摘要: 为了探明内蒙古草原多根葱抗旱性能,采用盆栽控水法研究干旱胁迫对多根葱植物叶片生理生化指标的影响。结果表明,随着干旱胁迫时间的延长,内蒙古草原3个样地(Ⅰ、Ⅱ、Ⅲ)多根葱叶片相对含水量呈显著下降的趋势,叶绿素含量、SOD、POD、CAT活性均呈先上升后下降的趋势,水分饱和亏、相对电导率、脯氨酸、丙二醛含量呈上升的趋势。多根葱干旱性程度与水分饱和亏、相对电导率、膜脂过氧化作用呈正相关,与叶绿素含量、相对含水量、保护性酶活性呈负相关。隶属函数法抗旱性综合评价耐旱性强弱顺序为Ⅰ > Ⅲ > Ⅱ。

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 > Ⅲ > Ⅱ.

Key words: Inner Mongolia steppe, Drought stress, Allium polyrhizum, Physiological change
