摘要
以马大杂种相思9个无性系为研究对象，采用方差分析、相关性分析和模糊数学中的隶属函数系统分析了马大相思无性系生长、干形及叶片性状等18个指标的差异。结果表明：树高、胸径、干形、树皮厚度及叶片密度在无性系间均存在显著或极显著差异，无性系间各性状变异系数为4．39％～70．92％，初步筛选出8、6、3和1号共4个综合表现优良的无性系。
By analysis of variance,correlation analysis and synthetically membership function in fuzzy mathematics,the variation of 1 8 phenotypic traits （including the growth,stem and leaf traits）of 9 clones of Acacia mangium ×A.auriculiformis were analyzed.The results showed that there were significant differences among 9 clones of A.mangium ×A.auriculiformis in tree height,DBH,stem,bark thickness and leaf density.Main char-acters variation coefficients among different clones varied from 4.93%to 70.92%.No.8,6,3 and 1 clones were preliminarily considered as superior cultivated varieties.
