以2年生胶东卫矛为试验材料,清水为对照,研究了在低温胁迫下,不同浓度水杨酸处理胶东卫矛叶片中超氧化物歧化酶（SOD）、过氧化物酶（POD）及丙二醛（MDA）的含量和细胞膜透性的变化对抗寒性的影响,结果认为200 mg/L浓度的水杨酸处理的胶东卫矛叶片中POD的含量最高,MDA积累量最少,胶东卫矛的抗寒性最强。

이2년생효동위모위시험재료,청수위대조,연구료재저온협박하,불동농도수양산처리효동위모협편중초양화물기화매（SOD）、과양화물매（POD）급병이철（MDA）적함량화세포막투성적변화대항한성적영향,결과인위200 mg/L농도적수양산처리적효동위모협편중POD적함량최고,MDA적루량최소,효동위모적항한성최강。
Concentrations of SOD, POD and MDA in leaves and cell membrane permeability were studied with Euonymus di- autschovicus which could grow in low temperature as material in order to find the range of salicylic acid concentration on cold resistance of Euonymus diautschovicus and provided some theory basis for enhancing cold resistance of Euonyrnus diautschovicu. The results showed that cold resistance of Euonymu~ diautschovicus was the best under 200 mg/L salicylic acid condition.
