摘　　要：目的:通过对不同产地冬凌草的生态特征进行比较,探讨冬凌草种质资源的多样性,为其新品种的选育提供依据。方法:对不同产地的冬凌草进行观察描述,比较不同产地冬凌草的叶片形状、叶缘形状、叶面特征、叶背、叶脉、叶毛、茎色、茎绒毛、叶片大小、分枝数等之间的差异性。结果:不同产地冬凌草的生物学性状呈现明显差异。结论:不同产地冬凌草的生物学性状呈现不同差异,证明冬凌草种质资源较为丰富。Objective：To explore the diversity of germptasm resources, and to provide the basis for breeding new varieties through com- parison of ecological characteristics of different origin of Rabdosia rubescens. Methods： Observed and descripted of different origin of the Rabdosia rubescens, and compared the differences of different origin of Rabdosia rubescens leaf shape, leaf margin shape, leaf surface characteristics, leaf back,leaf vein,leaf back,leaf hair, stem color, stem villi, leaf size, number of branches. Results ： Biological charac- ters of different origin of Rabd0sia rubescens showed significant difference. Conclusion： Biological characters of different origin of Rabdo- sia rubescens present different differences, and which prove Rabdosia rubescens germplasm resources are abundant.
