摘要: 对吊兰体细胞染色体计数,并进行核型分析。结果表明,吊兰染色体数目为2n=28;核型公式为2n=2x=28=4m+14sm+10st;染色体相对长度组成为2n=28=4L+14M2+10M1,属于3B型;全组染色体总长73.84μm,长臂总长为53.59μm;核型不对称系数为72.58%;染色体总体积为101.94μm3。

Abstract: The karyotype and the number of Chlorophytum comosum chromosome were studied. The results showed that the number of chromosome of Chlorophytum comosum is 2n=2x=28=4m+14sm+10st; the relative length of chromosome is 2n=28=4L+14M2+10M1. The total length of chromosome groups is 73.84μm, the total length of long arms is 53.59μm, and the AS.K% is 72.58%. The karyotype of Chlorophytum comosum chromosome belongs to ‘3B’ type. The total volume of chromosome is 101.94μm3.
Key words: Chlorophytum comosum, chromosome, analysis of karyotype, chromosome volume
