| 摘 要： | 分析九龙山野生蕉(M.balbisiana)的染色体数目、核型及核型模式图。结果表明:其核型类型为"2A"型,染色体主要由中部着丝点染色体组成,核型公式为:K(2n)=22=18m+4sm(2SAT),几乎对称,为较原始类型。并结合核型数据讨论其分类地位。

| Abstract: | The chromosome number and karyotype of Jiulongshan wild banana were analyzed.The results showed that the chromosome number was 22,and the karyotype formula was K(2n)=22=18m+4sm(2SAT),which was a 2A type by Stebbins's classification standard,and was a relatively primitive form.Meanwhile,it's taxonomic status was discussed based on karyotype data. |
