Abstract: The mature harvest standard of enriched flavour flue-cured tobacco was determined by the test and evaluation of tobacco leaf appearance characteristics and chemical components of tobacco leaves of variety ‘Yueyan 98’, to explore the influence of intensive flue-curing condition on tobacco leaf quality in different harvest maturity periods. Results showed that the best harvested period of upper, middle and lower tobacco leaves in Shaoguan tobacco planting area was the optimum ripeness stage. Through bulk curing, the propotion of orange tobacco leaves increased. The appearance characteristics included brightness of colour and lustre, strong chromaticity and abundant oil content. As to the chemical components of upper, middle and lower taobacco leaves, the sugar alkali ratio and alkali nitrogen ratio were well coordinated. The leaves had sufficient and high quality amora, which manifested the characteristics of enriched flavor flue-cured tobacco.
