东北蒿属艾组12种植物核型研究

报道东北蒿属艾组12种植物的染色体数及核型资料，结果如下：宽叶山蒿（Artemisia stolonifera (Maixm.)Komar.)2n=4x=36=28m 4sm(4SAT) 4st(4SAT);野艾蒿（A.lavandulaefolia DC)2n=2x=50=40m 4sm 6st(6SAT); 矮蒿（A.lancea Van.)2n=2x=16=10m 4sm 2st;蒙古蒿（A.mongolica (fisch.ex Bess.)Nakai]2n=2x=16=14m 2st;红足蒿（A.rubripes Nakai)2n=2x=16=14m 2st;歧茎蒿（A.igniaria Maixm.)2n=2x=34=28m 2sm 4st(4SAT);柳叶蒿（A.integrifolia Linn.)2n=4x=36=20m 12sm 4st;线叶蒿（A.subula 4st(4SAT);柳叶蒿（A.integrifolia Linn.)2n＝4x=36=20m 12sm 4st;线叶蒿（A.subulata Nakai)2n=2x=16=14m 2st;高岭蒿（A.brachyphylla Kitam.)2n=2x=18=14m 2sm 2st；林文稿A.uiridissima(Komar.)Pamp.]2n=2x=18=14m 4sm;奄癌（A.keiskeana Miq.)2n=2x=18=16m 2sm；阴地蒿（A.sylvatica Maxim.)2n=2x=16=14m 2sm，核型对称性野艾蒿（A.lavandulaefolia)为2B型，其余均为2A型，依据核型资料对个别种的演化 分类进行了初步探讨。

STUDY ON KARYOTYPES OF ARTEMISIA SECT.ARTEMISIA Y.R.LING. IN NORTHEAST CHINA

The chromosome numbers of twelve species and karyotypes of everyone of Artemisia in northeast China are reported.These included first counts for five species.The karyotype formulated are as follows: A.stolonifera 2n=4x=36=28m+4sm(4SAT)+4st(4SAT); A.lavandulaefolia 2n=2x=50=40m+4sm+6st(6SAT); A.lancea Van. 2n=2x=16=10m+4sm+2st; A.mongolica (Fisch.ex Bess.)Nakai 2n=2x=16=14m+2st; A.rubripes Nakai.2n=2x=16=14m+2st; A.igniaria Maixm. 2n=2x=34=28m+2sm+4st(4SAT); A.integrifolia Linn. 2n=4x=36=20m+12sm+4st; A.subulata Nakai.2n=2x=16 =14m+2st; A.brachyphylla Kitam.2n=2x=18=14m+2sm+2st; A.viridissima ( Komar.)Pamp. 2n=2x=18=14m+4sm; A.keiskeana Miq.2n=2x=18=16m+2sm; A.sylvatica Maxim.2n=2x=16=14m+2sm,karyotypes of these species are symmetric and belong to 2B except A.lavandulaefolia .According to the information of karyotypes ,classification and evolution of the several species were investigated.
