| 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. |
