Analysis of Tobacco Leaf Quality Characteristics in Different Tobacco-growing Counties from Dehong Area
In order to explore the quality characteristics of tobacco leaves in different planting counties in Dehong and provide reference for the rational use of tobacco resources in Dehong,tobacco resources in 4 planting counties in Dehong,including Longchuan,Lianghe,Mangshi and Yingjiang,were collected to detect the appearance information of tobacco leaves,routine chemical components and aroma compounds,and investigate the quality characteristics of tobacco leaves in 4 planting counties in Dehong.The results showed that the mean values of R and G of tobacco leaves from Yingjiang were 112.83 and 79.64,respectively,which were significantly lower than those in the other three areas,and the color depth of tobacco leaves was also significantly deeper than those in the other three areas.The average reducing sugar content and nicotine content of tobacco leaves from Yingjiang area were 28.44％ and 2.55％,respectively,which were significantly higher than those in other three areas.The total amount of alcohols and ketones in Mangshi tobacco was higher,while the total amount of acids and esters in Yingjiang tobacco was higher.The results of cluster analysis based on routine chemical indexes and aroma compounds showed that there were obvious differences between tobacco leaves in Yingjiang area and those in other areas.
