摘　　要：采用随机取样方法研究了延边地区烤烟化学成分与中性香气物质含量的关系。结果表明，还原糖和烟碱与各类香气物质总量相关性不显著；总氮与苯丙氨酸类、棕色化产物类、新植二烯含量及香气物质总量呈显著或极显著正相关，与苯丙氨酸类和棕色化产物呈显著二次曲线相关关系；蛋白质与除类西柏烷类以外的香气物质及总量呈显著或极显著正相关，与各类香气含量及总量呈显著或极显著二次曲线关系；钾与类胡萝卜类和类西柏烷类呈极显著正相关，且呈显著或极显著二次曲线相关关系；在总氮1．06％-1．99％、蛋白质3．45％-10．18％和钾O．66％-1．94％含量范围内，相对提高其含量，有利于烤烟香气物质含量的提高。The relationship between main chemical components and neutral aroma components in flue-cured tobacco were studied by the method of random sampling in Yanbian. The results revealed that reducing sugars and nicotine had no significant correlation with all kinds of aromatic matter; total nitrogen had significantly or high significantly positive correlation with phenylalanine, browing reaction, neophytadiene and total amount of aroma compounds, and existed significantly posil：ive quadratic correlation with phenylalanine, browing reaction contents. Protein had significantly or high significantly positive correlation with the others and total amount of aroma compounds except for cembratriendid, and had significant or high significant quadratic correlations with five groups on aroma components and total amount of aroma compounds. Potassium had high significantly positive correlation with carotenoid and cembratriendid, and assumed significant or very significant quadratic correlations. In the range of total nitrogen contents from 1.06% to 1.99%, protein contents from 3.45% to 10.18%, potassium contents from 0.66% to 1.94%, if increasing their contents, the content of aroma matters increased.
