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。
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.
