摘要
以"云麻1号"的大麻芽株为试材,对大麻体细胞染色体的数目及其核型进行了研究,结果表明:大麻体细胞染色体的数目为2n=20,染色体核型公式为2n=20=2x=14 m+6 sm,属于2A型染色体,其N.F值为40,着丝点端化值(T.C.%)为56.35%。
Taking the germinating plant of cultivar ＂Yunma 1 ＂ of Cannabis sativa as experiment materials, the chromosome number and karyotype analysis of somatic cells were analyzed. The results are as follows： the chromosome number of somatic cell is 2n = 20, the karyotype formula is 2n = 20 = 2x = 14m ＋ 6sm, which belongs to 2A type, theN. F is 40, T.C. % is 56.35 %.
