检测评价了河南省驻马店烟区60个C3F烟叶样品的理化指标与浓香型风格程度,并采用相关分析、逐步回归分析等方法研究了烟叶理化指标与浓香型风格程度的关系.结果表明:①烟叶厚度、钾、巨豆三烯酮A,巨豆三烯酮B,巨豆三烯酮C与浓香型风格程度显著正相关,挥发性碱、山奈酚糖苷、糠醛、糠醇、5-甲基糠醛、巨豆三烯酮D与浓香型风格程度极显著正相关,还原糖与浓香型风格程度显著负相关,芳樟醇、金合欢基丙酮、香叶基丙酮、β-紫罗兰酮、2-乙酰呋喃与浓香型风格程度极显著负相关；②糠醛、5-甲基糠醛、2-乙酰呋喃、香叶基丙酮与烟叶浓香型风格程度存在极显著回归关系,共同决定了烟叶浓香型风格程度变化的88.7％,是影响烟叶浓香型风格程度的主要指标.%Sixty C3F samples of flue-cured tobacco leaves were collected from Zhumadian to analyze the relationship between physical-chemical indexes and full flavor style degree of leaves with correlation analysis and stepwise regression analysis. The results showed that: 1) the full flavor style degree of leaves significantly positively correlated with leaf thickness, potassium, megastigmatrienone A, megastigmatrienone B, and megastigmatrienone C; extremely significantly positively correlated with volatile base, kaempferol-3-rutinoside, furfural, furfural alcohol, 5-methyl furfural, and megastigmatrienone D; while significantly negatively correlated with reducing sugar; extremely significantly negatively correlated with linalool, farnesylacetone, geranyl acetone, p-ionone, 2-acetyl furan; 2) there was an extremely significant regression relationship between full flavor style degree of leaves and furfural, 5-methyl furfural, 2-acetyl furan, geranyl acetone, which were the major components affecting the full flavor style degree of leaves, and determined about 88.7% of the changes of full flavor style degree of leaves.
