中文摘要：
选择已成功引种到北京地区的北美白云杉为研究对象，以来自加拿大的10个白云杉种源的一年生容器苗为实验材料。在温室中测定不同种源云杉幼苗的早期生长形态指标，并对其进行深入的分析，以期为探讨今后种源的苗期选择和北美云杉属植物的引种、育种和推广栽培提供理论依据。对不同种源的白云杉形态指标苗高、地径、总干重、质量指数等做了系统分析。结果表明，白云杉的不同种源间在多个指标上分别存在着一定程度的差异，其中一些指标的差异显著。初步结果认为8451592，8750062，8411488是较好的种源。
英文摘要：
In containerized this dissertation,we selected Picea glauca （10 seed sources are included）, as objects which are seedling of greenhouse of one year from different places in Canada but introduced successfully in Beijing. Physiology and stress resistance indexes of different seed source were determined in order to provide academic basis about selecting of seed source in the seedling and introduction, breeding and spread planting of picea from north America In the paper, firstly, Picea distributing and research development in the world of Picea glauca were introduced briefly, which are the most important lumber species in north America. secondly ,we studied some morphology indicator including seedling height, seedling diameter, diameter biomass, root biomass, total biomass, quality index. The results indicated Picea glauca of different seed sources had differences in a certain extent. Three seed sources, which are 8451592,8750062 and 8411488 respectively, were believed better than other resources.
