对从老挝、中国海南、缅甸选出的柚木优树进行组培，并培育出23个无性系苗木，以中国海南柚木种子园1个家系的实生苗作为对照，开展柚木的山地造林试验，在造林30个月后对幼林的树高、胸径生长量、保存率、枯梢率进行了测定与分析。研究结果表明：不同的柚木无性系在高、径生长上均存在着极显著差异，表明开展柚木优良无性系选择十分必要；综合柚木的生长量及适应性看，表现较好的无性系为2号、24号、22号；入选的无性系高、径生长量及适应性均优于种子园的实生苗，可作为当地造林的繁殖材料。

With the tissue culture from Laos, Hainan Province of China, Burma elected superior tree of Tectona grandis, we conducted the mountain afforestation experiment by using cultivation 23 clonal seedlings and seedling of one family in Tec-tona grandis orchard of Hainan (as control), and analyzed their tree height, DBH increment, preservation rate and dry treetop rate after 30-month plantation.Different clones in height and diameter growth are significant differences, indicating that the selection is necessary about excellent clones of Tectona grandis.By the integrated views in growth and adaptability of clones, No.2, 24 and 22 are with good performance.Selected clones in high, diameter growth and adaptability are bet-ter than seedling in orchard, and can be used as local propagation material in afforestation.
