STUDY ON KARYOTYPES OF ARTEMISIA SECT. ABSINTHIUM DC. IN NORTHEAST CHINA

The Chromosome numbers of six species and karyotypes of five ones of Artemisia in Northeast China are reported. These included first counts for five species.The karyotype formulae are as follows: A. sieversiana 2n= 2x= 18= 14m + 2sm (2SAT)+2st (SAT); A. nabai 2n = 2x = 16 = 12m + 4sm; A. anethitolia 2n=2x= 16= 12m +2sm + Zst; A. anethoides 2n = 2x = 16 = 12m + 4sm (2SAT) A. zhaodongensis 2n =2x=16= 12m (2SAT) + 4sm (2SAT). Karyotypes of these species belong to 2A. A. frigida 2n = 90.
