Abstract:  In order to clarify the relationship between color parameters of tobacco leaves and the curing characteristics,changes of color parameters and curing characteristics of upper leaves of flue-cured tobac co NC55 and NC102 with harvesting time were studied.The correlation and regression analyses of color parameters with yellowing index and browning index were carried out.Curing characteristic regression models based on color parameters of tobacco leaves were established and tested.Results showed that,with the passage of harvesting time,the color parameter L value(brightness value) ,b value(yellowness val ue) ,C value(saturation value) of flue-cured tobacco leaves of varieties NC55 and NC102 increased in a whole,H°value( color phase angle) tended to decrease totally,a value (redness value) decreased first and then increased.The yellowing index increased,and the browning index decreased first and then in creased.The curing characteristics at a certain stage were better than those in other stages.Color parame ters had extremely significant or significant correlation with yellowing index and browning index,and the curing characteristic regression models based on color parameters of tobacco frontal leaves had better pre diction effect.It was feasible to establish a regression model based on the color parameter of tobacco fron tal leaves to predict curing characteristics.

摘要: 为明确烟叶颜色参数与烘烤特性的关系,对烤烟品种NC55和NC102上部叶正、背面颜色参数和烘烤特性随采收时间的变化规律进行研究,对烟叶颜色参数与变黄指数、变褐指数进行相关性分析和回归分析,基于烟叶颜色参数建立变黄指数、变褐指数回归模型,并对其进行检验。结果发现,随烟叶采收时间的推移,烤烟品种NC55和NC102烟叶正、背面的颜色参数L值(亮度值)、b值(黄度值)和C值(饱和度值)总体上呈不断增大的趋势;H°值(色相角值)则大体上呈不断减小的趋势;a值(红度值)呈先减小后增大的趋势;变黄指数呈增大趋势,变褐指数呈先减小后增大的趋势,存在某一阶段的烘烤特性好于其他阶段的现象。烟叶颜色参数与变黄指数、变褐指数呈极显著或显著相关,基于烟叶正面颜色参数建立的变黄指数、变褐指数回归模型预测结果较好,基于烟叶正面颜色参数建立的回归模型预测烘烤特性可行。
