Abstract:

In order to improve and optimize the bulk curing technology of feature variety ‘Minyan 35’, the effects of different curing measures on the qualities of upper and middle flue-cured leaves of ‘Minyan 35’ were investigated. The results showed that treatment A which applied with higher yellowing temperature and higher leaf drying moisture improved the apparent quality, economic characters, physical characteristics, chemical compounds harmony and smoking quality of flue-cured leaves of ‘Minyan 35’, as compared to the control which applied with lower yellowing temperature and lower leaf drying moisture. The flue-cured leaves quality of treatment B which applied with higher yellowing temperature and lower leaf drying moisture ranked only second to treatment A. As compared to treatment A, the leaf structure of treatment B was stiffer with larger proportion of blue veins and lower smoking quality. The flue-cured leaves quality of the control was the worst in the three treatments with lower apparent quality, economic characters, physical characteristics, chemical compounds harmony and smoking quality, as compared to treatment A and B.
