为更深入了解干旱胁迫下金边瑞香生长发育的特征,通过盆栽控水方法对苗木叶片丙二醛（MDA）含量和超氧化物歧化酶（SOD）进行测定,探究了干旱胁迫对金边瑞香幼苗生理特性的影响。结果表明：通过干旱胁迫金边瑞香幼苗丙二醛（MDA）呈先上升后下降;超氧化物歧化酶（SOD）呈下降趋势。

To deeper understand the growth characteristics of Daphne odora var.marginata Mak.under drought,the effects of drought stress on the physiological characteristics of Daphne odora var.marginata Mak.leaves were studied.The content of malondialdehyde（MDA）and the activities of SOD were studied by pot experiment with controlled irrigation.The result showed that the content of MDA increased at beginning and declined later with the degree of drought stress aggravated,and the activitie of SOD declined.
