摘要
通过对引进的挪威云杉种源和窄冠垂枝型挪威云杉家系进行不同地点苗期试验,选取生长期、当年高和存活率等3个指标进行苗期生长适应性评价,研究结果表明,部分窄冠垂枝型挪威云杉家系具有良好的生长适应性,大部分存活率相对比较低,挪威云杉种源苗期生长普遍不能适应。
Experiments of Picea abies provenances and narrow crowned pendula Picea abies families introduced from Finland were conducted in different plots. The growing season, the present-year height growth, survival rate were selected to evaluate growth adaptability in seedling stage. Result shows that ： narrow crowned pendula Picea abies families introduced from Finland have growth adaptation;the most survival rate is relatively low;Picea abies provenances in the seedling stage can＇t adapt to the local latitude.
