摘要：对20个桉树无性系的生长性状、形质性状进行差异分析和综合评价,结果表明:各性状在无性系间差异均极显著,各性状的无性系重复力为61.46%～93.84%,在较大程度上保持着年度间的持续稳定.各生长性状间均呈紧密的表型、遗传和环境正相关关系,形质性状中仅分枝与生长性状呈紧密的负相关关系.5.5年生最优无性系TH9113单株材积达0.092 08 m.3,是最差无性系CP01的407.80%,是所有无性系均值的196.29%;无性系TH9510形质性状表现最优.应用主成分分类方法将参试无性系分成4类,速生类材积是慢生类的264.99%,增产效果十分显著.
The 20 Eucalyptus clones test analyzed results involving 5 species showed that there were highly significant differences in growth and other characteristics among clones. Repeatability of clones and individual retained the stable level at different ages with 61. 46%～93. 84% and 28.51%～79. 19% for different characteristics studied, respectively. There were closely phenotypic,genetic and environmental correlation among H,DBH and SV each other. Branch size （BR） had significant negative correlation with growth characteristics. At an age of 5. 5 year old, the mean value of individual volume （SV） of the fastest clone （TH9113） （0. 092 08 m^3） was 4. 078 0 and 1. 962 9 times of the worst clone （CP01） and the whole population （all clones）,respectively. All clones were categorized into 4 classes by using principal component analysis,and the fastest class was 264. 99% higher than the lowest class with a obvious level of productivity increasing.
