摘要
以15个桉树(Eucalyptus spp.)无性系为研究对象,调查2.5、3.5、4.5年生无性系试验林的胸径和树高,研究其生长性状。结果表明,历年胸径、树高和单株材积在无性系间存在极显著差异。根据4.5年生的生长量分析,基于Q型聚类初步筛选出6号、8号和14号等3个优良无性系,它们的生长量均达到甚至高于对照的生长量。本研究可为该地区无性系进一步选育和应用提供依据。
15 Eucalyptus clones were selected as the research objects. The DBH and tree height of the 2.5-year-old, 3.5-year-old and 4.5-year-old were investigated to study their growth characteristics. Results showed that there were extremely significant differences in DBH,tree height and individual volume over the years. According to the growth analysis of 4.5-year-old,such three superior clones as No.6,No.8 and No.14 were preliminarily selected based on Q-type clustering,and the growth of the three clones could reach or even exceed the growth of the control,which provided the basis for further breeding and application of clones in Nannning area.
