| 摘 要： | 本文报道了国产北野豌豆Vicia ramuliflra(Maxim.)Ohwi和日本产V.fauviei Franch.和V.nipponica Matsum.的核型。北野豌豆古莲居群2n=12=2m(2SAT)+8sm+2st, 千山居群2n=12=6m+6sm。V.fauriei 2n=12=2m+8sm+2st, V.nipponica 2n=12=6m(4SAT)+4sm+2st, 核型分析表明核型主要由'm'、'sm'和'st'三种染色体组成, 核型对称性高(2A或3A)。染色体倍性分布格局, 形态特征和现代分布式样揭示黄山-西天目山-庐山-带山地可能是柳叶野豌豆复合种及其近缘种的起源中心和多样化中心, 四倍体的发生可能与第四纪山地冰川有关。 |
| 关 键 词： | 柳叶野豌豆复合种 牯岭野豌豆 野豌豆属 核型 细胞地理学 |

| Abstract: | Karyotypes of V. vencsa complex (V. venosa-V. ramuliflora) and its al-lied species were studied here. Karyotype formulas of those taxa areshowed as follow: V. ramuliflora 2n = 12 = 2m (2SAT) + 8sm + 2st and 2n = 12 =6m + 6sm; V. nipponica 2n = 12 = 6m (2SAT) + 4sm (2SAT) + 2st; V. fauliei 2n =12 = 2m + 8sm + 2st. The region of Mt. Huangshan-Mt. Lushan-Mt. Xitian-mushan may be centres of origin and diversity based on distribution patt-ern of chromosome ploidy, morphological features (especially flower) andpattern of modern distribution. |
