摘  要：
以岷江百合(Lilium regaleWilson)的7个天然群体为研究对象,对其株高、花瓣长、叶片数、花朵数、叶片长和叶片宽等6个表型性状进行多样性分析。结果表明:岷江百合表型性状在群体间存在广泛变异,6个性状群体间的F值为4.87~34.91,达显著或极显著水平;群体内只有叶片长和叶片宽达极显著水平,其他4个性状均不显著。6个性状的平均表型分化系数(VST)为61.52%,群体间变异(26.25%)大于群体内变异(20.02%),说明群体间变异是百合表型性状的主要变异来源。岷江百合表型性状与地理因子的相关分析表明:株高、花朵数和叶宽与纬度成显著正相关,而其它性状与地理因子的相关性均不显著。利用群体间欧氏距离进行的UPGMA聚类分析结果表明,7个岷江百合天然群体可以划分为两类,说明性状的表型特征并没有依地理距离而聚类。

摘  要：
An experiment was conducted to analyze the phenotypic diversities in terms of 6 phenotypic traits(height of plant,length of petal,number of leaves,number of flowers,length of leaf and width of leaf)using 7 natural populations of Lilium regale Wilson.Analysis of variance for all traits showed that there were significant differences among populations.Among populations,the F value of 6 traits were from 4.87 to 34.91,except leaf was significantly different;Other traits were quite significantly different.Within population other traits were not significantly different except that length and width of leaf.The mean phenotypic differentiation coefficient VST of the 6 traits is 61.52%,and the variation among populations was higher than that within population,which indicated that the variance among populations was the main part of the phenotypic variation.The correlation analysis between the phenotypic traits of Lilium regale Wilson and geography factor showed that the correlation between them was not significant except that height of plant and the number of flowers and width of leaf significantly different positive affected by latitude.Seven natural populations of Lilium regale Wilson could be divided into 2 groups by UPGMA cluster analysis.Explaining the phenotypic traits didn't gather according to geography distance.
