对杨属(Populus)白杨组(Section Populus)9种核型进行了分析,结果如下:银白杨(P.alba L.),2n=28=1M+30m+4sm(1SAT) +1st(1SAT) +2t;新疆杨(P. alba var. pyramidalis),2n=38=1M+24m+6sm+5st(1SAT) +2t(1SAT);河北杨(P.hopeiensis Hu et Chow),2n=38=1M+25m+8sm+4st;毛白杨(P. tomentosa Carr),2n=38=1M+27m+2 sm+6st+2st;欧洲山杨(P. tremula L.),2n=38=27m(1SAT) +6sm+5st(2SAT);银新杨(P. alba bolleana),2n=38=1M+24m+7sm(1SAT) +5st(1SAT) +1t;鄂西毛白杨(P. tomentosa var. Exi),2n=38=26m+5sm+4st+3t;喇叭1号(P. davidiana Dode CL alba-1),2n=38=3M+23m(1SAT) +6sm+6st(1SAT),B14杨(P.×Zhongbainensis B14),2n=38=22m+6sm(1SAT) +7st+3t.白杨组种间核型有显著差异,说明它们的起源各异,其核型特征为白杨组种间鉴定提供了参考依据.
