英文摘要	The study was conducted to investigate the influence of the exogenous salicylic acid (SA) on the physiological and membrane damage in Rhodiola algida seedlings under low temperature stress. With Rhodiola algida seeding as experimental material to study the effects of exogenous SA on three antioxidant enzyme activities (CAT, SOD, POD), malondialdehyde (MDA) content and membrane damage of Rhodiola algida seeding under low temperature of 0 degrees C. The results showed: under the condition of 0 degrees C low temperature stress, Rhodiola algida seedlings leaves, treated with exogenous SA, the activities of antioxidative enzymes such as catalase (CAT), peroxidase (POD) superoxide dismutase (SOD) increased in different degrees compared with the control. However, the content ofMDA decreased significantly. Ca2+-ATP and Mg2+-ATP enzyme activity of claloroplast membrane had been enhanced in different degrees. Exogenous SA reducing the membrane lipid oxidation product of MDA by increasing antioxidant enzyme activity and anti-oxidising substance content; and reduced the damage of cell membranes, resulted in improving the tolerance of Rhodiola algida seedlings to chilling stress by enhancing Ca2+-ATP and Mg2+-AIT enzyme activity of chloroplast membrane; concentration of exogenous substances SA that improved cold tolerance of Rhodiola algida was 0.1-0.3 mg/l, and the optimum concentration was 0.3 mg/l.
