摘要: 对我国辽宁地区毛莨科(Ranunculaceae)乌头属(Aconitum) 6个种的染色体的数目和形态进行了研究,并进行了核型分析。其染色体基数为X=8,核型公式为:两色乌头:2n=2x=2m+10sm+4st;蛇岛乌头为:2n=4x=10m+20sm(SAT)+2st+2B;黄花乌头为:2n=4x=4m+12sm(SAT)+8st+1B;北乌头三倍体为:2n=3x=2M+4m+18sm;北乌头4倍体为2n=4x=4m+28sm。同时,对乌头属下某些种的分类学问题进行了探讨。

Abstract: This paper reports chromosome number and chromosome morphology of 6 species of Aconitum in Liaoning area.The basic chromosome number of Aoconitum in Liaoning area could be X=8.The karyotype are: K(2n=16)=2m+10sm+4st for A.alboviolaceum; K(2n=32+2B)=10m+20sm(SAT)+2st+2B for A.fauriei; K(2n=24+1B)=4m+12sm(SAT)+8st+1B for A.coreanum; K(2n=32+1B)=18m+18sm+6st+1B and K(2n=24)=2M+4m+18sm for A.kusnezoffii; K(2n=32)=6m+16sm+8st+2t for A.jaluense; K(2n=32)=14m+18sm for A.liaotungense.Meantime, some disscusion are given on the problems in Aconitum.

Key words: Aconitum, Karyotype, Chromosome.
