摘要
利用最小平行进化法对蒙古高原野豌豆属植物进行了分支分类研究 ,并探讨了该属植物 5个组的演化关系 ,其进化顺序为 : Sect.Cracca → Sect.Ervum→ Sect.Vicia→ Sect.Oroboidea→ Sect.Faba该属的进化趋势为 :卷须退化 ,总状花序轴缩短 ,小叶对数减少 ,总状花序少花 ,花小 ,荚果肥厚等特点 .本文编制了蒙古高原野豌豆属植物的分亚属、分组和分种检索表 .
The minimal parallel evolutionary method of cladistic toxonomy is used in study of the genus Vicia L. in Mongolian Plateau, and discussing the evolution of the five Sect.of the genus, the sequence of its evolution as following: Sect.Cracca→Sect.Ervum→Sect.Vicia →Sect.Oroboidea→Sect.Faba The retrogression of tendril, short axis of raceme, decrease of leaves, several flowers of raceme, small flowers, fleshy legume etc. are its evolutionary direction. Compiling the key of subgenus, sect. and species in this paper.
