Efficiency of pretreatment as foliar spray of indole-3-acetic acid, gibberellic acid and kinetin, each ranging from 0.1 to 10.0 μM concentration, in restoring the metabolic alterations imposed by NaCl salinity was investigated in Vigna radiata (L.) Wilczek. Glycolate oxidase, superoxide dismutase, catalase and peroxidase activities increased under stress in leaves and roots also. Malondialdehyde content and total peroxide content also increased under stress. All the three hormones used were able to overcome to variable extents the adverse effects of stress imposed by NaCl to these parameters.

Keywords: catalase; glycolate oxidase; malondialdehyde; peroxidase; peroxide; superoxide dismutase
Subjects: auxins; catalase; cytokinins; gibberellins; glycolate oxidase; malondialdehyde; mung bean, salt stress, growth regulators; peroxidase; salt stress alleviation, growth regulators; superoxide dismutase; Vigna radiata
