To investigate the effects of Cd and Cd-Sodium nitroproside (SNP) on growth and physiological parameters of Melia azedarach, this experiment was done in a completely randomized design in three replicates and arranged as factorial. Results showed the amounts of Cd and proline in the root of the plant significantly increased as Cd concentration in soil increased. Length and weight of roots decreased with increasing Cd in soil. Increasing cd concentration in soil did not affect the amounts of soluble sugar, relative water content and MDA. SNP compared to treatments without SNP increased the amount of fresh weight of root significantly. Since SNP did not affect almost none of growth the parameters in Melia azedarach, it was concluded that this compound did not play an important role in protection of the plant against heavy metal.
