摘 要: | [目的]为进一步认识土壤温度与烟叶质量风格特色形成的关系提供数据支撑。[方法]在人工控制条件下,研究成熟期地温变化对烟叶色素、多酚和西柏烷类化合物含量的影响。[结果]双层遮阳降温处理使上部烟叶色素含量降低28.1%,西柏烷类化合物含量升高16.6%,使中部烟叶色素、多酚含量分别降低20.3%、27.9%;双层覆膜增温处理使上部烟叶多酚和西柏烷类化合物含量分别降低35.9%、47.9%,使中部烟叶色素和多酚含量分别降低27.1%、35.9%,西柏烷类化合物含量升高40.1%;单层遮阳处理和单层覆膜处理对烟叶上述3种致香物质的含量影响不显著。[结论]成熟期地温对烟叶致香物质含量有明显影响。

Abstract: | [ Objective] The aim was to provide data support for further understanding the relationship between soil temperature and the style characteristic of tobacco leaves. [ Method ] The effects of soil temperature on tobacco leaf pigments, polyphenol and cembranoids compounds at maturity stage were studied under the condition of artificial control. [ Result] Double-layer shading cooling treatment made pigment content in upper parts of leaves decrease 28.1% , and cembranoids compounds increase 16.6% , and made the contents of pigments and polyphenol in middle parts of leaves decrease 20.3% and 27.9% respectively; Warming with double-layer film mulching made the contents of polyphenol and cembranoids compounds in upper parts of leaves decrease 35.9% and 47.9% respectively, and made the contents of pigment and polyphenol in middle parts of leaves reduce 27.1% and 35.9% respectively, however, its cembranoids compounds content increased 40.1% ; Single-layer shading or single-layer film mulching treatment had no obvious effects on these three aroma components contents mentioned above. [ Conclusion] Soil temperature has significant effect on the content of aroma substance at tobacco maturity stage. |
