挪威云杉（Picea abies [L.]喀斯特。）种源从中欧（海西-苏台德地区）进行了评估，在一个长期的实验项目（德国-捷克共和国）36年后的出植。在捷克共和国的捷克-摩拉维亚高地地区的Ledeglove-Zaháj试验田上，在典型的挪威云杉栽培条件下，对64个云杉种源的生长特性、死亡率和质量形态特征进行了评价。结果表明，种源间树高和径向生长量差异在15-20%之间，干形、分支密度和形状等质量性状差异不显著，健康状况也不显著。对生产性状影响显著的环境变量有种源产地的经度、纬度和海拔，而年均气温和年均降水量对生产性状影响不显著。在试验地条件下，以北纬49-51度、东经13-20度的种源产量最高。
Norway spruce (Picea abies [L.] Karst.) provenances from Central Europe (Hercynian-Sudetes area) were evaluated in a long-term experimental project (Germany-Czech Republic) 36 years after the outplanting. The growth characteristics, mortality and qualitative morphological characteristics of 64 spruce provenances were evaluated on the experimental plot Ledeč-Zaháj, in the Czech-Moravian Highland region of the Czech Republic, in typical conditions for Norway spruce cultivation. Results show 15–20% differences in height and radial growth between provenances and insignificant differences in qualitative characteristics e.g. stem shape, branch density and shape and also health state. Environmental variables that significantly influenced production characteristics include longitude, latitude and altitude of the original locations of the provenances, while average annual temperature and average annual precipitation were not significant. Given conditions of the experimental plot, optimal production occurred with those provenances originally from 49–51 N latitude and 13–20 E longitude.
