| 摘 要： | 为加快对锦鸡儿植物的开发和利用,利用细胞学研究方法,首次对中间锦鸡儿进行染色体核型分析。结果表明:中间锦鸡儿(C.intermedia Kuang et H.C.Fu)染色体数为2n=18,其核型公式为2n=2x=18=16 m(4SAT)+2M;按stebbins的核型分析原则,中间锦鸡儿的核型属1A型。此外,有关核型的变异范围也进行了讨论。

| Abstract: | The karyotype of C.intermedia Kuang et H.C.Fu was studied wth cell technology.We found that the Chromosome number of the somatic cells was 2n=18,the karyotype formula was 2n=2x=18=16m(4SAT) 2M.The result of chromosome examination showed that it belonged to "1A" type of Stebinns karyotypic asymmetry.which meant it was a primitive species.In addition the extent of Karyotype variation was curt dicussed. |
