不同密度和施氮量下烤烟化学成分与致香物质关系的研究
以云烟87为材料,通过相关分析、通径分析、逐步回归分析等方法,探讨了不同种植密度和施氮量下烤烟化学成分与致香物质的相互关系。结果表明：致香物质含量与氮碱比呈极显著正相关关系,与钾氯比呈显著或极显著负相关关系;烟碱、钾、氯、钾氯比对新植二烯含量的影响主要由直接作用引起,总氮对新植二烯的影响主要由间接作用决定,总糖、还原糖、糖碱比和氮碱比不仅直接作用强,而且还能辅助其他化学成分对新植二烯产生较大的间接作用。氮碱比、钾、总氮、还原糖对香气总量（除新植二烯）的影响主要取决于直接作用,烟碱和总糖对香气总量的影响主要取决于间接作用,糖碱比、钾氯比、氯对香气总量的影响是由直接作用和间接作用共同引起的。...

| Abstract_FL | Relationship of chemical components and aroma components of flue-cured tobacco in different planting density and nitrogen fertilizer application was investigated by correlation analysis, path analysis, regression analysis in two-factor split plot experiment with the material of Yunyan 87.The results showed that the aroma components existed extremely significant posi-tive correlation with the ratio of total nitrogen to nicotine, while there were significant or extremely significant negative correlation with the ratio of potassium to chlorine.The effects of nicotine, potassium, chlorine contents and the ratio of potassium to chlorine on neophytadiene proportion were mainly direct, while total nitrogen contents existed mainly indirect effects on neophytadiene pro-portion, the total sugar, reducing sugar contents, the ratios of reducing sugar to nicotine and the ratios of total nitrogen to nicotine not only existed intense influence on neophytadiene content, but also assisted the other chemical components to reinforce their in-direct influence.The ratios of total nitrogen to nicotine, total nitrogen, potassium, reducing sugar contents and aroma amount ( ex-cept neophytadiene content ) depended mainly on the direct impacts, while the impact on the nicotine and total sugar contents and aroma amount ( except neophytadiene content ) were mainly indirect.The ratios of reducing sugar to nicotine, the ratios of potassi-um to chlorine, chlorine content and aroma amount were affected by direct and indirect effects together. |
