| 摘 要： | 研究不同生育时期干旱胁迫下马铃薯相关生理生化指标的变化，以期探讨干旱胁迫下马铃薯抗旱的生理机制。选取生产上推广的‘冀张薯8号’和‘夏波蒂’两个马铃薯品种，在旱棚内分区栽培。不同生育时期进行干旱处理，测定马铃薯超氧化物歧化酶（SOD）、丙二醛（MDA）、脯氨酸（Pro）的含量变化。结果表明，各生育时期干旱胁迫下，马铃薯MDA、Pro含量均增加，而SOD活性下降。花期干旱胁迫对马铃薯的生理生化指标影响最大；抗性强的品种MDA、脯氨酸含量增加的幅度较小，SOD的活力较高，而抗旱性弱的品种则相反。抗旱性强的品种在生理生化指标上具有抗旱的调节机制。 |

| Abstract: | The changes of the physiological and biochemical indices in different growth period under drought stress were researched in this paper to explore the drought-resistant physiological mechanisms of potato.The super oxide dismutase (SOD),malon dialdehyde (MDA) and Pro of the potato variety 'Jizhangshu8' and 'Shepody',which were extensively planted in production and planted inside different shed-houses under the condition of drought stress,were measured.The results showed that the content of malon dialdehyde (M... |
