| 摘 要： | 对河南主产烟区37个烤烟样品的14项主要化学指标进行了分析.结果表明,①河南烤烟总糖、还原糖、总氮、烟碱、钾、氯、硫、有机钾、石油醚提取物总量、总灰分含量和氮碱比适宜,蛋白质含量和糖碱比略高,钾氯比稍低；②河南烤烟化学指标中糖碱比的变异系数(50.15％)最大,钾含量的变异系数(12.31％)最小；③烤烟总糖、还原糖、总氮、烟碱、蛋白质、总灰分、糖碱比在不同部位间差异显著；④烤烟钾、氯、有机钾含量、氮碱比和钾氯比在不同产区间差异显著；⑤烤烟总氮、烟碱、石油醚提取物总量、蛋白质、总灰分含量、糖碱比和氮碱比在不同颜色间差异显著. |

| Abstract: | 14 indexes of main chemical components from 37 samples were analyzed in flue-cured tobacco leaves from Henan tobacco-growing areas.The results indicated that:(i)The contents of total sugar,reducing sugar,total nitrogen,nicotine,potassium,chlorin,sulfur,organic potassium,total petroleum ether extract,total ash and the ratio of total nitrogen to nicotine in flue-cured tobacco leaves were medium,protein content and the ratio of total sugar to nicotine were high,and the ratio of potassium to chlorine was low.(ii)Coefficient of variation(50.15 %) of the ratio of total sugar to nicotine was the biggest,coefficient of variation(12.31 %) of potassium was the smallest.(iii)The contents of total sugar,reducing sugar,total nitrogen,nicotine,protein,total ash and the ratio of total sugar to nicotine in flue-cured tobacco leaves had significant difference among different positions.(iv)The contents of potassium,chlorin,organic potassium,the ratio of total nitrogen to nicotine and the ratio of potassium to chlorine in flue-cured tobacco leaves had significant difference among different tobacco-growing areas.(v)The contents of total nitrogen,nicotine,total petroleum ether extract,protein,total ash,the ratio of total sugar to nicotine and the ratio of total nitrogen to nicotine in flue-cured tobacco leaves had significant difference among different colours. |
