烤后烟叶表面颜色特征参数及其与外观质量指标的关系
The relationship between the characteristic parameters of surface color and the index of appearance quality of flue-cured tobacco
摘要
Abstract
In order to study the relationship between the surface color characteristic parameters and the index of appearance quality of flue-cured tobacco,variety CB-1,K 326 and Yunyan87 were taken as materials for the field experiments.The results showed that:1) With the leaf-position rising,the L* value decreased,the a* value increased,the b* value increased at first and then decreased,reaching the highest at 7 ~ 10 leaf-position,similar to the change of C* value.The variance of the surface color characteristic parameters of flue-cured tobacco was significant between stalk portions;2) the color characteristic parameters of base-color was different.The b* value and the C* value of orange tobacco leaves were generally higher than that of the lemon and red brown tobacco leaves.The L* value of lem on tobacco leaves was the highest.The a * value of red brown tobacco leaves was the highest;3) the surface color characteristic parameters of flue-cured tobacco were significantly or extremely significantly correlated to the index of appearance quality.There was an obvious " (n) "-shaped curve between the L* value,the a* value and the total value of appearance quality evaluation.When the L* value was 53 ~ 54 or the a* value was 13 ~ 15,the total value of appearance quality evaluation reached the high est.There was a significant positive correlation between lightness and oil,and a significant positive correlation between yellowness and total score.关键词
