摘　　要：为明确不同生态区域烤烟中Amadori化合物含量(质量分数)差异,选取8个不同香型风格烤烟生态区249份烟叶样品,分析了不同生态区域Amadori化合物含量及其相关性,以及与化学品质指标间的关系。结果表明:①8个香型风格烤烟生态区不同部位烟叶Amadori化合物总量整体表现为:上部叶>中部叶>下部叶,基本服从正态分布,其中Fru-Pro含量最高。②烤烟Amadori化合物之间多数表现为正相关。③基于热图分析不同生态区域烤烟Amadori化合物含量整体表现为Ⅷ区>Ⅵ区>Ⅴ区>Ⅰ区>Ⅱ区>Ⅲ区>Ⅳ区>Ⅶ区。西南高原生态区-清甜香型(Ⅰ区)Fru-Pro、Fru-Gln和Fru-His含量较高。其中Fru-Pro与氮碱比呈显著负相关;Fru-Phe、Fru-Ser、Fru-Val、Fru-Thr和Fru-Leu与钾氯比呈极显著负相关;Fru-Tyr、Fru-Ile和Fru-Aba与钾氯比呈显著负相关。In order to measure the contents(mass fraction)of Amadori compounds in flue-cured tobacco leaves from various ecoregions,249 tobacco leaf samples from 8 flue-cured tobacco ecoregions with different flavor types were selected and their contents of Amadori compounds in leaves were analyzed.Correlations of the Amadori compounds with chemical quality indexes from different ecological regions were determined.The results showed that:1)The contents of total Amadori compounds in leaves from different stalk positions in the 8 ecoregions were in the order of upper leaves>middle leaves>lower leaves,all of which were normally distributed,and the content of Fru-Pro was the highest.2)Most Amadori compounds in the flue-cured tobacco were positively correlated with leaf sensory properties.3)According to heat map analyses,the 8 ecoregions in the order of the contents of Amadori compounds were RegionⅧ>RegionⅥ>RegionⅤ>RegionⅠ>RegionⅡ>RegionⅢ>RegionⅣ>RegionⅦ.The contents of Fru-Pro,Fru-Gln and Fru-His in the leaves from southwest plateau ecoregion-fresh sweet flavor type(RegionⅠ)were higher.Among them,Fru-Pro content significantly negatively correlated with nitrogen/nicotine ratio;the contents of Fru-Phe,Fru-Ser,Fru-Val,Fru-Thr and Fru-Leu extremely significantly negatively correlated and the contents of Fru-Tyr,Fru-Ile and Fru-Aba significantly negatively correlated with potassium/chlorine ratio.
