摘　　要：以10个黑杨杂种候选新品系为试验材料,以当前优良品系108杨和中林46杨等为对照,通过室内和大田水分胁迫试验,同时结合在不同生态区内区域化试验及测定无性系的遗传特性(生长、材性和纸浆性能等),以水分利用效率、产量、材质等指标对候选品系进行综合比较分析,获得了木材纤维长、纤维含量高、木素和1%NaOH抽提物含量低的节水资源高效利用型杨树优良纸浆材新品种J2和J6,为华北、西北地区选育了抗旱、耐盐碱的优良杨树品种。In this study, 10 hybrid clones of Section Airgeiros were used as plant material and current excellent varie- ties P. x euramericana Guariento＇ and P. x euramricana （Dode） Guineir cv. ＇ zhonglin-46＇ as controls, two new ex- cellent Populus pulpwood varieties J2 and J6 were selected through indoor and outdoor water stress trials, genetic characters（ growth, wood properties and pulp yield etc. ） of regional trials in different ecological areas, and integrat- ed analysis of WUE, yield and wood qualities. J2 and J6 had the characteristics of long-fiber, higher holocellulose, lower lignin content and 1% NaOH extractives, which filled in the blank of drought- and salt-resistant poplar breed- ing in north and northwest China.
