摘要:
本文对产于湖南的6种毛莨科植物的染色体进行了研究。裂叶星果草[Asteropyrumcavaleriei(Levl.etVant)Drumm.etHutch.)的染色体属于R型,核型公式为2n=16=12m+2sm+2t,核型类型属于ZB;打破碗花花(AnemonehupehnsisLem.)的核型公式为2n=16=10m+4st+2t(2sat),核型类型属于2A;粗齿铁线莲[Clematisapiifoliavar.argentilucida(Levl.etVant)W.T.Wang]的核型公式为2n=16=10m+2st+4t(2sat)或2n=16=10m+2st+4t(4sat)随体染色体数目在居群之间有变化,核型类型属于2A;扬子铁线莲[Clematisganipiniana(Levl.etVant)Tamura]的核型公式为2n=16=10m+2st+4t(4sat),核型类型属于2B;毛莨(RanunculuscantoniensisDC.)的核型公式为2n=16=6m+4st+6st(2sat),核型类型属于3A;毛莨(RanunculusjaponicusThunb.)的核型公式为2n=?
