| 摘 要： | 通过对番红花根尖细胞进行染色体常规制片,并进行核型分析.结果显示,番红花为2倍体(2n=2x=24)植物,核型公式为K(2n)=2x=24=2t+2st+8sm+12m,其中,中部着丝粒染色体(m)6对,近中部着丝粒染色体(sm)4对,近端着丝粒染色体(st)1对,端着丝粒染色体(t)1对.核型类型为2B,并且倍性不是...

| Abstract: | The karyotype of Crocus sativus was analyzed by the chromosomal preparation of its root tip cell.The results showed that the chromosome number was 2n=24 and its karyotype formula was K(2n)=2x=24=2t+2st+8sm+12m.There were six pairs of metacentric chromosome,four pairs of sub-metacentric chromosome,one pair of acrocentric chromosome and one pair of telocentric chromosome.The karyotype of Crocus sativus belonged to 2B of Stebbins.The ploidy of saffron was not the reason of the sterility. |
