干旱胁迫对大豆生理指标的影响
Influence of Drought Stress on Soybean Physiological Indexes
摘要
Abstract
To investigate the drought resistance of soybean varieties, stress coefficient analysis and grey related correlation analysis were introduced into this experiment, which can identify the drought resistance of all the test varieties and provide the basis for the drought screening. Results showed that under drought stress, with the time of drought stress exterding the relative water content of leaves(RWC) decreased in 12 varieties, while the content of soluble sugar( WSS), free proline (Pro) and malondialdehyde (MDA) content increasd gradually, especially the peroxidase (POD) activity in most soybean cultivars exhibited up trends. Divided all tested varieties into 3 groups, Heinong56, Ha5489, Heinong59 exhibited high drought resistance and the grey correlation grade ( ri ) ＞ 0. 7737; Suinong28, Hefeng55, M3, Heinong46, Heinong50, Heinong44 were moderately resistant (0.7720 ＜ ri ＜ 0. 7488); Fengshou24, M2, M1 were lowly resistant (0.7453 ＜ ri ＜ 0.7359).关键词
