| 摘 要： | 以不同的PEG-6000模拟干旱胁迫,采用10%、20%、30%的PEG处理剑麻幼苗,研究叶片质膜相对透性、丙二醛含量、游离脯氨酸含量以及保护酶SOD、POD活性的变化.结果表明,随着胁迫时间的延长和胁迫强度的增加,质膜相对透性呈现不断上升的趋势,脯氨酸出现大量积累的现象.两种保护酶的活性在胁迫初期反应较为缓慢,在胁迫处理一段时间后明显上升.从本研究可以看出,剑麻幼苗对干旱胁迫具有很强的适应性.

| Abstract: | Sisal seedling was used as experimental material and treated by different concentration of PEG-6000 to simulate the drought stress conditions.The PEG-6000 concentration was set as 10%,20% and 30%.The changes of the penetration of plasmalemma,the MDA content,the free proline content and the activity of SOD and POD were studied.The results showed that with the development of increase of treated time and stress intension,the penetration of plasmalemma rose gradually,while the proline accumulated.The activity o... |
