1、不同香型烤烟表面颜色特征分析摘要：为揭示不同香型烤烟表面颜色特征，采用L*a*b*C*颜色空间表征方法对14个省份三种香型烤烟不同部位烟叶表面颜色进行量化分析。结果表明：①烟叶表面颜色红度讲在浓香型和中间香型烤烟中变异程度较大，中间香型烤烟表面颜色的饱和度C*变化幅度大于浓香型和清香型烤烟。②中间香型烤烟表面颜色的明度L*最大，在中部叶和上部叶显著高于清香型烤烟；清香型烤烟下部叶表面颜色的红度a*显著高于浓香型和中间香型烤烟。颜色饱和度C*在不同香型烤烟间不存在显著性差异。③同一香型烤烟表面颜色均呈现下部叶的明度U最高，上部叶的最低，且在不同部位间存在显著性差异，同时，同一香型

2、烤烟表面颜色的红度a*均表现为上部叶最高，下部叶最低。④浓香型烤烟表面颜色的红度a*与黄度b*、颜色饱和度C*呈极显著负相关，而清香型和中间香型的相关性都很小。本文采集自网络，本站发布的论文均是优质论文，供学习和研究使用，文中立场与本网站无关，版权和著作权归原作者所有，如有不愿意被转载的情况，请通知我们删除己转载的信息，如果需要分享，请保留本段说明。关键词：烤烟；香型；表面颜色特征中图分类号:S572.01文献标识号:A文章编号：1001-4942(2017)07-0034-04AbstractToexplorethesurfacecolorcharacteristicsofd
