摘    要:应用两阶段聚类法对云南省大理州14个主栽烤烟品种C3F和C3L 2个等级的中部烟叶外观质量进行聚类分析,并应用多元方差分析对聚类效果进行了检验.结果表明,产地和品种对烤烟外观质量的影响较小,并将100 个烤烟样品外观质量分为3 个类型;明确了各类型烟叶外观质量的重要性状、变异特点和类型间的分类特性;其聚类分析结果与烤烟外观质量的实际表现相吻合,因而两阶段聚类分类结果客观、合理、准确、可靠.

关 键 词:烤烟  外观质量  两阶段聚类分析

Abstract:The appearance quality of flue-cured tobacco leafs of 14 main planted varieties in Yunnan Dali were analyzed by using the two-step cluster method.Based on the result,the appearance quality of flue-cured tobacco leafs were less affected by vary zoology spots and different varieties.The 100 samples of flue-cured tobacco leafs were divided into 3 clusters.This method defines the important characteristics in a cluster and the classification among types.The conclusion is objective,reasonable and reliable,coincid...
Keywords:Flue-cured tobacco  Appearance quality  Two-step cluster analysis
