The results show that the numbers of the somatic chromosome are 2n=16,and the karyotype formulae are as follows:Caragana intermedia Kuang et H.C. Fu 2n=2x=16=10m+6sm; C.

• 结果表明,3种锦鸡儿的体细胞染色体数目2n=16,核型公式分别为:中间锦鸡儿2n=2x=16=10m+6sm、柠条锦鸡儿2n=2x=16=12m+4sm、狭叶锦鸡儿2n=2x=16=14m+2sm,中间锦鸡儿和柠条锦鸡儿的核型属于2A型,狭叶锦鸡儿的核型属于2B型。
