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。
In this study, 15 varieties of Chrysanthemum germplasm collected from Jinling, Zhongshan and Yuhua families were used as experimental materials to compare the frost damage grades of petals and leaves and the numbers of foot buds in early spring , To evaluate its cold resistance, with a view to screening out cold hardiness, suitable for the application of the landrace chrysanthemum varieties in Northeast China. The results showed that the petals of the chrysanthemum varieties in the “Yuhua” series had the strongest cold resistance, the “Zhongshan” series was the second, and the “Jinling” series was the worst. The cold resistance of different series of chrysanthemum varieties was not significantly different. ’Yuhua’ series of ground chrysanthemums occurred in most of the early foot buds, higher than ’Zhongshan’ and ’Jinling’ series, ’Jinling’ series at least.
