Abstract
Volatile aroma components in leaves grown by applying 6 different proportions of combined application of organic fertilizer and chemical fertilizer were tested by GC/MS method to comprehensively improve aroma quality of leaves from all stalk positions in flue-cured tobacco.Results showed that application of 75% chemical fertilizer and 25% sesame seed cake fertilizer resulted the highest content of neophytadiene (1068μg·g-1) in lower position leaves,while application of 50% chemical fertilizer and 50% sesame seed cake fertilizer had the highest content of neophytadiene (1066 μg·g-1,971.5486 μg·g-1 respectively) in cutters and topper leaves.Application of 50% chemical fertilizer and 50% sesame seed cake fertilizer also resulted the greatest total carotenoid catabolites in all positions,especially the content of β-damascenon,farnesyl acetone,four isomers of megastignone,higher content of maillard reaction products and aromatic AA catabolites in three postions,and greater (35.1568 μg·g-1) total of cembratriendiol catabolites in topper leaves,lower total (31.7479 μg·g-1,20.5705 μg·g-1,respectively) in lower leaves and cutters.The application of 50% chemical fertilizer and 50% sesame seed cake fertilizer was more effective than 100% chemical fertilizer to increase content and harmony of aroma components,and hence improveing tobacco quality.
