摘要
本文首次全面地报道了东北地区野豌豆属植物染色体数目。结果如下:Vicia cracca group.2n=12;V.amurensis Oett.2n=12;V.amoena Fisch.ex DC.2n=24;V.amoena var.oblongifolia Reqel 2n=12;V.amoena var.sericea Kitag.2n=12;V.geminiflora Trautv.2n=14;V.japonica A.Gray 2n=24;V.pseudorobus Fisch.et C.A.Mey 2n=12;V.multicaulis Ledeb.2n=12;V.venosa(Willd.)Maxim.2n=12;V.ramuliflora(Maxim.)Ohwi 2n=12,24;V.unij-uga A.Br.2n=12,24.结果表明该地区野豌豆种类以x=6为主,并以该基数形成较高频率的多倍体类群。根据染色体资料,对于长期存在争议的种下处理或近缘种类的划分,作者提出了新的见解。
