| 摘 要： | 目的]为广东烤烟可用性评价提供科学依据。方法]采用紫外分光光度法和火焰光度法等方法测定广东不同生态烟区区域72份烤烟样品的主要化学成分,并与巴西烤烟的化学成分进行比较。结果]烟碱、总氮、还原糖、钾、氯含量分别为2.74±0.64%、1.80±0.22%、24.15±3.04%、2.28±0.34%、0.3±0.13%,糖碱比、氮碱比和钾氯比值分别为9.41±2.79%、0.69±0.17%和9.02±4.57%。氯含量和钾氯比在不同部位间差异不显著,其它指标在部位间的差异达到0.05显著水平。广东烤烟上部叶总氮、钾含量显著低于巴西烤烟,中、下部烟叶还原糖含量则显著高于巴西烤烟。韶关和梅州烤烟上部叶的综合得分分别为0.3和0.13,中部叶为0.45和0.32,下部叶为-0.31和-0.56。结论]广东烤烟的总氮、氯含量明显低于巴西烤烟,而其还原糖含量、糖碱比、钾氯比值明显高于巴西烤烟。

| Abstract: | Objective] The research aimed to provide scientific base for evaluating usability of flue-cured tobacco in Guandong province. Method] The main chemical components in 72 samples of flue-cured tobacco from different ecological tobacco- growing areas in Guandong were determined by ultraviolet spectrophotometry and flame photometry etc. and compared with that in Brazil flue-cured tobacco. Result] The contents of nicotine, total nitrogen, reducing sugar, potassium and chlorine were 2.74±0.64%, 1.80±0.22%, 24.15±3.04%, 2.28±0.34% and 0.3±0.13% resp. and the ratios of sugar to nicotine, total nitrogen to nicotine and potassium to chlorine were 9.41±2.79%,0.69±0.17% and 9.02±4.57% resp. The difference of chemical components of flue-cured tobacco leaves among stalk positions was significant at 5% level except chlorine content and the ratio of potassium to chlorine. Guangdong flue-cured tobacco was significantly lower than Brazil flue-cured tobacco on the contents of total nitrogen and potassium in upper leaves, but was significantly higher than Brazil flue-cured tobacco on the contents of reducing sugar in middle and lower leaves. In flue-cured tobacco from Shaoguan and Meizhou, the comprehensive scores of upper leaves were 0.3 and 0.13, that of the middle leaves were 0.45 and 0.32 and that of the lower leaf was -0.31and -0.56. Conclusion] Guangdong flue-cured tobacco was significantly lower than Brazil flue-cured tobacco on the contents of total nitrogen and potassium, but was significantly higher than Brazil flue-cured tobacco on reducing sugar content and the ratios of sugar to nicotine and potassium to chlorine. |
