摘要
报道了芝麻菜(Eruea Sative Mill.)及其变种绵果芝麻菜(E.Sativa var.eriocarpa Boiss.)的核型研究结果。二者根尖分生细胞的二倍染色体数均为2n=22,花粉母细胞的单倍染色体数均为n=11,核型公式芝麻菜为2n=22=16m(2SAT)+6sm(2SAT),绵果芝麻菜为2n=22=18m(2SAT)+4sm(2SAT).
The karyotype of Eruca sativa and E. sativa var. eriocarpa was studied. Their chromosome number is 2n=22, n=11.The karyotype formula of E. sativa is 2n=22=16m(2SAT)+65m (2SAT), while that of E. sativa var. eriocarpa is 2n=22=18m(2SAT)+4sm (2SAT). The data of the karyotype analysis of E. sativa and E. sativs var. eriocarpa were reported for the first time in this paper.
