摘要
通过对东北地区应用的丁香属植物的形态学性状的观察,采用分支系统学的方法对其进行分支分析,利用PHYLIP和MEGA软件,分别应用最大简约法和UPGMA法对其进行系统发育分析,结果表明:经UPGMA聚类分析并不支持传统的分类方法(即将丁香属内划分两个组,即长花冠管组(Sect.Syringa)和短花冠管组(Sect.Ligustrina)),而认为,短花冠管组在分子系统树中位于长花冠管组内部,因此认为去除组的划分,将丁香属分为五系,即顶生花序系(Ser.Villosae)、欧丁香系(Ser.Syringa)、巧玲花系(Ser.Pubescentes)、羽叶丁香系(Ser.Pinnatifoliae)和短花冠系(Ser.Ligustrina)。
In this paper a cladistic analysis of the genus out through surveying on the morphologic characters and PHYLIP. The results showed that 11 species of Syringa Syringa from, the Northeastern China was carried using MP and UPGMA methods by MEGA and were divided into four clades and belonged to relevant Series of Sect Ⅰ. Ligustrina and Sect Ⅱ. Syringga classified. So it is well supprted to Eehder＇ s infrageneric system. Through analysis we considered that the genus Syringa would be divided into five series, Ser. Villosae, Ser. Syinga, Ser. Pubescenter, Ser. Pinnatifoliae and Ser. Ligustrina.
