摘要:

对中国特有植物膀胱豆(Colutea delavayi)及两个邻近种鱼鳔槐(C.arborescens)和东方鱼鳔槐(C.orientalis)进行了核形态学研究。膀胱豆核型公式为:2n=2x=16=16m;东方鱼鳔槐核型公式为:2n=2x=16=12m+4sm;鱼鳔槐核型公式为:2n=2x=16=10m+6sm,染色体数2n=16与前人报道一致。三种植物中,除了鱼鳔槐的核型不对称性为2A型外,另两种的核型不对称性均属于1A型。

关键词: 鱼鳔槐属, 膀胱豆, 核型, 染色体数目

Abstract:

 Chromosome numbers and karyotypes of three species from Colutea (Leguminosae), C.delavayi, C.orientalis and C.arborescens were studied, of which C.delavayi is an endemic to SW China. C.arborescens 2n=2x=16=10m+6sm with type 2A asymmetry and C.orientalis 2n=2x=16=12m+4sm with type 1A asymmetry, the basic chromosome number 2n=16 is also confirmed. C.delavayi 2n=2x=16=16m with type 1A asymmetry was reported firstly.

Key words: Colutea, Colutea delavayi, Karyotype, Chromosome number
