| 摘 要： | 对湖南泸溪葡萄桐在鄂南栽培条件下的１０个表型性状进行了主成分分析一分类。结果表明，前５个主成分的累计贡献率达８０．９％。根据主成分的因子负荷量及其主要指标组合，将１０个生物学性状分为３类，分别称之为冠形因子，花序因子，枝梢因子。主成分分析说明了这３类因子对油桐的作用。

| Abstract: | Ten biological characters of Tung oil tree Vernicia fordii(Hemsl.)Airy-Shaw have been studied by meams of the principal components analysis and classification. Result manifested:The additive contributing rate of the first five principal components amounts to 80.9%.According to the information ot loading and the compose of main target of the principal components,the 10 biological.characters could be divided into 3 grups:crown form factor; Inflorescence factor; Branch and shoot factor.The principal components analysis has illustrated the effect of these 3 group factors for Tung oil tree. |
