| 摘 要： | 以3个试点53个家系的大叶栎试验林为研究材料,分析了4年生大叶栎家系间的生长差异,结果表明:(1)家系对苍梧试验点的胸径生长无显著影响,对苍梧试验点的材积生长有显著影响,对苍梧试验点的树高生长和黄冕、派阳山试验点的树高、胸径和材积生长均有极显著影响。(2)初步选出的10个优良家系平远11、通道09、融水05、明溪05、融水01、平远01、融水09、融水04、苍梧05和融水08,综合评定值最高的家系平远11的胸径、苗高和材积分别为未入选家系平均值的1.21倍、1.08倍、1.61倍,分别为最差家系苍梧07的1.84倍、1.42倍、5.01倍。

| Abstract: | The article analyzed growth difference among fiftythree Castanopsis fissa families at the age of 4 in three trial sites.The results showed that:(1) there weren't significant effects on the DBH of Castanopsis fissa in the experiment site of Cangwu,but there were significant effects on the volume of Castanopsis fissa in Changwu and extremely significant effects on the height in Cangwu and on the DBH,height,volume in the other experiment sites;(2) Ten superior families were selected,and the best family was Pin... |
