摘要
三色堇(garden pansy)Viola tricolor var. hortensis体细胞染色体数2n=2x=26,核型公式是2n=26=14m(4SAT)+6sm+2st+4T,按Stebbins核型分类原则,三色堇核型属于2C型,在进化上属于进化程度高的类型。
The karyotype of(garden pansy)Viola tricolor var.hortensis was analyzed.The chromosome numbers of the somatic cell are 2n=2x=26.The karyotype formula is 2n=26=14m(4SAT)+6sm+2st+4T.The result of chromosome examination showed that it belongs "2C" type of Stebbins' karyotype asymmetry.That means it is a primitive species.
