沙松纸浆用材林不同家系苗期生长差异比较

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。

Growth Differences in Seedling Stage of Different Families with Pulpwood of Abies holophylla

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.
