　　为揭示滇重楼不同居群的表型多样性，为滇重楼种质资源的保护利用提供科学的理论依据。观测20个居群滇重楼15个性状的表型性状,采用变异系数、方差分析、主成分分析和聚类分析进行分析。滇重楼各表型性状变异丰富，变异系数在14.3%~46.2%之间，表型分化系数为52.13%，居群间和居群内变异相当。滇重楼显示出较高的多样(2.4415)，20个不同居群的平均多样性指数为2.2255~2.5363。主成分分析显示茎高、叶柄长、叶片长、宽、花瓣长，花萼长，花茎高是引起滇重楼不同居群间表型差异较大的因素。聚类分析表明，滇重楼20个居群可以分为3大类。滇重楼表型多样性较高，对其资源的保护和利用具有重要意义。

The aim was to reveal the phenotypic variation of Paris polyphylla. Smith var. yunnanensis in different populations and provide the scientific basis for the conservation and utilization. The phenotypic diversities of 15 traits from 20 populations of P polyphylla. Smith var. yunnanensis were observed. The results were analyzed by coefficient of variation, ANOVA analysis, principal component analysis and cluster analysis. The result showed that the phenotypic traits of P. polyphylla. Smith var. yunnanensis had rich variations. The coefficient of variation varied form 14.3% to 46.2% . The mean phenotypic differentiation coefficient was 53.13%, which indicating that the comparatively variation degree among or within populations P. polyphylla. Smith var. yunnanensis has a high phenotype diversity (2.4415), the mean phenotype diversity index of 20 populations ranged from 2.2255 to 2.5363. Principal components analysis indicated that the stem height, petiole length, leaf length and width, petal and calyx length, scape height were the main factors account for the phenotypic variations. According to the cluster analysis, the populations of P. polyphylla. Smith var. yunnanensis could be divided into three groups. There was abundant phenotypic diversity of P. polyphylla. Smith var. yunnanensis, which had important significance for its conservation and utilization.
