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。
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.
