摘要: 泡桐4组栽培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个无性系在生长、干形、接干和树冠性状上,存在不
同程度的差异。
Abstract:4 groups of cultival characters related to plywood making of 21 paulownia clones were analysed using canonical correlation analysis.The results showed that there were different degrees of correlation among 4 group characters.Correlation degree between trunk extension characters and tree crown characters was the highest in all character groups.Variations at different level in growth character,stem form,trunk extension and tree crown were found among 21 paulownia clones.
