对不同环境湿度条件下烤烘期间烟叶中主要含氮化合物代谢的研究表明,高湿变黄和高湿定色烤后烟叶总氮含量较低;湿度对烤后烟碱含量的影响不明显.低湿不利于蛋白质降解,高湿烘烤烤后烟叶蛋白质含量低于其他处理;氨基酸与之相反,以高湿烘烤烤后烟叶的含量较高.高湿的烘烤环境有利于硝酸还原酶保持活性,高湿变黄和高湿定色烤后NO-2含量较高,而湿度对NO-3含量影响不大.

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.
