1 山丹不同居群花器官的形态多样性研究 1 2 刘冬云 , 刘燕 1 2 （河北农业大学 园林与旅游学院,保定071000；北京林业大学园林学院国家花卉工程技术研究中心,北京100083） 摘要 ：为掌握山丹种质资源花器官的多样性，对国内山丹资源进行引种种植观测。结果表明，25 个山丹居 群的花器官性状表现出一定差异。差异主要来源于花蕾毛的有无、花瓣宽、反卷度及花色等性状，其中花朵直 径与花药长与地理因子（经度、纬度、海拔）存在显著或极显著相关性 ；根据主要花器官性状对25 个居群进行 类平均UPGMA 聚类，可以分为5 类，结果表明山丹居群花器官性状的聚类与地理位置及海拔都有一定的关系。 关键词 ：山丹; 种质资源; 花器官; 居群; 多样性 Study on the Floral Diversity of the Different populations of Lilium pumilum DC. 1 2 LIU Dong-Yun LIU Yan 1 （College of Gardens and Tourism, Agricultural University of Hebei, Baoding, 071000; 2 College of Landscape Architecture, Beijing Forestry University, National Floriculture Engineering Research Center, Beijing 100083） Abstract ：In order to investigate the floral diversity of germplasm resources of L.pumilum, domestic resources of L.pumilum were planted and observed. The results showed that here were certain discrepancies among twenty five L.pumilum populations. The discrepancies were mainly concerned with those flowers With or without hair bud, petals wide, anti-curl of petals and flower color, etc. There were significant or very significant correlation between the characters of flower diameter, anther length and the geographical factors （longitude, latitude, elevation ）. According to the main floral traits of 25 populations L.pumilum, it can be clustered into 5 groups. The geographical location and altitude were correlated with clusters based on floral traits.
