摘要:

为明确影响湖北烤烟主栽品种‘云烟87'、‘K326'上部叶评吸质量的关键化学成分,测定湖北省2010—2020年‘云烟87'、‘K326'上部叶烟碱、总糖、还原糖、氯、糖碱比、氮碱比等关键化学成分,以及香气质、香气量、杂气、刺激性、余味等感官评吸指标,通过统计分析发现影响上部叶评吸质量的主要化学成分。方差分析结果显示,‘云烟87'、‘K326'品种间上部叶烟碱、总糖、还原糖、氯、糖碱比、氮碱比、钾氯比、评吸总分存在显著或极显著差异。简单相关分析结果显示,与评吸总分呈显著或极显著正相关的化学指标有总糖、还原糖、钾、糖碱比、钾氯比、两糖比,与评吸总分呈显著或极显著负相关的指标有烟碱、氯、总氮。逐步回归和通径分析结果显示,影响‘云烟87'上部叶评吸质量的关键化学指标是还原糖、钾、烟碱,影响‘K326'上部叶感官评吸质量的关键化学指标是钾、还原糖、氯。要提高湖北上部烟叶评吸质量,不同品种应区别对待,针对‘云烟87',生产上应着重提高还原糖含量,调控碳氮代谢,协同提钾控碱。针对‘K326',提钾是关键,同时适度提高还原糖和氯含量。

Abstract:

In order to determine the key chemical components affecting the smoking quality of the upper leaves of main flue-cured tobacco varieties ‘Yunyan 87' and ‘K326' in Hubei Province, the nicotine, total sugar, reducing sugar, chlorine, sugar-alkali ratio, nitrogen-alkali ratio and other key chemical components of the upper leaves of the two varieties from 2010 to 2020 were determined, as well as the sensory evaluation indicators, including aroma quality, aroma amount, odor, irritation and aftertaste. The main chemical components affecting the quality of upper leaves were detected under statistical analysis. The variance analysis results indicated the occurrence of significant to extremely significant differences between ‘Yunyan 87' and ‘K326' in nicotine, total sugar, reducing sugar, chlorine, sugar-alkali ratio, nitrogen-alkali ratio, potassium-chlorine ratio, and total smoking score of upper leaves. The simple correlation analysis results illustrated that the positive correlation regarding the total smoking score including total sugar, reducing sugar, potassium, sugar-alkali ratio, potassium-chlorine ratio, and two sugar ratio showed significant to extremely significant relations, the negative correlation regarding the total smoking score including nicotine, chlorine, and total nitrogen showed significant to extremely significant relations. The stepwise regression and path analysis results showed that the key chemical indicators affecting the smoking quality of the upper leaves of ‘Yunyan 87' were reducing sugar, potassium and nicotine, and the key chemical indicators affecting the sensory smoking quality of the upper leaves of ‘K326' were potassium, reducing sugar and chlorine. To improve the smoking quality of upper tobacco leaves in Hubei, different treatments should be applied to different varieties. For ‘Yunyan 87', the production should focus on increasing the reducing sugar, regulating carbon and nitrogen metabolism, and synergistically increasing potassium and controlling alkali. For ‘K326', the key is to increase potassium, and moderately raise the reducing sugar and chlorine contents.
