摘要:Taking F1 generation of male clones of new hybrid varieties -- Populus euramericana "N3016" × Populus ussuriensis as object, its growth & resistance were investigated. Result shows that : average tree height, DBH & volume of individual plant of 11-year-old Populus euramericana "N3016"× Populus ussuriensis are 15.05 m, 16.19 cm & 0. 142 m3 in Qiqihar region, which exceed 8.6%, 14.8% & 37.2% of control varieties of Populus simoniixP, nigra, respectively. Populus euramericana "N3016"× Populus ussuriensis have strong resistance to major diseases (grey leaf-spot, rust disease, Vaisa sordida Nits. , Botryosphaeria ribis (T ode) Grossenb. et Duggar) and the main stem-borers (Saperda populnea, Cryptorrhynchus lapathi L. , Rhynchaenus empopulifolis Chen. ). This variety whose male plants didn' t flutter, is straight & plum- ping, and is suitable for pulpwood and other industrial timbers, sheherbehs and afforestation species.%研究以杂交新品种黑青杨(Populus euramencana“N3016”×Populus ussuriensis)F1代雄性无性系为对象,对其生长、抗性进行了调查,结果表明,在齐齐哈尔地区11年生黑青杨单株平均树高、胸径和材积分别为15.05m、16.19cm和0.142m^3,分别超过对照品种小黑杨8.6%、14.8%和37.2%。对主要病害杨灰斑病、锈病、烂皮病、溃疡病及主要蛀干害虫青杨天牛、杨干象、潜叶跳象等抗性较强。该品种树干通直饱满,雄株不飞絮,适合作纸浆材等工业用材林、防护林及绿化树种。
