摘要
为探究烤烟与白肋烟糖含量差异形成原因,以烤烟品种K326、中烟100和白肋烟品种达白1号、TN90为材料,研究了不同调制方式及施氮水平下烟叶糖含量的差异。结果表明,基因型对烤烟和白肋烟烟叶的水溶性总糖和还原糖含量影响最大,调制方式影响其次,施氮量影响相对较小。烤烟在晾制条件下水溶性总糖和还原糖含量较烘烤条件下明显下降,但仍处于较高水平;白肋烟在烘烤条件下水溶性总糖和还原糖含量较晾制条件下虽有所上升,但仍处于较低水平。中烟100中、上部烟叶还原糖与水溶性总糖比值均在0.95左右,且在不同调制方式间差异较小;而TN90中、上部烟叶还原糖与水溶性总糖比值在不同调制方式间差异较大,且均表现为烘烤>先晾再烤>晾制。
Field experiments with K326,Zhongyan 100,Dabai 1 and TN90 as materials were set up to ex-plore the reason for the differences of carbohydrate contents between flue-cured tobacco and burley tobac-co by investigating the changes of carbohydrate contents under the different conditions of nitrogen applica-tion rate and curing methods.Results showed that tobacco type had the most important influence on the contents of total sugars and reducing sugar,the second was curing methods,and the last was nitrogen ap-plication rate.The contents of total sugars and reducing sugar of K326 and Zhongyan 100 in air-curing condition showed a decreasing trend compared with flue-curing condition,but still at a higher level.Al-though the contents of total sugars and reducing sugar of burley tobacco in flue-curing had a certain rise, which was still at the low level.The ratios of reducing sugar and total sugars in both middle and upper leaves of Zhongyan 100 were approximately 0.95,and there was no significant difference among different curing methods.However, the significant difference was observed in both middle and upper leaves of TN90 among different curing methods in ratios of reducing sugar and total sugars, and the ratios were showed as flue-curing〉flue-curing after air-curing〉air-curing.
