摘要
对广东省主产烟区烤烟样品的糖含量、氮含量及其协调性进行了分析。结果表明,广东烤烟总糖、还原糖含量和施木克值较高,总氮、烟碱含量、糖碱比、氮碱比适宜,蛋白质含量较低,糖碱比的变异系数(32.28%)最大,蛋白质含量的变异系数(11.62%)最小。烤烟总糖、烟碱含量、糖碱比、氮碱比、施木克值在不同等级间差异极显著,还原糖含量在不同等级间差异显著。烤烟还原糖、总氮、蛋白质含量在不同地区间差异极显著。总氮含量在不同品种间差异极显著,还原糖含量在不同品种间差异显著。
Contents of sugar, nitrogen and the coordination were analyzed in flue-cured tobacco samples from Guangdong tobacco-growing areas. The results indicated that contents of total sugar, reducing sugar and Shmnck value were high, contents of total nitrogen, nicotine, the ratio of reducing sugar to nicotine and total nitrogen to nicotine were medium, content of protein was low, coefficient of variation（32.28 % ） of the ratio of reducing sugar to nicotine was the biggest, coefficient of variation（ 11.62 % ） of protein content was the smallest. Content of total sugar, nicotine, the ratio of reducing sugar to nicotine, total nitrogen to nicotine and Shmuck value in flue-cured tobacco leaves had highly significant difference among different grades, reducing sugar had significant difference among different grades. Contents of reducing sugar, total nitrogen and protein in flue-cured tobacco leaves had highly significant difference among different areas. Content of total nitrogen had highly significant difference among different cuhivars, content of reducing sugar had significant difference among different cuhivars.
