Abstract: Flue-curing characteristics of the new flue-cured tobacco variety NC55 introduced from abroad,which included changes of discoloration property under dark condition, pigments, water content and activity of polyphenol oxidase( PPO) were studied, with Zhongyan 100 as control, in order to find out the flue-curing characteristicsof NC55, a new flue-cured tobacco variety introduced from abroad. The results showed that NC55 performed rapidyellowing and good easy curing potential under dark condition. And the time which was from complete yellowing tocome into browning was longer of NC55 was longer than Zhongyan 100. NC55 had low speed of browing and goodendurable curing potential. The chlorophyll and carotenoid of NC55 declined rapidly, but the degradation was lowerthan Zhongyan 100 during curing. The color change during the yellowing stage of Zhongyan 100 was in accordancewith water removal. PPO activity of NC55 was lower during the early days of curing, and it would not occur browningreaction. Appearance quality and economic characters of NC55 in cured tobacco leaves were much better thanZhongyan 100.
