| 摘 要： | 对长白落叶松初级种子园优树子代测定林(19年生)37个家系的树高、胸径和立木材积进行分析的结果表明:树高、胸径、材积均差异极显著,且生长性状之间呈显著正相关关系。以材积性状作为主要指标,同时兼顾树高、胸径指标,对参试家系进行选择,选出10个优良家系。

| Abstract: | The height,diameter at breast height and volume of 37 families from 19-years-old progeny testing forests of Larix olgensis primary seed orchard were analyzed.The result showed that there were greatly significant variations in these three characters among these families.Moreover,the height,diameter at breast height and volume was in very significant positive correlation.10 superior families with good growth performance were selected from 37 openly pollinated families mainly according to standing volume in co... |
