摘　　要：以‘金陵’、‘钟山’和‘雨花’系列的15个地被菊品种为试材,比较研究了各品种地被菊的花瓣和叶片的冻害级数及其早春发生的脚芽数量,对其抗寒性进行评价,以期筛选出抗寒性强、适合东北地区应用的地被菊品种。结果表明:‘雨花’系列地被菊品种花瓣的抗寒性最强,‘钟山’系列次之,‘金陵’系列最差;不同系列地被菊品种叶片的抗寒性无明显差异;‘雨花’系列地被菊早春发生的脚芽最多,高于‘钟山’和‘金陵’系列,‘金陵’系列最少。Taking ＇Jinling＇ ,＇ Zhongshan; and ＇ Yuhua＇ series of 15 Dendrantherna morifolium varieties as materials, series of freezing injury of the petals and leaves of Dendranthema morifolium ,the recovery number of emergent rhizomes were compared and studied,and the cold hardiness was evaluated,in order to screen out the cold hardiness and suitable for the northeast area the application of Dendranthema morifolium. The results showed that the strongest cold hardiness of petals was the varieties ＇Yuhua＇ ,then the ＇Zhongshan＇ and the ＇Jinling＇ was worst. There was no difference in the cold hardiness of leaves among them. The number of the emergent rhizomes of the varieties ＇Yuhua＇ was the most than the varieties ＇Zhongshan＇ and ＇Jinling＇ ,which of the varieties ＇Jinling＇ was the lest.
