摘要
对桔梗体细胞染色体计数,并进行核型分析.结果表明:桔梗染色体的数目为2n=18,核型公式K(2n)=2X=6 m(2SAT)+12 sm,核型类型属于2A型,较不对称,为较原始类型.
The chromosome number of Playtcodon grandiflourus were numbered and its karyotype was analysed. The results showed that its chromosome number was 2n = 18, and the karyogram formula was K（2n） = 2X = 6 m（2SAT） ＋ 12 sin. The karyogram was belonged to the type of 2A, and it was asymmetric and relatively primitive.
