摘　　要：通过对东北地区10个种源的77个家系沙松纸浆用材林苗期的苗高、地径和当年高生长指标测定和分析,比较不同家系苗期生长差异,结果表明:不同家系沙松间苗高、地径、当年高生长量均存在显著差异;苗高生长表现良好的为东京城04、东京城05和柴河04号家系;地径生长表现良好的为露水河08、东京城04和柴河05号家系;当年高生长表现最好的为露水河14号家系。Through the determination and analysis of seedling height,ground diameter and current year height growth indexes of 77 families from 10 provenances of Abies holophylla at the seedling stage.Result shows that:Seedling height,ground diameter,and current year height of different families of Abies holophylla are significantly different;the families with good seedling height growth are Abies holophylla‘Dongjingcheng No.04’,Abies holophylla‘Dongjingcheng No.05’&Abies holophylla‘Chaihe No.04’families;the ground growth performance is good in Abies holophylla‘Lushuihe No.08’,Abies holophylla‘Dongjingcheng No.04’and Abies holophylla‘Chaihe No.05’families;the performanc of the very year height of Abies holophylla‘Lushuihe No.14’family is optimal.
