    Comparison of chemical compounds in upper leaves of flue-cured tobacco among different countries

    Zhengzhou Tobacco Research Institute of CNTC, Zhengzhou, China
    By using 281 upper leaves samples of flue-cured tobacco harvested in 2016 from China, Zimbabwe, Zambia, Malawi and Tanzania as material, the contents of chemical compounds were compared among different countries. The results showed that: Significant ...
