| 摘 要： | 利用SPSS软件对17个薄壳山核桃无性系10个果实性状指标(果重、果高、果径、果型指数、果皮厚、核重、核高、核径、核型指数以及出核率)进行了主成分分析、聚类分析.结果表明,前3个主成分就能概括所有性状98.47％的信息.利用这3个主成分值对17个薄壳山核桃无性系进行系统聚类,在欧式距离为10时,无性系12号、17号、6...

| Abstract: | Principal component analysis and clustering analysis were applied to analyze 10 fruit character indices(fruit weight,fruit height,fruit diameter,fruit shape index,peel thickness,nut weight,nut height,nut diameter,nut shape index,nut weight in fruit) of 17 Carya illinoemis.The results indicated that,the first 3 principal components can explain 98.47% of 10 characters.Systematic clustering analysis using the 3 components as variants,when the euclidean distance was around 10,clone fruit no.12,17,16,3,1,5,4,13,... |
