对紫葳科角蒿属(Incarvillea)6种植物(其中两头毛Incarvillea arguta包括红花和白花2个类型)进行了核形态学研究.它们的间期核均为简单染色中心型,前期染色体为中间型,体细胞中期染色体数目均为2n=22,核型公式分别为:(1)两头毛(红花类型)Incarvillea ar-guta(Red-flower form)2n=22=14m+(2SAT)+8sm(1SAT),着丝点端化值(T.C.%)为62.71%,臂指数(N.F.值)为44;(la)两头毛(白花类型)I.arguta(White-flower form)2n=22=16sm(1SAT)+6st,T.C.%值为70.62%,N.F.值为38;(2)鸡肉参I.mairei 2n=22=6n+8sm(1SAT)+8st,T.C.%值为70.07%,N.F.值为36;(3)红波罗花I.delavayi 2n=22=10m+6sm+6st,T.C.%值为61.33%,N.F.值为38;(4)单叶波罗花I.forrestii 2n=22=4m+8sm+10st(1SAT),T.C.%值为73.10%,N.F.值为34;(5)中甸角蒿I.zhongdianensis 2n=22=4m+8sm+10st,T.C.%值为72.31%,N.F.值为34;(6)黄波罗花I.lutea 2n=22=4m+8sm(2SAT)+10st,T.C.%值为69.47%,N.F.值为34.上述几种植物中,除两头毛(红花类型)的核型不对称性为2A型外,其余几种的核型不对称性都属于3A型.本文观察的6种植物的核形态结构均为首次报道.
