| 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; |
