摘　　要：盆栽试验条件下，以香料烟品种云香巴斯马1号为材料，研究了土壤水分对香料烟常规化学成分、香味物质及感官质量的影响。结果表明，随土壤水分含量的降低，香料烟总糖、还原糖和挥发碱含量下降，而烟碱和总氮含量以土壤水分55%±5%处理最高，40%±5%处理次之，70%±5%处理最低。随土壤水分含量下降，中部叶除新植二烯和乙酰吡咯外，各类香味物质含量以及香味物质总量均呈增加趋势；上部叶类胡萝卜素降解产物、苯丙氨酸降解产物的含量提高，但增幅小于中部叶。上部叶赖百当类物质和西柏烷类物质的含量随土壤水分含量降低而下降；上部叶有机酸3项指标和酯类物质含量以土壤水分为50%±5%处理最高。评吸结果表明，随土壤水分含量降低，中部叶香气质改善，香气量和浓度增加，杂气和刺激性减小，感官质量变好；上部叶感官质量以土壤水分含量为50%～60%处理最好。Pot experiments were conducted with oriental tobacco to investigate effects of soil moisture on chemical composition, flavor components and sensory quality. Results showed that content of total soluble sugar, reducing sugar and volatile alkali in leaves decreased with declined levels of soil moisture. Content of total nitrogen and nicotine in leaves was the highest when the level of soil moisture was at 55%±5%, followed by t40%±5%and 70%±5%. With the level of soil moisture declining, the content of all flavor components in cutters, except neophytadiene and acetyl pyrrole, increased, so was the content of organic acids, phenylalanine degradation products and carotenoid degradation products in upper leaves. However, the content of labdannums and cembranoids in upper leaves decreased with the level of soil moisture declining. Three indicators of organic acids and the content of esters in upper leaves were in the highest degree when soil moisture was at 50%± 5%. With the level of soil moisture declining, the quality of aroma improved with the volume and richness of aroma increasing and biting and undesirable taste decreasing, thus resulting in significant improvement of sensory quality. Sensory quality of upper leaf is best ensured at 50%-60%soil moisture level.
