摘要
在雷州地区进行的赤桉种源试验结果表明：种源间的树高、胸径生长差异达极显著水平；单位面积产量最优种源的为最差种源的２７．７倍；来自澳大利亚低纬度的种源较适生于引种地，来自澳大利亚高纬度、泰国及四川的种源则不适于引种地生长。
The provenance trial of Eucalyptus camaldulensis was carried out at Leizhou,Guangdong province.The performances of these provenances indicated that the growth variation in both height and breast-diameter were significant and the yield from the superiority was 27.7 times as high as that from the poorest.The provenances from low latitudes area of Australia acclimatized to the circumstance of Leizhou,those from high latitudes of Australia,Thailand and Sichuan in China didn't.
