干旱胁迫对春大豆叶绿素含量和根系活力的影响
Effect of Drought Stress on Chlorophyll Content and Root Activity of Spring Soybean
摘要
Abstract
In order to research the effect of drought stress on soybean physiological property,chlorophyll content,root activity and root relative water content of three spring soybean varieties with different drought resistance were determined under drought stress. The results showed that chlorophyll content and root relative water content decreased significantly with the increase of drought stress,the root activity was seedling >flowering >pod-setting >seed-filling,the root relative water content was seed-filling > pod-setting >flowering > seedling. The chlorophyll content in seedling and root activity in seedling,flowering,pod-setting were Heinong 57 > Gailiang 168 > Suinong 26 under drought stress. The root relative water content was Heinong 57 > Cailiang 168 > Suinong 26 under moderate drought stress. Under field moisture capacity of 30%-75% ,root relative water content significant positively correlated with chlorophyll content,while significant negatively correlated with root activity.关键词
