摘　　要：以青冈栎42个半同胞家系2年生苗为研究对象,对其苗高生长和地径生长进行测定分析与比较。结果表明:青冈栎不同家系间苗高生长和地径生长差异极显著。综合苗高生长与地径生长性状,进行Duncan分析表明:青冈栎39、27、28、19号等4个家系为苗期生长表现优良的家系。By taking 42 half-sib families of Cyclobalanopsis glauca as the research objects,the seedling height and basal diameter of two-year-old Cyclobalanopsis glauca were investigated and compared.The results showed that,there were highly significant differences in seedling height and basal diameter among the families.According to the characters of seedling height and basal diameter,by using Duncan multiple comparison,No.39,No.27,No.28 and No.19 families of Cyclobalanopsis glauca were selected as the superior families during seedling stage.
