| 摘 要： | 采用普通压片法，以仙客来叶芽为试材对3个国内常见品种（系）的核型进行了研究，结果表明3种仙客来染色体均为二倍体，染色体数目为2n=84，核型可分为3种类型：2n=2x=84=84m、2n=2x=84=47m+30sm+7M和2n=2x=84=83m+1M；未观察到次缢痕或随体；3种仙客来染色体均属小染色体，法国彩云系列和浙江森禾国旗红系列为1B型，核型相似；比利时镭射系列为1A型。 |

| Abstract: | For the purpose of researching the classification of Cyclamen persicum Mill.On cell level.The karyptype and chromosome number of three Cyclamen persicum Mill.was studied by the method of squash with the young leaves.The results showed that all the chromosomes were diploid;the karyotypes were divided into three types,i.e.2n=2x=84=84m type,2n=2x=84=47m+30sm+7M type and 2n=2x=84=83m+1M type.There was no satellites found in the morphological observation of chromosomes;all the three types were small in size;the ... |
