对东北地区野豌豆属植物花生物学研究表明文中类群均为自花授粉植物，ＡＴＰ酶活性与柱头间的可授性有关。花粉—胚珠比高于Ｃｒｕｄｅｎ标准，开花物候期分化成早春—春季和夏季两种开花类型，表现出在物种形成时地理条件的差异。 Studies on the flower biology of Vicia from northeastern China show that the taxa belong to self-pollinating plants, and the ATPase activity is related to the stigma receptivity. The pollen-ovule ratio was higher than that of the Cruden standard. The flowering phenophase differentiated into two flowering types, early spring, spring and summer, showing the differences in the geographical conditions during species formation.
