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%。The experiment on cutting propagation of four clones of Populus deltoides introduced from Nanjiag 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% andl14.2% 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.
