摘　　要：花椒(Zanthoxylum bungeanum)表型性状是区分不同地理种源大红袍花椒品种的重要依据。对17份不同地理种源的大红袍花椒叶片、果实、皮刺等15个性状进行相似性分析、主成分分析和聚类分析。结果表明:17个不同地区大红袍除了小叶数之外,其余表型性状均有不同程度的变异;聚类结果显示17个大红袍花椒分为6类,表明不同种源大红袍花椒组群间表型变异明显,不同产地花椒有明显的由西到东逐渐变化的地域性特征,但也存在交叉聚类现象。Phenotypic characters of Chinese prickly ash(Zanthoxylum bungeanum)are the important basis for distinguishing the varieties with different provenances.15 phenotypic characters like leaf,fruit and prickle characteristics,etc.from 17 provenances were conducted with similarity analysis,principal component analysis and cluster analysis.The result showed that 17 provenances performed variations in all phenotypic characters except leaf.Cluster analysis demonstrated that 17 provenances from different habitats were divided into 6 groups,indicating that there was an obvious phenotypic variation between different groups.Cluster analysis also revealed that Chinese prickly ash from different habitats had obvious regional characteristics with gradual change from west to east,but there was also cross-clustering phenomenon.
