摘　　要：为了弄清气候与土壤对烤烟香气前体物和香型风格的影响,采用不同烟区植烟土壤互换方法,在统一品种和栽培技术条件下,研究了相同土壤不同气候和相同气候不同土壤条件下烟叶的腺毛密度、腺毛分泌物、烷烃类、β-胡萝卜素和叶黄素等烟叶香气前体物含量以及香型风格之间的差异与变化。结果表明:在相同品种和栽培技术条件下,腺毛密度主要由品种的遗传基因决定,生态条件的影响较小;烟草腺毛分泌物、烷烃类、β-胡萝卜素和叶黄素4种烟叶香气前体物含量受气候的影响大于土壤,气候约占2/3,土壤约占1/3;烤烟香型风格主要取决于产地的气候条件,而土壤条件影响不明显。气候因素对烤烟香气前体物和香型风格的影响大于土壤因素,在气候因素中成熟期光照强度对烤烟香型风格和香气前体物含量影响最明显。For the sake of exploring the effects of climate and soil on leaf aroma precursors and style of flue-cured tobacco, By changing soils from different places, with the same variety and cultural practices, Leaf trichome density, trichome exudates, alkanes, β-crotene and lutein, leaf aroma style and precursors contents of tobacco leaves which were grown under the same and different climate conditions were studied. The results showed that leaf trichome density was mainly determined by genotypes of the variety and influenced less by climatic condition; Climatic factors had greater effect on the contents of leaf aroma precursors, such as trichome exudates, alkanes, β-crotene and lutein, than soil factors did,2/3 versus 1/3; Leaf aroma style was mainly affected by climate, soil effect was not considerable; Light intensity during leaf maturing period had most significant effect on leaf aroma style and precursors contents.
