摘要
报道东北蒿属莳萝蒿组6种植物的染色体数,5种为首次报道,对其中的5种进行了核型分析。核型公式分别为:大籽蒿(ArtemisiasieversianaEhrhartexWilld)2n=2x=18=14m+2sm(2SAT)+2st(SAT);矮滨蒿(A.nabaiPamp)2n=2x=16=12m+4sm;碱蒿(A.anethifoloaWeb,exStechm.)2n=2x=16=12m+2sm+4smt;莳萝蒿(A.anethoidesMattf)2n=2x=16=12m+4sm(2SAT);肇东蒿(AzhaodongensisG.Y.Zhang.)2n=2x=16=12m(2SAT)+4sm(2SAT);核型对称性均为2A型。冷蒿(A.frigidaWilld)2n=90。
The Chromosome numbers of six species and karyotypes of five ones ofArtemisia 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 frigida2n = 90.
