| 摘 要： | 为了丰富当地杨树种质资源，从南京林业大学引种4个美洲黑杨无性系进行扦插育苗试验，结果表明：4个无性系中，895杨、797杨、95杨在当地均有良好的生长适宜性，其苗高分别为对照加拿大杨的124．3％、116．8％和114．2％，地径分别为对照加拿大杨的159．3％、136．5％和133．9％。关键词：美洲黑杨；引种；苗期试验；成活率；生长量

| Abstract: | The experiment on cutting propagation of four clones of Populus deltoides introduced from Nanjing Forestry University revealed that among the four clones,No.895,No.797 and No.95 all had a good growth adaptability.And their seedling height and geometric vertical were obviously different from the Canadian poplar(CK).The former was 124.3%,116.8% and114.2% of CK,and the later was 159.3%,136.5% and133.9% of CK,respectively.The experiment aimed to enrich the seedling resources of the local poplar. |
