干旱胁迫对内蒙古草原多根葱生理生化指标的影响
Effects of Drought Stress on Physiological and Biochemical Parameters of Allium polyrhizum in Inner Mongolia
摘要
Abstract
In order to investigate the Allium polyrhizum drought resistances in Inner Mongolia,the method of potted control water,leaf physiological and biochemical characteristics of different drought stress were studied in this paper.The results showed that the leaf relative water content decreased significantly with the increasing extent of drought stress,chlorophyll contents,activities of superoxide dismutase (SOD),peroxidase (POD) and catalase (CAT) decreased after an initial increase,and water saturation deficit,relative electric conductivity,proline contents,malondialdehyde (MDA) increased.It was existed positive correlation between the drought resistance strength of Allium polyrhizum and the water saturation deficit,relative electric conductivity,membrane lipid peroxidation.It was existed negative correlation between the degree of drought and chlorophyll contents,relative water content,protection activity.With membership function method,the strength of the order of drought tolerance was Ⅰ ＞ Ⅱ ＞ Ⅲ.关键词
