通过观测27个木槿品种的17个数量和质量性状,探究了木槿品种分类的等级和标准,便于为木槿品种的选育与资源研究等提供参考依据。首先对17个性状指标进行R型聚类分析和主成分分析,根据分析结果再对27个木槿品种进行Q型聚类分析。R型聚类分析结果表明,各性状选取是合理的;主成分分析结果表明,17个性状可综合为6个主成分,其累计贡献率达88.096%。Q型聚类结果表明,27个木槿品种根据有无丹心、花型、丹心基部形状、花瓣指数、花径、叶形、丹心线与丹心的关系可被分为2大类、3大类或8大类。16个性状对木槿品种的划分贡献较大。综合而言,有无丹心、花型、花瓣指数、丹心线与丹心的关系是木槿品种分类的...

Through observing 17 quantity and quality traits of 27 hibiscus varieties, the classification grades and standards for Hibiscus syriacus cultivars were studied, so as to provide reference basis for breeding and resource research of H.syriacus cultivars. At first, studies on 17 characters data were conducted with R-type cluster and principal analysis. Then, according to the results of R-type cluster, 27 hibiscus cultivars were classified with Q-type cluster. R-type cluster analysis proved that the selection of each trait was reasonable. Principal component analysis showed that 17 traits could b...
