| 摘 要： | 目的]掌握云南文山不同烟区的烤烟主要化学成分协调性差异情况。方法]利用随机取样的方法采集7个县(市)的烤烟样品,采用指数和法对其主要化学成分含量进行赋值评分,并进行差异性分析和系统聚类。结果]文山烟区烤烟常规化学成分之间有明显差异,在7个县(市)中以广南主要化学成分总得分最高,且与其他县(市)呈显著差异;基于烤烟常规化学成分的聚类分析,7个县(市)烤烟样品分为3类,第一梯队为西畴、丘北、文山、广南、麻栗坡县,第二梯队为马关县,第三梯队为砚山县。结论]为烟草主要化学成分评价提供了新的思路和方法。

| Abstract: | Objective] The aim was to grasp difference of the main chemical components coordination of flue-cured tobacco in Wenshan Yunnan.Method] Flue-cured tobacco samples from 7 counties were collected by random sampling method,the main chemical components were scored by index sum method,and the difference analysis and cluster analysis were carried out.Result] The results indicated that after being scored,there were obvious differences on the conventional chemical compositions of flue-cured tobacco in Wenshan.The total score of main chemical components of Guangnan was the highest in seven counties,and showed significant difference between the other counties.Cluster analysis based on the conventional chemical components of flue-cured tobacco indicated that the flue-cured tobacco samples from seven counties were divided into three categories,the first class was Xichou,Wenshan,Guangnan,Malipo,Qiubei County,the second class was Maguan County,and the third class was Yanshan County.Conclusion] The results provide reference for main chemical components evaluation of flue-cured tobacco. |
