| Abstract: | Objective] To understand chemical components of flue-cured tobacco in Baihe of Shaanxi Province. Method] The chemical com- ponents of Baihe tobacco growing area in Shaauxi Province and its similarity with Zimbabwean flue-cured tobacco were analyzed. Result] The results showed that the average contents of nicotine, total nitrogen and the ratio of potassium to chloride in the samples were within suitable range, while those of the other chemical indies were slightly lower or higher. The mean value of chemical usability index of the samples was O. 61, which indicated that the overall quality of flue-cured tobacco chemical indicators was close to moderate level. Chemically the domestic samples and Zimbabwean flue-cured tobacco leaves of the same stalk positions was of moderate similarity, for different grades, the average simi- larity distance coefficients of B2F were the smallest. Conclusion] The study can provide theoretical basis for improving Baihe flue-cttred tobacco industrialization. |
