Copper is an essential plant micronutrient, required for the protein components of several enzymes. Salicylic acid (SA) or orthohydroxy benzoic acid and other compounds which are belong to this group are plant phenolic that play a major role in regulation of many physiological processes e.g. growth, develoment , ion absorption and germination. In present research effect of different concentration of Copper sulfate (0,0/5,1,1/5 mM) and salicylic acid (5μM) on some physiological activities in two cultivar (Partov and Gohar) of mung bean (Vigna radiata L.) was studied, in hydroponic culture. The experiment was based on a completely randomized dosing with four replicates.We found that excess Copper, in both cultivar, cause a decrease in starch content of leaves in these plant. Proline, soluble sugar and Catalas activity enzyme was increased. Salicylic acid alleviated effect of excess Cu in leaves. We found that under cu stress Gohar is more resistant than partov cultivar.
