Pot experiments were carried out for flue cured tobacco (Nicotiana tabatum L ) Results showed that there were effects of selenium and sulfur interaction on tobacco growth and leaf quality The effect on tobacco growth varied with soil type, growth stage, and Se, S rate Growth of earlier stage tabacco in red earth increased with the increase of Se at lower rates(4 94~6 18mg Se/kg) High rate of S(150 mg S/kg) enhanced biomass at lower rate of Se Application of Se decreased the growth of earlier stage tobacco in cinnamon soil and the decrease was depressed by S addition, indicating the antagonistic relation between Se and S However,the effect was different in the case of matured tobacco Biomass of matured bobacco was depressed by high rate S Contents of main chemical components (total sugar, protein, nicotine, and potssium)in tobacco leaves were influenced by both Se and S Application of moderate rate of SeO 3 2 and SO 4 2- (4 94 mg Se/kg with 75 mg S/kg) increased the contents of total sugar,nicotine and Se in tobacco leaves and decreased leaf protein content
