贵州不同油分烟叶化学成分的差异

分析贵州省烟区8个县烤烟主栽品种K326不同油分烟叶中的烟碱、总糖等主要化学成分的含量及其协调性。结果表明，多油分烟叶比少油分烟叶的烟碱、总氮和蛋白质含量低，总糖和还原糖含量高，施木克值高，糖碱比较协调；氯离子含量较低，钾氯比较高，多油分烟叶具有更优的物质基础。

A study on the variation of chemical substances in flue-cured tobaccos different oil proportions

We have analysed the content and coordination of the main chemical substances such as nicotine, total sugar of the tobaccos with different oil states from the main cultivated tobacco variety K326 in eight counties of Guizhou province. The result shows as follows: For the carbohydrates and nitrogenous compounds, the contents of nicotine, total nitrogen and protein of the high oil tobacco are lower than those of low oil tobacco, but the contents of total sugar and reducing sugar of the high oil tobacco are higher than those of low oil tobacco, and their Shmuck value is higher, their sugar alkali proportion is more coordinated. It also shows that chloride ion content of the high oil tobacco is low, their potassium chloride content is relatively high. In conclusion, the high oil tobacco is of higher-quality material basis than the low oil tobacco.
