The Influence of Curing Humility on the Nitrogen Metabolism in Tobacco Leaf

doi:10.3321/j.issn:1000-7091.2001.02.028

Abstract

Abstract: The study on the nitrogen metabolism in tobacco leaf under different temperature and humility condition during curing process indicated that the total nitrogen content in flue cured tobacco leaf was high under high temperature yellowing and high humility color fixing condition.The influence of curing temperature to the content of nicotine was not significant.The degradation of protein was hindered under low humility condition,but it was opposite under high humility condition,and so the protein content in tobacco leaf cured under high humility was lower than other treatments.Comparing to protein,the ammonia acid was on the contrary,and it's content was high in tobacco leaf cured under high humility.The high humility was propitious to nitrate reductase activity and the accumulation of nitrite.But the influence of the curing humility on the nitrate content was insignificant.
