干旱胁迫下甜菜碱对梨树生理指标的影响
Effect of Betaine on Physiological Indicators of Pear Tree under Drought Stress
摘要
Abstract
Three - year - old Niitaka pear trees were used to study the effects of exogenous betaine on some physiological indicators of pear under drought stress. The results showed that exogenous betaine had no significant effects on the proline content and soluble sugar accumulation in Niitaka pear leaves, but increased the SOD activity and decreased the MDA content and cell membrane permeability, so the drought resistance pear tree was improved.关键词
