摘要: 应用BSG方法对淫羊藿属(Epimedium)8个种的Giemsa C带进行了比较研究。结果表明,有15~22条C带,包含着丝粒带、端带、中间带、中间随体带等类型;根据带纹数目和位置,8个种可分为三类:Ⅰ类是E.sagittatum,显示的C带最少,仅有15条;Ⅱ类是原产德国的E.alpinum和E.pubigerum,显示的C带较少,均为18条;Ⅲ类是其余的5种,即:E.acuminatum、E.simplicifluom、E.wushanense、E.leptorrhizum、E.davidi,这类植物显示的C带数目较多,不少于20条。

Abstract: The C-banding patterns in 8 species of genus Epimedium(Berberidaceae) were studied and compared by a modified BSG technique.Results showed that the C-banding patterns of 8 species studied in this paper were different,respectively with 15 to 22 bands,consisting of centromeric bands,intercalary bands,terminal bands and the middle satellite C-bands.Based on the number and location of the bands,the tested 8 species can be divided into three groups:Group Ⅰ comprises E.sagittatum,with only 15 C-bands;Group Ⅱ,E.alpinum and E.puberginum native to Germany,with 18 C-bands;Group Ⅲ,E.acuminatum,E.simplicifluom,E.wushanense,E.leptorrhizum and E.davidi,with the C-band number from 20 to 22.
