摘要:
 为对核桃主要经济性状进行综合评价。应用主成分分析法,由样本相关矩阵出发,对滇东北地区决选7株核桃样本的7个主要经济性状(三径平均值、坚果重、种壳厚、种仁重、出仁率、含油率、单位面积(m2)树冠投影产仁量)进行分析。以性状的累计方差贡献率达到 92.617%为标准,确定了3个反映核桃主要经济性状的主成分及其主成分的函数式,并通过计算优株的重要主成分值,对供试优株进行比较和排序,其结果与实际表现相符。证明了主成分分析法在核桃优树综合选择中的应用价值。
Abstract:
 In order to conduct comprehensive evaluations on major economic characters of walnut occurring in northeastern Yu-nan,based on correlated matrix,principal component analysis was adopted to analyze seven major economic characteristics (including average of three kinds of diameters,nut weight,shell thickness,kernel weight,kernel ratio,oil rate,and kernel weight yield per square meters of projected tree crown area) collected from 7 superior sampling strains.Three principal components,in which the rate of contribution of the accumulative variance were 92.617%,as well as their functional equations were established.Through the calculation of the values of important principal component,superior strains were ranked and compared.The theoretical results were verified with practical indices.It proofed that the principal component analysis was a suitable method for the comprehensive selection of superior walnut strain.
