对桉属６个树种在广东省４年生时单位面积蓄积量进行３个试验点的点内和多点的方差分析，用新复全距（ＳＲ）检验法进行显著性测验。结果表明，桉属同一树种在不同试验点上，不同树种在同一试验点上均有显著差异．树种与试验点间交互作用明显。尾叶桉和细时桉在３个试验点上有较高的蓄积量，其单位面积蓄积量比当地主栽树种窿缘桉高３２．９％─２４７．９％，是值得推广的优良树种。
Point-to-point and multi-point analysis of variance (ANOVA) of three test points in 6-year-old eucalyptus trees in 4-year-old Guangdong Province was conducted. The significance test was carried out by SR test. The results showed that the same species of Eucalyptus at different test points, different species at the same test point were significantly different. Interactions between tree species and experimental sites are obvious. Eucalyptus urophylla and Eucryptopus cinnabarinus had relatively high stock volume at three test sites, and their stock volume per unit area was 32.9% -247.9% higher than that of the local main species of tree eucalyptus, which is worthy of promotion .
