| 摘 要： | 利用嘉汉林业有限公司黑木相思项目组选育出的黑木相思无性系,测试这些无性系在3个不同地点(广东河源、高要和广西百色)的早期生长表现,并据此进行早期选择。结果表明:在不同地点各无性系的生长表现各不相同;按照30%的淘汰率,每个地点选出13～14个表现比较好的无性系,树高和胸径生长量比对照高出10%～48%,其中无性系SR24、SR3、SR6、SR22同时在参试的三个地点表现都较好,而SR13、SR24、SR3、SR8、SR6、SR10、SR22这七个无系性则在广东的两个地点表现较好。

| Abstract: | The blackwood project team of Sino-Forest Co. Ltd. selected dozens of Acacia melanoxylon clones. The growth performance of A. melanoxylon clones was tested in three different sites （Heyuan and Gaoyao of Guangdong province, Baise of Guangxi province）. Based on that, early selection was performed on those clones. The results showed that the clones growth varies depending on different sites. Under the 30% elimination rate, 13 to 14 clones were selected in each site, which height and DBH （diameter at breast height） in average were 10% to 48% higher than the others. Four clones （SR24, SR3, SR6 and SR22） appeared simultaneously in all three sites and seven clones （SR13, SR24, SR3, SR8, SR6, SR10 and SR22） had good growth performance in both sites of Guangdong. |
