摘要
报道了采自青海南部7 种翠雀属( Delphinium L.) 植物的染色体数目和核型。大通翠雀花D.pylzowii 的核型公式为2n= 16 = 2m + 4sm + 10st; 毛翠雀花D. trichophorum 的核型公式为2n= 16 = 2m + 4sm + 10st; 蓝白翠雀花D.albocoerulum 的核型公式为2n = 16 = 2m + 4sm(2SAT) + 10st; 囊谦翠雀花D. nangchienense 的核型公式为2n = 16 = 2m + 6sm + 8st; 唐古拉翠雀花 D.tangkulaense 的核型公式为2n = 16 = 2m (2SAT) + 6sm + 8st; 单花翠雀花 D.candelabrum var. monanthum 的核型公式为2n = 16 = 2m + 6sm + 8st; 展毛翠雀花D. kamaoensevar. glabrescens 的核型公式为2n = 16 = 2m + 6sm + 8st; 前5 种植物的染色体数目与核型为首次报道。
The chromosome numbers and karyotypes of 7 taxa of Delphinium from southern Qinghai in China in the present paper, are reported. Their karyotype formulae are D. pylzowii,2n=16=2m+4sm+10st; D. trichophorum, 2n=16=2m+4sm+10st; D. albocoerulum, 2n=16=2m+4sm(2SAT)+10st; D.nangchienense, 2n=16=2m+6sm+8st; D.tangkulaense, 2n=16=2m(2SAT)+6sm+8st; D. candelabrum var. monanthum, 2n=16=2m+6sm+8st; and D. kamaoense var.glabrescens, 2n=16=2m+6sm+8st. The chromosome numbers and karyotypes of the former five species are reported here for the first time.
