| 摘 要： | 采用“五株优势木”法评选黑木相思（Acacia melanoxylon）优树，采集优树根蘖萌芽条进行扦插和组织培养繁殖无性系试验苗。采用随机区组试验设计，在广东省紫金县苏区镇进行无性系测定，利用黑木相思4 a生的树高、胸径等观测数据进行无性系早期评价，结果表明，18个参试无性系中有12个无性系的树高生长或胸径生长显著优于对照（P＜0．05），可作为与试验点类似条件地区中试推广的无性系。

| Abstract: | This paper deals with the clone selection of Acacia melanoxylo at Suqu town,Zijin county, Guangdong province.Plus trees were selected by the comparison of Five-Elite-Trees.Clonal seedlings were propa-gated by cutting and tissue culture,using root sprout of plus trees as materials.The experimental design of clone trial was random block design.Early clone evaluation was based on variation analysis of DBH and tree height at four years old.The results showed that the DBH growth or height growth of twelve clones were significantly bigger than that of the control,and these fine clones would be suitable for further large scale experiments and extension in the region with similar climate as the experiment site. |
