean (±SD) was calculated from three replicates for each treatment. Bars with different letters (small letters for BRRI dhan49 and capital letters for BRRI dhan54) are significantly different at P ≤ 0.05 applying DMRT.
