| 摘 要： | 目的：探讨不同半夏居群生理指标对高温胁迫的响应。方法：对不同半夏居群进行高温处理(35 ℃/25 ℃),测定其叶片中SOD活性、MDA含量、游离脯氨酸含量和根系活力。结果与结论：经高温处理后,各居群半夏SOD活性先增高后下降,与脯氨酸含量趋势相同,MDA含量持续升高,根系活力则显著下降。居群间对高温胁迫响应差异显著。 |

| Abstract: | OBJECTIVE: To study the effects of high temperature stress on the root vitality and leaf biochemical indexes in populations of Pinellia ternate. METHOD: The leaf activity of SOD, contents of MDA and free praline and root vitality were determined after a treatment of high temperature stress (35 degrees C/25 degrees C) was given to different populations of P. ternate. RESULT AND CONCLUSION: By stress time increasing, the leaf SOD and free praline rose firstly and then dropped, the content of MDA increased while the root ability decreased in all populations. And the response of populations of P. ternate to high temperature was significantly different. |
