    Using changes in electrical conductivity and sucrose content of flue-cured tobacco leaves to assess ripeness more objectively

    NOLTE C.R.
    Tobacco and Cotton Research Institute, Rustenburg, South Africa
    No objective method to measure ripeness of flue-cured tobacco exists at this stage. Leaf ripeness is still assessed in a subjective manner according to leaf colour. Several factors, such as water logging, under fertilization and cultivar differences...
