( 2n) =4x =36 =30m +4sm +2st ;光沙蒿 (A .oxycephalaKitag .var .oxycephala) ( 2n) =4x =36 =2 8m +6sm +2st;兴凯光沙蒿 (A .oxycephalaKitag .var .xingkaiensisG .Y .Zhang ) ( 2n) =4x =36=2 8m +6sm +2st;山海光沙蒿 (A .oxycephalaKitag .var .shanhaiensisG .Y .Zhang) ( 2n) =4x =36 =2M +2 8m +4sm +2st;太阳光沙蒿 (A .oxycephalaKitag .var .taiyangensisG .Y .Zhang) ( 2n) =4x =36 =2 8m +6sm +2st;柔毛蒿 (A .pubescensLedeb .var .pubescens) ( 2n) =4x =36 =2 8m +6sm +2st ;大头柔毛蒿 (A .pubescensLedeb .var .gebleriana (Bess .)Y .R .Lin ) ( 2n) =4x =36=2 8m +6sm +2st;塔河柔毛蒿 (A .pubescensLedeb .var .taheensisG .Y .Zhang) ( 2n) =4x =36 =2 8m+6sm +2st;核型类型均为 2A型。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.
