| 摘 要： | 以东方山羊豆及敖汉苜蓿为材料,研究低温胁迫对东方山羊豆和敖汉苜蓿可溶性蛋白含量、保护酶活性、渗透调节物质的影响.结果表明:在低温胁迫下,东方山羊豆及敖汉苜蓿脯氨酸含量、SOD、POD活性、可溶性蛋白含量先上升后下降.经对几项生理指标的综合分析,认为东方山羊豆比敖汉苜蓿具较强的抗低温能力.

| Abstract: | The seecUings of C-alega L and Medicago sativa CV. Aohan were used as experimental materials. Low temperature stress treatment to the seedlings was carried out, whereas the normal watering as control. The effects of low temperature stress on relative protective enzyme activity and the content of proline, soluble protein in the leaves of the two species were studied. The results showed that the low temperature stress treatment resulted in the activities of SOD and POD, the content of proline, soluble protein were increased and then declined. Through comprehensive analysis of these physiological and biochemical processes, it was concluded that the low temperature resistant ability of Galega L was better than that of Medicago sativa CV. Aohan. |
