中国葡萄属植物形态学聚类分组研究

Cluster Analysis of Chinese Wild Grape Species Based on Morphological Characters

对《中国葡萄志》描述的38个中国葡萄属野生种和1个栽培种,按照《葡萄种质资源描述规范和数据标准》的要求,对18个描述符用代码数量化并进行聚类分析,根据形态特征的相似程度,将我国葡萄属野生种和欧亚种划分为8个组和5个亚组。第1组包含毛葡萄、腺枝葡萄、龙泉葡萄、美丽葡萄和庐山葡萄;第2组包含麦黄葡萄和小叶葡萄;第3组包含5个亚组21个种类,其中亚组1包含山葡萄、陕西葡萄、浙江蘡薁、蘡薁和湖北葡萄,亚组2包含绵毛葡萄和勐海葡萄,亚组3包含小果葡萄、云南葡萄和葛藟葡萄,亚组4包含毛脉葡萄、华东葡萄、武汉葡萄和井冈葡萄,亚组5包含刺葡萄、秋葡萄、桦叶葡萄、网脉葡萄、蒙自葡萄、凤庆葡萄和河口葡萄;第4组仅包含欧洲葡萄;第5组包含温州葡萄、红叶葡萄、复叶葡萄、乳源葡萄和狭叶葡萄;第6组包含东南葡萄、罗城葡萄和闽赣葡萄;第7组仅包含菱叶葡萄;第8组仅包含鸡足葡萄一个种。

Based on Descriptors and Data Standard for Grape（Vitis L.）,eighteen descriptors were selected to make cluster analysis for 38 Chinese wild grape species and Vitis vinifera from Chinese Ampelography.The results showed that 39 species had been clustered into 8 sections and 5 subsections according to the similarity o f morphology.The first section had 5 species,which included V.heyneana,V.adenoclada,V.longquanensis,V.bellula and V.hui,the second section had V.bashanica and V.sinocinerea,the third section had 21 species and consisted of 5 subsections,the first subsection contained V.amurensis,V.shenxiensis,V.zhejiang-adstricta,V.bryoniaefolia and V.silvestrii,the second subsection had V.retordiiand V.menghaiensis,the third subsection had V.balanseana,V.yunnanensis and V.flexuosa,the fourth subsection had V.piloso-nerva,V.pseudoreticulata,V.wuhanensis and V.jinggangensis,the fifth subsection contained 7 species,such as V.davidii,V.romaneti,V.betulifolia,V.wilsonae,V.mengziensis,V.fengqinensis and V.hekouensis,the fourth section had only V.vinifera,the fifth section had V.wenchouensis,V.erythrophylla,V.piasezkii,V.ruyuanensis and V.tsoii,the sixth section had V.chunganensis,V.luochengensis and V.chungii,the seventh section had only V.hancockii,the eighth section had only V.lanceolatifoliosa.
