摘要
历时16a(1982～1997),从北京地区毛白杨基因资源调查收集开始,经苗期测定、林期测定、速生无性系选择、形质调查和木材材性测定,选育出11个不飞絮毛白杨雄株行道树优良无性系.其具有不飞毛、速生丰产、干形通直、树形美观、抗病虫能力强、材性优良等特性,适合于华北平原城乡生态环境建设和短周期工业用材林培育中推广.
Eleven non catkin male alee tree superior clones were selected through gene resources investigation and collection, sapling test, stand test, clonal selection on fast growing, quality investigation and wood property analysis of \%P.tomentosa\% in Beijing after 16 years research work from 1982 to 1997. The selected clones are suitable to ecological environmental construction and short rotation industrial timble planting in north China plain with the characteristics of non catkin, fast growing, straight bole, beautiful tree shape, high resistance to diseases and pests, and superior wood properties.
