摘要： 依据10个重要的外部检索性状对华东地区43份结线草属植物进行聚类分析,在欧氏距离0.93处,可将其分为五个形态类型,即结缕草、宽叶型中毕结续革、中间型中毕结缕草、长花结缕草以及细叶型结缕草。根据主成分分析结果,制订出各类型外部性状检索表。各类型评用价值排序为:细叶型结缕草>中间型中华结缕草>宽叶型中华结缕草>结缕草>长花结缕草。

关键词: 结缕草属植物, 形态类型, 坪用价值

Abstract: Morpbologicol clustering analysis is carried on 43 accessions of zoysiagrass based on10 important morphological key characters.Five types are derived.The key to these ty7e is basedon the restilt of PCA.Turfgrass quality of five types are derived.Turf grass quality of five types ofzoysiagrass is ranked as: fine type Zmpia willd.> middle type of Z.sinica Hance.> broaderleaf type of Z.sinica Hance.> Z.japonica Steud.> Z.sinica var.longfiora.
