摘　　要：[目的]研究云南烤烟成熟度与常规化学成分之间的关系。[方法]选取C3F等级的成熟烟叶,根据GB2635-92烤烟分级标准,将烟叶成熟度进行档次划分。用连续流动分析仪分析烟叶样品的化学成分。[结果]云南烤烟成熟度与主要化学成分指标在样品间存在着广泛变异。成熟度与还原糖、含Cl量呈显著负相关,与盐碱、含K量呈显著正相关,与TN的相关关系不显著。[结论]当成熟度处于87%～90%时,各项化学指标均处于较为适宜的范围。[Objective] The relations between the maturity and routine chemical compound of flue-cured tobacco leaf was studied.[Method] The maturity degree of tobacco,selected beyond C3F level,was ranked according to GB2635-92 standards and the chemical composition in the tobacco sample was analyzed with the continuous flow analyzer.[Results] The results showed that there was the obvious difference between the maturity of tobacco leaf and routine chemical compound among varieties; negative relationship between the maturity of tobacco leaf and the content of reduced sugar,Cl; positive relationship between the maturity of tobacco leaf and the content of chlorine,K,respectively; and not correlation between the maturity of tobacco leaf and TN.[Conclusion] All of indexes of the flue-cured tobacco leaf were in reasonable range when its maturity was in 87%-90%.
