Scholarcy highlights

  • Changes in the chemical composition of burley tobacco which take place in curing are being investigated at the Kentucky Agricultural Experiment Station in an attempt to understand the physiology of curing and its effect on leaf quality
  • A study was made of the changes in chlorophyll and carotene content of the leaves of stalk-cut burley tobacco during the air-curing process
  • The initial chlorophyll content of the leaves decreased with increasing maturity, and was higher in the upper than in the corresponding basal leaves
  • The rate of loss of chlorophyll in the top leaves was not greatly affected by maturity, and as a result, low chlorophyll concentrations were reached in a shorter time of curing in the overmature than in the immature plants
