摘要:
本文首次报道黄精属PolygonatumMill我国三种特有植物的染色体数目和核型,结果如下:安徽黄精P.anhuiense发现两个细胞型:(1)2n=24=4m+6sm+14st;(2)2n=20=4m十6sm+10st;  黄精P.langyaensy2n=18=6m+8sm+4t;距药黄精P.franchetii有三个细胞型:(1)2n=22=8m+8sm(2sc)+6st;(2)2n=20=2m+14sm+4st;(3)2n=18=4m+8sm+4st+2T,全部属3B核型。黄精属植物安徽共有10种,本文对9种黄精的染色体数目、核型进行了比较研究,发现它们可划分成三个类群,与中国植物志(第十五卷)的形态分类基本相符。
