摘　　要：采用压片法,对生长在武汉地区的药用植物茴香(Foeniculum vulgareMiller)进行细胞学研究。结果表明:茴香的绝大多数花粉母细胞减数分裂过程中染色体的行为正常,终变期形成11个二价体,为染色体计数的最佳时期;茴香的染色体数目为2n=2x=22,核型公式为K(2n)=22=20m+2sm,其染色体相对长度组成为2n=2s+8M1+10M2+2L,属于“1A”对称型核型。Cytologic study on F. vulgare Miller, a medical plant cultivated in Wuhan, was conducted through the squash method. The result showed that chromosomes of most pollen mother cells behaved normaly during the meiotic divisions . There are 11 bivalents formed at diakinesis which is the optimal time for chromosome count. The chromosome number was found to be 2n= 2x= 22, karyotype formula： K（2n） = 22= 20m＋ 2sm, constitution of relative length： 2n= 2s＋ 8M1＋10M2＋2L and karyotype type is symmetrical, belong to 1A.
