采用方差分析和聚类分析的方法对毕节地区2005～2006年431份烤烟烟叶样品进行感官质量评价,结果表明:毕节地区多数烟叶样品感官质量较好,部分烟叶样品感官质量稍差;除灰色(差异达0.05显著水平)以外,感官质量其它各项指标在各县(市)之间的变异达到0.01的极显著水平。根据感官质量总分聚类,可以分为3类:黔西县、金沙县和织金县为第1类,感官质量稍差;毕节市、大方县、纳雍县和赫章县为第2类,感官质量较好;威宁县为第3类,感官质量最好。
The sensory evaluation of 431 samples of flue-cured tobacco leaves from 2005 to 2006 in Bijie Prefecture was conducted by means of analysis of variance and cluster analysis. The results showed that the sensory quality of most of the tobacco samples in Bijie Prefecture was better than that of the other samples, The differences were significant at the level of 0.05). The variability of other indexes of sensory quality among counties (cities) reached the extremely significant level of 0.01. According to the total score of sensory quality, clustering can be divided into three categories: Qianxi County, Jinsha County and Zhijin County belong to the first category, with less sensory quality; Bijie, Dafang County, Nayong County and Hezhang County are No. 2 Class, sensory quality is better; Weining County is the third category, the best sensory quality.
