摘要
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。
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： ①Looicera 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; ② The 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. lsika, but it had not close relationships with the Subsect of Sect. Isika;④There is a close relationships between L. caerulea vat. edulis and other species of Subsect. so it did not support the L. caerulea var. edulis as a new genus.
