| 摘 要： | 人工控制条件下对宝兴鸭茅和金丝岭鸭茅的耐高温性能进行评价。结果表明随着胁迫温度的升高,鸭茅幼苗叶片的相对电导率和游离脯氨酸含量均呈上升趋势,超氧化物歧化酶（SOD）活性先上升后下降。对3项生理指标的分析表明两份鸭茅材料均具有一定的耐高温性能,该试验条件下宝兴鸭茅的耐高温性能略强于金丝岭鸭茅。

| Abstract: | The high temperature tolerance of two Dactylis glomerata materials, D. glom-erata cv. Baoxing and D. glomerata cv. 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. |
