| Abstract: | Effects of salicylic acid （SA） on germination of seeds and growth of seedlings of Pinus Yunnanensis studied, The results showed that, teated with lmg/L of SA, germination percentage were promoted; Treated with 0. 001 - 0.01mg/L of SA, the system of root activity and the weight of the fresh plant were increased;The radicle length and plant heigh were all higher that those of the control, the activity of peroxidase（POD） and superoxide dismutase （SOD） were remarkably increased . Among those of the control, 0. 001mg/L of SA effect on Pinus Yunnanensis was the best. |
