Abstract: In order to study the effect of soil physico-chemical properties on megastigmatrienone content of flue-cured tobacco leaves and provide theoretical foundation for the selection of suitable tobacco-planting soil, the relationship between megastigmatrienone content in tobacco leaves and soil physico-chemical properties was analyzed by gray correlation analysis. The results showed that sand content and soil pH had the greatest influence on megastigmatrienone content, and the relationship between sand content in soil and megastigmatrienone content in flue- cured tobacco leaves accorded with quadratic. The relevancy of exchangeable calcium, exchangeable magnesium, available nitrogen, rapid available phosphorus and rapid available potassium with megastigmatrienone content was lesser.
