Figures & Tables

Effects of DA on activities of CAT, POD and SOD in leaves of bean plants under salt stress. Data presented are the means ± SD. Different letters indicate significant difference (p ≤ 0.05) among the treatments. CAT, catalase; DA, dopamine; POD, peroxidase; SOD, superoxide dismutase.

Effects of DA on IAA, ABA SA and proline content and K/Na ratio in leaves of bean plants under salt stress. Data presented are the means ± SD. Different letters on the bars indicate significant difference (p ≤ 0.05) between the treatments. ABA, abscisic acid; DA, dopamine; IAA, indole acetic acid; SA, salicylic acid.
