| 摘 要： | 本文首次报导了我国川产五味子五个种、变种的核型研究结果,即翅枝五味子Schisandra henryi、红花五味子S.rubriflora、华中五味子S.sphenanthera、柔毛五味子S.pubescens、毛脉五味子S.pbueecens var.pubineryis。它们的染色体都是28条,核型比较对称。翅枝五味子、柔毛五味子和毛脉五味子的核型公式为:2n=28=24m+4sm,红花五味子的核型公式为:2n=28=22m+6sm,华中五味子的核型公式为:2n=28=26m+2sm。

| Abstract: | The present paper reports karyotypes in 4 species and 1 variety of Schisandra Michx. in Sichuan, PRC. It is found that the numbers of the species and variety are diploid, with 2n=28; their complements are made of m and sm chromosomes. All of these karyotypes are symmetrical and primitive. It can be simplied as follows: S.sphenanthera 2n=2x=28=26m+2sm; S.rubriflora 2n=2x=28=22m+6sm; S.henryi, S.pubescens, S.pubescens var. pubinervis 2n=2x=28=24m+4sm. |
