Analysis on Fresh Tobacco Leaf Color Parameters and Flue-curing Characteristics and Their Correlation
摘要
Abstract
In order to clarify the relationship between fresh tobacco leaf color parameters and flue-curing characteristics of the flue-cured tobacco variety K326,we used middle and upper leaves of K326 as experimental materials,and set three maturity levels(under-ripe,well-ripe and over-ripe)to extract color characteristic values of tobacco leaves by image acquisition systems,including R(red value),G(green value),B(blue value),H(hue),S(saturation),and V(brightness).The yellowing and browning times of tobacco leaves at different maturity levels were obtained using a darkroom method to analyze their flue-curing characteristics.The relationship between color parameters and flue-curing characteristics was explored through correlation analysis,and regression models were established for validation.The results showed that as the maturity of tobacco leaves increased,the R,G and V values of middle and upper leaves tended to increase,while the H value decreased.There were no significant changes in the B and S values of upper leaves.The yellowing and browning times of tobacco leaves shortened with increasing maturity,with the middle leaves generally had longer yellowing and browning times compared with the upper leaves.The R and H values of middle leaves were significantly correlated with yellowing time,and all color parameters were significantly correlated with browning time.The G and V values of upper leaves were significantly negatively correlated with yellowing time,while the correlations between R,G,B,H,S and V values and browning time were not significant.After validation through regression model fitting,all R2 values were greater than 0.85,indicating it was feasible to infer flue-curing characteristics of tobacco leaves using color parameters of middle and upper leaves.关键词
