摘要/Abstract

摘要： 对新疆天山地区5个弯刺蔷薇（Rosa beggeriana）居群进行叶片、果实、种子等11个表型性状的多样性分析。结果表明：弯刺蔷薇各表型性状在居群间和居群内均表现出极显著差异。居群间的表型分化系数（V_ST）为35.76%，远低于居群内的64.24%，说明居群内的变异是表型多样性的主要来源。各表型性状的平均变异系数（CV）为14.78%，性状离散程度较低；果实和种子性状的变异是造成弯刺蔷薇表型变异的主要因素。相关性分析发现，弯刺蔷薇部分营养生长与生殖生长性状存在相关关系；果长与其居群所处地理经度呈显著正相关，单果种子数与海拔高度呈极显著负相关。表型性状聚类结果表明，5个居群划分为4类，各居群之间没有严格按地理距离而聚类。

Abstract: Five populations of Rosa beggeriana in Tianshan Mountains of Xinjiang were selected to analyze the phenotypic diversity based on 11 phenotypic traits from leaves，fruits and seeds. The results showed there were highly significant differences in phenotypic traits among and within populations. The mean phenotypic differentiation coefficient（VST）among populations was 35.76%，less than that of within populations（64.24%），which indicated that the phenotypic variation mainly occurred within populations. The average variation coefficient（CV）of phenotype traits with 14.78% showed that there was low variation of phenotypic traits in Rosa beggeriana populations. Traits on fruits and seeds were the main factors account for phenotypic variations. Correlation analysis showed that there were the correlations between vegetative and reproductive traits. Length of fruit showed a significant positive correlation with the longitude，and the numbers of seeds per fruit showed a highly significant negative correlation with the altitude. The cluster analysis on the phenotypic traits showed 5 populations were divided into 4 groups，which the populations did not strictly classify according to the geography distance.
