摘　　要：对杂交选育和引种的9个杨树无性系进行扦插试验,结果表明：不同无性系的苗期地径、胸径和苗高生长量存在极显著差异,其中黑小2号、J10、J7等3个无性系表现最优,地径、胸径、树高分别较小黑杨提高45.03%～22.16%、70.99%～14.96%、44.31%～16.43%。Cutting experiments of introduced hybridization breeding clones of nine poplars were conducted .Result shows that ：ground diameter ,DBH ,seedling height （H） of different clones at the seedling stage have very significant differences ;the seedling growth of P .nigra＆#215; P .simonii ,J10 ,J7 are optimal ,the ground diameter ,DBH ,tree height increased by 45 .03%-22 .16% ,70 .99%-14 .96% ,44 .31%-16 .43% than that of P .simonii＆#215; P .nigra .
