摘要: 报道了东北蒿属龙蒿组10个分类群植物的核型。核型公式分别为:龙蒿(Artemisia dracunculus L.)(2n)=4x=36=28m+8sm;猪毛蒿(A. scoparia Waldst.et Kit.(2n)=2x=16=12m+4sm;盐蒿(A. halodendron Turcz.ex Bess.)(2n)=4x=36=30m+4sm+2st;光沙蒿(A. oxycephala Kitag. var. oxycephala)(2n)=4x=36=28m+6sm+2st;兴凯光沙蒿(A. oxycephala Kitag. var. xingkaiensis G.Y.Zhang)(2n)=4x=36=28m+6sm+2st;山海光沙蒿(A. oxycephala Kitag. var. shanhaiensis G.Y.Zhang)(2n)=4x=36=2M+28m+4sm+2st;太阳光沙蒿(A. oxycephala Kitag. var. taiyangensis G.Y.Zhang)(2n)=4x=36=28m+6sm+2st;柔毛蒿(A. pubescens Ledeb. var. pubescens)(2n)=4x=36=28m+6sm+2st;大头柔毛蒿(A. pubescens Ledeb. var. gebleriana(Bess.)Y.R.Lin)(2n)=4x=36=28m+6sm+2st;塔河柔毛蒿(A. pubescens Ledeb. var. taheensis G.Y.Zhang)(2n)=4x=36=28m+6sm+2st;核型类型均为2A型。

Abstract: The Chromosome numbers and karyotypes of ten taxon to Artemisia Sect. Dracunculus Bess. in Northeast China are reported. The karyotype formulae are as follows: Artemisia dracunculus L. (2n)=4x=36=28m+8sm; A. scoparia Waldst. et Kit. (2n)=2x=16=12m+4sm; A. halodendron Turcz. ex Bess.(2n)=4x=36=30m+4sm+2st; A. oxycephala Kitag. var. oxycephala (2n)=4x=36=28m+6sm+2st; A. oxycephala Kitag. var. xingkaiensis G. Y. Zhang (2n)=4x=36=28m+6sm+2st; A. oxycephala Kitag. var. shanhaiensis G.Y.Zhang(2n)=4x=36=2M+28m+4sm+2st; A. oxycephala Kitag. var. taiyangensis G.Y.Zhang (2n)=4x=36=28m+6sm+2st; A.pubescens Ledeb. var. pubescens (2n)=4x=36=28m+6sm+2st; A. pubescens Ledeb. var. gebleriana (Bess.) Y. R. Lin (2n)=4x=36=28m+6sm+2st; A. pubescens Ledeb. var. taheensis G.Y. Zhang (2n)=4x=36=28m+6sm+2st.
