摘 要：
以保定野菊(Chrysanthemum indicum)、菊花脑(C.nankingense)、元氏甘菊(C.lavandulifolium)、龙脑菊(C.japonicum)、若狭滨菊(C.japonicumvar.wakasaense)、淄博野菊(C.indi-cum)6种菊属植物为试材进行细胞学研究。结果表明:保定野菊的核型公式为2n=2x=18=16m+2st,核不对称系数为56.58%;菊花脑的核型公式为2n=2x=18=12m+6sm,核不对称系数为60.47%;元氏甘菊的核型公式为2n=2x=18=12m+4sm+2st,核不对称系数为62.12%;龙脑菊的核型公式为2n=2x=18=14m+4sm,核不对称系数为66.46%;若狭滨菊的核型公式为2n=4x=36=28m+6sm+2st,核不对称系数为59.92%。淄博野菊的核型公式为2n=4x=36=26m+10sm,核不对称系数为65.88%。

摘 要：
Taking six species Chrysanthemum of Chrysanthemum indicum of Baoding,Chrysanthemum nankingensem,Chrysanthemum lavandulifolium,Chrysanthemum japonicum,Chrysanthemum japonicum var.wakasaense,Chrysanthemum indicum of Zibo as test material,the its cytology were studied.The results showed that their karyotype formula and index of karyotypic asymmetry(As.k),C.indicum:2n=2x=18=16m+2st,As.k=56.58%.C.nankingense:2n=2x=18=12m+6sm,As.k=60.47%.C.lavandulifolium:2n=2x=18=12m+4sm+2st,As.k=62.12%.C.japonicum:2n=2x=18=14m+4sm,As.k=66.46%.C.japonicum var.wakasaense:2n=4x=36=28m+6sm+2st,As.k=59.92%.C.indicum:2n=4x=36=26m+10sm,As.k=65.88%.
