| 摘 要： | 对巨桉家系生长性状、形质性状等的遗传分析表明 ,巨桉家系间在胸径、树高、材积和冠幅方面存在着很大的生长差异 ,各生长性状遗传相关极显著。通径分析进一步揭示胸径是构成巨桉单株材积的最主要因素。

| Abstract: | The results of E grandis involved 145 families at the age of 5 years showed that there were highly significant differences among families at the growth characters of DBH, height, volume and crown, and there were highly significant positive genetic correlations with the growth characters. The path analysis revealed further that DBH was the most important element to volume of E grandis individuals. |
