东北蒿属莳萝蒿组6种植物核型研究

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

    摘要
  • 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(Artemisia sieversiana Ehrhart ex Willd)2n=2x=18=14m＋2sm(2SAT)＋2st(SAT);矮滨蒿(A. nabai Pamp)2n=2x=16=12m+4sm;碱蒿(A. anethifoloa Web. ex Stechm.)2n=2x=16=12m+2sm+4smt;莳萝蒿(A. anethoides Mattf)2n=2x=16=12m＋4sm(2SAT);肇东蒿(A. zhaodongensis G. Y. Zhang.)2n=2x=16=12m(2SAT)＋4sm(2SAT);核型对称性均为2A型。冷蒿(A. frigida Willd)2n=90。

     

    Abstract: 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.
