| 摘 要： | 以野生樱桃李的8个天然群体为研究对象,对7个表型性状进行多样性分析。研究发现,野生樱桃李的表型性状在群体间和群体内均存在极其丰富的变异,且大多变异极显著;通过欧氏距离进行的UPGMA聚类分析将8个天然群体分为2组,主成分分析和方差分析结果显示枝条长度、枝条粗度、叶片长度和叶柄长度4个表型变异最大,生态环境是造成野生樱桃李表型差异的主要因素。 |

| Abstract: | The aim of this text was mainly to analyze the phenotypic diversity of natural populations of Prunus divaricata Ldb.and the 7 morphological traits.The results indicated that there were extremely rich variations of phenotypic traits between populations and within populations of Prunus divaricata Ldb.Based on the morphological characters,cluster analysis showed that 8 populations of Prunus divaricata Ldb.have been divided into 2 parts.Principal component analysis and analysis of variance showed that four char... |
