摘  要：
为揭示云南宣威烤烟清香型风格形成的化学成分基础,选择22个植烟乡(镇)上部叶代表样品158份,综合应用相关分析、多元方差分析,研究了主要化学指标与其清香型风格典型性的关系。结果表明,清香型风格典型性较高的宣威上部叶具有总糖、还原糖、淀粉含量及糖碱比、两糖差值较高,烟碱、总氮、挥发碱、莨菪亭、钙、氯、硫含量相对较低的特点,但上部叶清香型风格典型性随不同范围化学指标变化的趋势并非线性。清香型风格典型性相对较高的上部叶主要化学指标范围为:总糖27%～37%、还原糖21%～30%、淀粉4%～6%、两糖差2%～12%、总氮1.6%～2.0%、总植物碱2.2%～3.8%、挥发碱0.30%～0.45%、糖碱比8～12、莨菪亭0.05～0.09 mg/g、钙、氯、硫上限分别为3.2%、0.4%、0.6%。

摘  要：
In order to reveal the basic chemical constituents of the aroma type style of tobacco of Xuanwei,correlation analysis and multivariate analysis of variance were used to study the relationship between the major chemical indices and representativeness of flavor types of 158 representative samples of upper leaves of flue-cured tobacco from 22 villages and towns.The results show that the high representativeness of flavor types of tobacco leaves had the following characteristics,content of total sugar,reducing sugar,starch and the difference between the total sugar and reducing sugar,the ratio reducing sugar to nicotine were slightly high and content of nicotine,total nitrogen,total volatile alkali,scopoletin,calcium,chlorine,sulfur were slightly low.But the trend that the representativeness of upper leaves changed with the different value ranges of major chemical indices were not linear.The proper ranges of major chemical indices with higher representativeness of flavor type of upper leaves were ascertained: total sugar: 27%-37%,reducing sugar: 21%-30%,starch: 4%-6%,the difference between the total sugar and reducing sugar: 8%-12%,total nitrogen: 1.6%-2.0%,nicotine: 2.2%-3.8%,total alkali: 0.30%-0.45%,the ratio of reducing sugar to nicotine: 8-12,scopoletin: 0.05-0.15 mg/g,the upper limits of content of calcium: 3.2%,chlorine: 0.4%,and sulfur: 0.6%.
