摘　　要：对在我省分布较为广泛的红花五味子S.rubrifolia ,翅枝五味子S .henryi,华中五味子S.sphenanthera ,柔毛五味子S .pubescens,毛脉五味子S .pubescensVar.pubinervis的核型进行了研究。研究结果表明 ,染色体数均为 2 8,核型不对称系数 5 8.90 % ,核型分类属于 1A到 2B ,表明其染色体比较对称 。The kyryotypes of Schisandra rubrifolia, S. henryi, S. sphenanthera, S. pubescens and S. pubescens var. pubinervis were studied. The results showed that their chromosome number is 28, the coefficient of asymmetry is 58.90% and their karyotypes are 1A to 2B by classification, suggesting that they are relatively primitive forms.
