Today, soil and water contamination with heavy metals, such as cadmium (Cd), have been one of the important challenges for environment and human and plant health. Application of plant growth regulators such as Salicylic acid (SA) have been the proper option for mitigation of Cd impact on plant growth. The objective of this study was to evaluate the interaction of Cd and SA on antioxidant enzyme activity, leaf soluble protein and malondialdehyde of Safflower (Carthamus tinctorius L. cv. Soffe). This experiment was carried out as factorial based on CRD with four replications. Treatments included of four levels of cadmium nitrate (0, 25, 50 and 100 mg kg-1soil) and three levels of foliar application of Salicylic acid (0, 0.5 and 1 mM). Results showed that interaction of Cd and SA was significant for protein contents, catalase, proxidas, polyphenol oxidas and superoxide dismutase activity and malondyaldehyd. Increasing of Cd levels significantly increased the malondyaldehyd, catalase, proxidas, polyphenol oxidas and superoxide dismutase activity, but SA application inversed this trends. SA mitigates the detrimental effects of Cd and improved the physiological response of safflower under Cd stress.
