Giemsa C-banding Analysis in Eight Species of Genus Epimedium(Berberidaceae)

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.
