To evaluate the exogenous SA-induced germination, biochemical and developmental alterations, different concentrations (10, 100, 500 and 1000 ¦ÌM) of SA were applied to rye (Secale cereale L.) seeds in hydroponic culture conditions for 15 days. The observations revealed that seed germination and root elongation were stimulated in 10 ¦ÌM SA treatment, however they were inhibited in higher concentrations (100 and 500 ¦ÌM) of SA. Furthermore, there was no germination in 1000 ¦ÌM SA. The analysis of antioxidant enzymes revealed that although superoxide dismutase activity increased, catalase activity decreased in comparison to control. Besides, lipid peroxidation and peroxidase activity increased in 10 ¦ÌM SA, whereas they decreased in higher concentrations. Similarly total chlorophyll content increased in 10 ¦ÌM SA, but it decreased in 100 and 500 ¦ÌM SA treatments. Moreover anthocyanins and carotenoids increased after SA treatment.
