摘要
对5个北美兰云杉优良种源进行了引种苗期试验研究,认为种源的苗高、地径生长量均差异显著,说明种源之间存在着真实的差异,优良种源的选择是有效的。今后生产上应用入选的优良种源生产的种子可获得显著的增产效果。
Trials on seedling stage of introducing five fine provenances ofPicea pungens Engelm. have been done. The results show that there are significant differences in seedling heights and diameters, which proves that real differences exist among provenances and it is effective to choose good species.
