本文分析了引自澳大利亚东部的伞房属4个树种在广东省的早期生长表现。3年生及5年生4个树种生长量的方差分析表明，不同地点、树种及地点与树种的交互作用在树高、胸径、材积生长量上均表现出极显著的差异。3年生时，生长表现最好的是斑皮柠檬桉，平均单株材积0.007191m3；德庆试点的生长表现是4个试点中最好的，4个树种的平均单株材积为0.01557m3。5年生时，生长表现最好的是大叶斑皮桉，平均单株材积0.04216m3；德庆试点的生长表现是3个试点中最好的，4个树种的平均单株材积为0.06889m3。

Abstract: |
|
Study on 4 species of Corymbia introducted from eastern Australia was conducted. Two mixture seedlots of Corymbia citriodora ssp. citriodora from Guangdong Province were selected as controls. Height growth, diameter at breast height (DBH) and single-tree volume have most significant differences among sites, species and site×species．The results of 3 years′ trial were summarized as follows: C. variegata was the best species, its mean single volume was 0.007191m3. The growth performance of Deqing was best. The results of 5 years′ trial in were summarized as follows: C. henryi was the best species, its mean single volume was 0.04216m3. The growth performance of Deqing was best.
