１９８６年和１９８８年先后进行了２次澳大利亚赤桉种源的地理试验研究。试验表明，赤桉种源之间树高、胸径生长量存在着显著或极显著的差异，且各种源树高与胸径之间的相关性极强。根据高、径生长量和在极端气候条件下表现出的抗寒能力，２次试验初步筛选出３～４个生长量大、抗寒能力强的种源用于早期推广应用。通过观测，还验证了关于我省桉树最适生长区的划分。

In 1986 and 1988, two geography experimental studies on provenances of Eucalyptus grandis in Australia were carried out successively. The results showed that there were significant or extremely significant differences in tree height and DBH growth between Eucalyptus and Eucalyptus provenances, and the correlation between tree height and DBH was very high. According to the height and diameter growth and the ability to resist cold under extreme climatic conditions, three to four seed germplasms with high growth capacity and cold hardiness were screened out in two experiments for early popularization and application. Through observation, but also verified the division of the optimum growth area of ​​eucalyptus in our province.
