摘要
泡桐胶合板材培育的4组栽培性状(生长性状、干形性状、接干性状和树冠性状)的典型相关分析表明,它们之间存在着不同显著程度的典型相关,其中的接干性状与树冠性状组显著相关的信息占两组性状间总信息的95.1%,是相关程度最高的一组性状。泡桐21个无性系在上述性状上,存在不同程度的差异。
groups of cultionation charaters of plywood in 21 paulownia clones have been studied by means of canonical correlation analysis.The results show that there exist varying correlations between the 4 groups of characters.The correlation of trunk extension character and that of tree crown character are the highest in all character groups. Much difference exists in the characters of growth,stem form.trunk extension and tree crown in the 21 Paulownia clones.
