Abstract：In order to analyze the surface color characteristics in different parts of flue-cured tobacco in southwest tobacco-growing area,the quantitative analysis on surface color of flue-cured tobacco in 20 tobacco-planting counties was conducted using L * a* b * color space characterization method.The results showed that the brightness (L*) and yellowness (b *) of the lower leaves were the highest,and the reddishness (a*) of the upper leaves was the highest.The central leaves had the largest variation on tobacco surface color feature parameters.Along with the rise of leaf position,the brightness (L*) and yellowness (b *) of flue-cured tobacco decreased gradually,while the reddishness (a *) increased.There were significant or very significant positive correlation between brightness (L*) with yellowness (b*) and color saturation (C*),while very significant negative correlation with reddishness (a*) in southwest tobacco-growing area.
