摘　　要：以42个县(区)的C3F等级烤烟为材料,探究其颜色参数与质体色素等颜色指标的关系,并区分不同产区烟叶颜色特征.结果表明:1)H°与颜色指标的相关性较差,其余指标之间的相关性均达到显著水平以上;2)不同产区烟叶在颜色指标主成分图中的分布差异明显,但不同种植区的分布呈一定规律性;3)聚类分析将各产区烟叶样品分为4类,且类别间颜色差异明显.因此,从颜色角度判别烟叶产地具有可行性.Flue-cured tobacco leaves(C3F) from 42 counties was used as experimental materials to explore the relationship between color parameters and plastid pigment and other color indicators and to distinguish the color characteristics of tobacco leaves in different producing areas. The results showed that: 1) The correlation between H° and color index was poor, but the correlation between other indexes reached a significant level;2) There were significant differences in the distribution of color index principal component diagram among different producing areas. But the distribution of different planting areas showed a certain regularity;3) The samples of tobacco in different production areas were divided into four categories by cluster analysis, and the color difference among the different categories was obvious. So it is feasible to distinguish tobacco producing area by colors.
