Jinsiling, was evaluated under artificial con-ditions. The relative conductance rate, free proline content and SOD activity in seedling leaves was detected. Results showed that with the increase of temperature, the relative conductance rate and free proline content increased in both two materi-als, while the activity of SOD increased first and then decreased, indicating that the two materials had heat-resistant mechanism. D. glomerata cv. Baoxing presented slightly higher resistance against high temperature under experimental conditions compared with D. glomerata cv. Jinsiling.展开更多
