摘要
本文报道了国产6种柴胡的核型,发现在肇东五里木存在一种与日本产三岛柴胡B.falcatum具有相同核型特征的柴胡,暂称其五里木居群。柞柴胡B.komarovianumLincz.2n=8=2m+6sm(2SAT).红柴胡Bscorzonerifoliu,Willd.2n=12=10m(2SAT)+2sm.北柴胡BchinenseDC.2n=24=14m+10sm(2SAT).锥叶柴胡B.bicauleHelm2n=32=20m+12sm.大叶柴胡B.longiradiatumTurcz.2n=12=10m(2SAT)+2sm五里木居群2n=26=16m+10sm(2SAT)文章最后根据核型特征分析了东北地区各种柴胡间的演化关系.
This paper reported karyotypes of six taxa of Bupleurum L. and discovered that new taxon in Wulimu, Zhao dong county had the same karyotype as B. falcatum in Japan,which was called temporarily to Wulimu population. Karyotype formulas of those taxa are showed as follows: B. komarovianum Lincz. 2n= 8 = 2m+6sm(2SAT). B. scorzonerifolium Willd. 2n= 12= 20m+12. B. chinense DC. 2n =24= 14m+10sm(2SAT). B. bicaule Helm 2n = 32== 10m(2SAT)+2sm. B. longiradiatum Turcz. 2n =12 = 10m(2SAT)+2sm. Wulimu population 2n = 26= 16m+10sm (2SAT). It was discussed that evolutionary relationchips among those taxa of Bupleurum L. in Northeast China based on karyotypic characters.
