摘要
利用来自欧洲的13个欧洲赤松(Pinus sylvestris)种源,以当地的樟子松(Pinus sylvestris var.mongolica)作对照开展了试验.结果发现,1a生苗木能否正常越冬成为评价种源好坏的首要因子,比利时、奥地利、法国等西欧种源生长较快,但不能正常越冬;瑞典、芬兰等北欧种源基本能正常越冬,但生长迟缓,潜力不大;波兰、爱沙尼亚种源1 a生苗的越冬保存率在80%以上,2 a生苗生长量与樟子松相仿且均能安全越冬,为适宜种源.
A provenance test including 13 European seed sources and 1 local seed source of Pinus sylvestris was carried out in nursery in Zhanggutai, Liaoning Province. Results showed the over wintering capability of yearlings was a primary index to assess the seed sources. The seed sources from Western Europe such as France, Belgium and Austria grew fast but could not survive in winter. The seed sources from Northern Europe such as Sweden and Finland grew rather slowly, and had no potential of high production, although their yearlings survived winter well. The Polish and Estonian seed sources not only survived winter well but grew so fast as Pinus sylvestris var. mongolica that they were suitable for the area.
