摘要：北京地处华北暖温带地区，其寒冷的冬季限制了常绿阔叶植物的正常生长，因而在漫长的冬季城市景观萧条，缺乏生机勃勃的绿色。目前，北京园林中已经引种的常绿阔叶植物有20多种，得到较普遍应用的则为数甚少。由于北京特殊的气候条件，限制植物越冬的环境因子比较复杂，导致引种工作的盲目性和较低的引种成功率。
Euonymus evergreen hybrid（ 1#, 2#, 3#） and their parents （Euonymus japonicus‘ Zhuzi＇ , E. kiautscho- vicus） were studied to test whether their cold resistance were stronger than their parents in the winter. The result showed The semi-lethal temperatures （LT50） were assessed separately by electrolyte leakage, the result showed that the LT50 of 1#, 2#, 3#, E. japonicus＇ Zhuzi＇ and E. kiautschovicus were 36℃ , 32. ICE , -28.5℃ , -26.9℃ , and -28℃ respectively. The activities of superoxide dismutase （SOD）, peroxidase （POD） in 3# were higher than that of the others, but there was no significant difference among the other varieties. The contents of proline in leaves of E. japonicus＇ Zhuzi＇ were higher than that of Euonymus evergreen hybrids and E. kiautschovicus. The present study indicates that the hybrid evergreen euonymus and their parents had different mechanisms of cold-resistance.
