| 摘 要： | 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 + 4 sm (1SAT) + 1 st (1SAT) + 2 t; 新疆杨( P. alba var. py ram idalis) , 2n = 38 = 1M + 24m + 6 sm + 5 st (1SAT) + 2 t (1SAT) ; 河北杨( P. hopeiensis Hu et Chow) , 2n = 38 = 1M + 25m + 8 sm + 4 st; 毛白杨( P. tomentosa Carr) , 2n = 38 = 1M + 27m + 2 sm + 6 st + 2 st; 欧洲山杨( P. trem ula L. ) ,2n = 38 = 27m (1SAT) + 6 sm + 5 st (2SAT) ; 银新杨( P. alba bolleana) , 2n = 38 = 1M + 24m + 7 sm (1SAT)+ 5 st (1SAT) + 1 t; 鄂西毛白杨(P. tom entosa var. Exi) , 2n = 38 = 26m + 5 sm + 4 st + 3 t; 喇叭1号( P. davidiana Dode CL alba21) , 2n = 38 = 3M + 23m ( 1SAT) + 6 sm + 6 st ( 1SAT) , B14 杨( P1 ×Zhongbainensis B14) , 2n = 38 = 22m + 6 sm (1SAT) + 7 st + 3 t。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。 |

| Abstract: | The karyotype of 9 species ( varieties) of section Populus in the genus Popu lus have been analyzed for the first time. The resultswere as follows: P. alba L. , 2n = 28 = 1M + 30m + 4 sm (1SAT) + 1 st (1SAT) + 2 t; P. alba L. var. pyram idalis, 2n = 38 = 1M + 24m + 6 sm + 5 st (1SAT) + 2 t (1SAT) ; P. hopeiensis Hu et Chow, 2n = 38 = 1M + 25m + 8 sm + 4 st; P. tom entosa Carr. , 2n = 38 = 1M + 27m + 2 sm + 6 st + 2 st; P. trem ula L. , 2n = 38 = 27m (1SAT) + 6 sm + 5 st (2SAT) ; P. a lba bolleana, 2n = 38 = 1M + 24m + 7 sm (1SAT) + 5 st (1SAT) + 1 t; P. tom en tosa var. Ex i, 2n = 38 = 26m + 5 sm + 4 st + 3 t; P. davidianaDode CL alba21, 2n = 38 = 3M + 23m (1SAT) + 6 sm + 6 st (1SAT) ; P1 ×hongba inensis B14, 2n = 38 = 22m + 6 sm (1SAT) + 7 st + 3 t. Results of karyotype analysis showed that the karyotype differences among species ( varieties) in section Populus were remarkable. The results obtained indicated that their origin were different. The karyotype characteristics provided important basic data for species of section Populus. |
