In order to studied the effect of salt stress onantioxidant enzyme system and photosynthetic pigments in the leaves of Bush Cinquefoil (Potentilla fruticosa L.),and the correlation between the important physiological characteristics of salt tolerance. Bush Cinquefoil (Potentilla fruticosa L.) cutting seedlings was selected as the material, through watering NaCl and Na₂SO₄ solution of different concentration. The results showed that: with the constant enhancement of salt stress, SOD activity, chlorophyll content of Potentilla fruticosa L. leaves decreased; POD activity showed a rising trend; the carotenoid content decreased; the chlorophyll content of leaves was positive correlation with SOD, negatively correlated with POD, so SOD had certain protective effect on chlorophyll. Based on the analysis, Potentilla fruticosa L. has a certain tolerance to salt, suitable for planting in areas with low degree of salinization.
