Abstract
With the best regression design of two factors,the experiment studied the relationship between leaf quality and constant temperature and time in the stem-dring stage of flue-cured tobacco.The result indicated that the content of petroleum ether extract,aroma and taste of cured-leaf presented a trend of parabola curve.As the increasing of temparature and time to a higher level in the range from 54.3 to 57.0 degrees and 12.5 to 16.7 hours the aroma and taste score was the highest.Under 54.3 to 57.0 degrees of temperature and 5 to 12.5 hours of the time the content of petroleum ether extract was the highest.The study also showed that it had a good relationship between the content of petroleum ether extract and aroma and taste.
