摘要
介绍了窄冠杨树新品系A118、钻×俄、斯×施的物候、抗寒、抗病虫、形态特征等指标,并对其抗寒性进了室内测定,揭示了窄冠杨树的生物学特性,为新品种的推广应用提供了科学依据。
The phonological phase, cold resistance, insect and disease resistance and morphology characteristics about new clones of poplar such as Populus simonii × P. popularis , P. pyramedalis ×P. russkii and P. stalirtetz × P. vernirniubens was researched. Meanwhile, in cold resistance was measured in laboratory, and brought to light the biological characteristics of narrow crown polar. research project, which provides scientific basis spreading new clones.
