Title: Influence of cured-tobacco variety, position and ecological factors on aroma components of tobacco leaf.
Abstract: Aroma components of tobacco leaf from different cured-tobacco varieties,positions and soil types,altitudes were analyzed in this paper.These 83 kinds compounds tested were classified into 6 types according to functional group.Using factor analysis and grey relational analysis,the influences of variety,position,soil type and altitude on these 6 types of aroma components were examined.The results showed that:(1) by aroma components testing,in 83 compounds,there were 73 compounds which made a large difference to leaf aroma,including 34 aldehydes and ketones,8 alcohols,7 esters,6 phenols,8 furans and 10 dicarboximides.(2)Content sequence of 6 aroma components in leaves was as follows:aldehydes and ketonesalcoholsestersphenolsfuransdicarboximides.(3)Sequences of total aroma components content were:for soil type,red earthyellow earthpurple soilbrown earthpaddy soil;for variety,HongDaYunyan87Yunyan85K326,for position,upper leafmiddle leaf.Aroma component contents of leaves whose altitudes were below 1600m were lower than those above 1600m.During 1600m to 2200m,the aroma component content also increased with the altitude increasing.
