摘　　要：用数量分类学的方法对14种松材线虫组线虫形态进行了聚类分析。结果表明,拟松材线虫、大尖尾伞滑刃线虫、伪伞滑刃线虫、锥尾伞滑刃线虫、豆伞滑刃线虫和吉拉尼伞滑刃线虫在所选取的形态特征上表现出一致性;新加坡伞滑刃线虫、韩国伞滑刃线虫、杨伞滑刃线虫也表现出较高的一致性;拟灰黄锦天牛伞滑刃线虫、日本冷杉伞滑刃线虫、鲍嘉伞滑刃线虫和灰黄锦天牛伞滑刃线虫在形态上较为相近;松材线虫相对独立为一支。Based on method of numerical taxonomy,the clustering analysis of 14 species of xylophilus group was performed. The results showed that Bursaphelenchus mucronatus,B. macromucronatus,B. fraudulentus,B. conicaudatus,B. doui and B. gillanii showed high consistency; B. singaporensis,B. koreanus and B. populi showed high similarity; B. paraluxuriosae,B. formae,B. baujardi and B. luxuriosae were closed to each other on the dendrogram;While B. xylophilus were independent relatively on the dendrogram after hierarchical cluster analysis.
