| 摘 要： | 结合数量统计方法对柠条锦鸡儿12个居群的12项形态特征进行了研究。结果表明：除小叶对数、叶形和荚果长外，其余形态性状在居群内或居群间都表现显著差异；以12个形态性状为基础的聚类分析将所研究的12个居群分为3类；主成分分析结果显示每荚种子、干粒重、托叶长和叶长等4个性状是造成柠条锦鸡儿表型差异的主要因素。 |

| Abstract: | By using the method of numerical statistics,morphological variation of Caragana korshinskii has been studied.Results show:inter-/intro-population variation occurred remarkably in most morphological characters except for numbers of leaf,leaf shape and pod length;based on the morphological characters,cluster analysis showed that,12 populations of Caragana korshinskii have been divided into 3 parts;principal component analysis showed that four characters including seeds per pod,1 000-seed mass,stipule length and leaf length are mainly factors which produced morphological variation of Caragana korshinskii. |
| Keywords: | Caragana korshinskii morphological variation populations |
