| 摘 要： | 对中国杨属Populus L. 5组14种(银白杨P. alba L.、河北杨P. hopeiensis Hu & Chow、毛白杨P. tomentosa Carr.、欧洲山杨P. tremula L.、小叶杨P. simonii Carr.、辽杨P. maximowiczii Henry、大青杨 P. ussuriensis Kom. 、青杨P. cathayana Rehd.、小青杨P. pseudo-simonii Kitag.、香杨P. koreana Rehd.、毛果杨P. trichocarpa Torr. & Grog.、大叶杨P. lasiocarpa Oliv.、欧洲黑杨P. nigra L.、胡杨P. euphratica Oliv.),3变种(新疆杨P. alba L. var. pyramidalis Bge.、箭秆杨P. nigra L. var. thevestina Bean.、钻天杨P. nigra L. var. italica (moench.) Koehne),3杂交种(小钻杨P.×xiaozhuanica W. Y. Hsu & Liang、北京杨P.×beijingensis W. Y. Hsu、加杨P.×canadensis Moench、晚花杨P.×canadensis Moench cv. “serotina” 、沙兰杨P.×canadensis Moench cv. “Sacrau 79”和意大利214杨P.×canadensis Moench cv. “I-214”)进行了染色体计数。发现白杨组的毛白杨P. tomentosa Carr. 、 黑杨组的沙兰杨P. ×canadensis Moench cv. “Sacrau 79”和意大利214杨P. × canadensis Moench cv. “I-214”为三倍体(2n=3x=57),其余均为二倍体(2n=2x=38)。

| Abstract: | Chromosome numbers and ploidy levels of 14 Chinese Populus species (Populus alba L., P. hopeiensis Hu & Chow, P. tomentosa Carr., P. tremula L., P. simonii Carr., P. maximowiczii Henry, P. ussuriensis Kom., P. cathayana Rehd., P. pseudo-simonii Kitag., P. koreana Rehd., P. trichocarpa Torr. & Grog., P. lasiocarpa Oliv., P. nigra L., P. euphratica Oliv.), three varieties (P. alba L. var. pyramidalis Bge., P. nigra L. var. thevestina Bean., P. nigra L. var. italica (moench.) Koehne) and three hybrid species (P. ×xiaozhuanica W. Y. Hsu & Liang, P. ×beijingensis W. Y. Hsu, P. ×canadensis Moench, P. ×canadensis Moench cv. “serotina”, P. ×canadensis Moench cv. “Sacrau 79”, P. ×canadensis Moench cv. “I-214”) are reported. These taxa represent five sections of the genus. P. tomentosa of section Populus and P. ×canadensis Moench cv. “Sacrau 79”, P. × canadensis Moench cv. “I-214” of section Aigeiros were triploid (2n=2x=38), while the remaining taxa were diploid (2n=2x=38). |
