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、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。
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 there 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 colour, etc. There were significant or very significant correlation between the characters of flower diameter, anther length and the geographical factors （ longitude,latitude, elevation）. Accord- ing 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.
