摘要: 为研究湖南浓香型烟叶产区烤烟化学成分变化规律,于2011年和2012年采集烟叶样品111个,对不同年份、不同等级、不同品种进行比较分析。结果表明:2012年的总糖、还原糖、糖碱比以及钾氯比与2011年相比有所增长,2012年的总氮、烟碱、钾、氯、淀粉以及氮碱比与2011年相比有所下降。各化学成分指标在不同等级中差异显著或极显著,且2011年与2012年的等级变化规律基本一致。总糖、还原糖、钾、糖碱比、氮碱比、钾氯比变化为:X2F>C3F>B2F;总氮、烟碱、氯的变化为:B2F>C3F>X2F。同一化学成分在不同品种之间的变化规律不明显。

Abstract: A total of 111 samples in 2011 and 2012 was collected to study the variation of chemical constituents of various years, different grades and different cultivars of burnt\|sweetness type flue\|cured tobacco of Hunan. The results showed that the total sugar, reducing sugar, sugar\|alkali ratio and potassium\|chloride ratio of tobacco leaves in 2012 were higher compared with 2011. Total nitrogen nicotine, potassium, chloride, starch and nitrogen\|alkali ratio decreased. Differences in chemical constituents were significant or extremely significant among grades. Variation trend of 2011 and 2012 was basically the same. Total sugar, reducing sugar, potassium, sugar\|alkali ratio, nitrogen\|alkali ratio, potassium\|chloride ratio varied as follows: X2F>C3F>B2F;and total nitrogen, nicotine, chlorine showed as: B2F>C3F>X2F. The same chemical composition did not change significantly between different varieties.

Key words: flue\, cured tobacco, chemical constituents, burnt\, sweetness type
