15种忍冬属植物的数量分类研究

选取37个形态学性状,应用数量分类学原理与方法对15种忍冬属植物进行了研究。结果表明:忍冬属植物不是以亚属为单位分成两大类的,而是蓝果亚组(Subsect.Caerulea)形成一个类群,其它亚组形成另一个大的类群;空支组(Sect.Coeloxylosteum)的种自然聚在一支,说明传统分类的依据是正确的;蓝果亚组组内亲缘关系较近,但与囊管组(Sect.Isika)内其他各亚组之间的亲缘关系较远;蓝靛果(L.caerulea var.edulis)与蓝果亚组内其他种的亲缘关系较近,故不支持将蓝靛果分离出忍冬属另立新属。

Study on Numerical Taxonomy of 15 Species of Lonicera L.

Based on 37 morphological characters,15 species of Lonicera L.were studied by means of numerical taxonomic methods in this paper.The results were as follows:①Lonicera L.can be divided into two groups not by subgenus,but by Subsect.Subsect.Caerulea form a group,the other subsects form another large group;②The species of Sect.Coeloxylosteum naturally gathered together,which shows that the traditional classification is basically right;③Subsect.Caerulea had close relationships with other Subsects.of Sect.Isika,but it had not close relationships with the Subsect of Sect.Isika;④There is a close relationships between L.caerulea var.edulis and other species of Subsect.so it did not support the L.caerulea var.edulis as a new genus.
