高寒地区国外用材树种引种驯化及早期评价

Introduction,Domestication and Early Evaluation of Foreign Wood Species in Cold Area

遵循森林植物引种驯化供种区与引种区环境条件相似的原则,根据引种区气候、土壤、植被分布、地形地貌及地理位置等主要环境条件,确定与之相适宜的北美洲和欧洲作为供种区。以北美白云杉[Picea glauce(Moench)Voss.]、欧洲赤松(Pinus sylvestris Linn.)和欧洲白桦(Betula pendula Roth.)3个树种为引种对象,在引种驯化及区域试验的基础上,系统开展国外用材树种子代生长节律和适应性分析,并对其早期生长性状进行综合评价,旨在丰富中国高寒地区用材林树种资源的遗传多样性,以促进林业生态体系和产业体系建设。

In order to enrich the resources of wood species in the cold area,develop variety of the creature and accelerate the construction of ecological and industrial system,North American and Europe were selected as the seed zone following the resemble environmental conditions between the seed zone and introduction area.Picea glauce（Moench） Voss.,Pinus sylvestris Linn.,and Betula pendula Roth.were selected to be analyzed;and their growth rhythm,adaptability and early growth traits was evaluated.
