摘要：

Changes in growth, physiological and biochemical characteristics under salt stress with or without La3+ treatment in Saussurea involucrata Kar. et Kir. were investigated. The results showed that La3+ relieved the plant growth inhibition, improved the leaf water potential and water content, increased the soluble protein and the proline contents and decreased malondialdehyde content under salt stress. Further, addition of La3+ significantly increased the activities of superoxide dismutase, ascorbate peroxidase, catalase, and glutathione reductase, decreased the photosynthetic pigment decomposition and increased the ratio of total chlorophyll to carotenoids under salt stress.
