| Abstract: | 【Objective】To clarify effects of different harvesting methods on tobacco browning in the upper leaves of flue-cured tobacco，to explore the appropriate harvesting methods，so as to provide theoretical guidance for improving the availability of upper leaves.【Method】The upper leaves of the normal harvesting treatment（CK），2 flue-cured leaves with stems（T1），4 flue-cured leaves with stems（T2）and 6 flue-cured leaves with stems（T3）were used as test materials.Effects of harvesting methods on lipid browning of upper leaves at the cell structural and gene molecular levels were explored using transmission electron microscopy，scanning electron microscopy and gene expression analysis techniques.And correlation between fatty acid content，cuticle thickness and lipoxygenase（LOX）activity of tobacco leaves was also analyzed.【Result】The order of browning rate of tobacco leaves in different treatments was: 6 flue-cured leaves with stems<4 flue-cured leaves with stems<2 flue-cured leaves with stems
