Salicylic acid (SA, 100 and 200 microM) application under heavy metal (Pb2+ and Hg2+) stress conditions reduced the inhibitory effects of these metals on seed germination and seedling growth of two cultivars of rice (Oryza sativa L. cv Ratna and cv IR36). SA increased fresh and dry mass of shoots and roots in both cultivars under heavy metal stress. The higher concentration of SA (200 microM) was more effective, as evident from a better recovery from metal-induced growht inhibition. IR36 showed better tolerance and hence a better recovery capacity in comparison with Ratna. SA thus acted as a reliever of metal stress, which might be a function of SA in addition to its antipathogenicity effect
