For the purpose of investigating the effects of addition of glycerol to tobacco laminae on three characteristics of shreds "Y" (fragility, filling capacity and equilibrium moisture content) , an ex-perimental plan was set up by using the glycerol addition "G" (O-6%) and the environmental humi-dity "h" (43-80%RH) as two main factors and the shreds length as a subsidiary factor. The tests were carried out with Flue-cured and Burley tobacco varieties. By means of statistical analysis of these experimental data, the relations among "Y", "G" and "h" were represented with experimental formulae . Moreover, the analysis of multiple regression for fragility and filling capacity was per-formed with two independent variables of real glycerol content "GR" and moisture content in tobacco shreds. The important results obtained were as follows: (1) When the "G" or the "GR" increased, the equilibrium moisture content of shreds increased, the filling capacity decreased and the fragility of shreds decreased. (2) The addition of glycerol to tobacco had a very large effect on the fragility of shreds, medium on the filling capacity and slight on the equilibrium moisture content. , (3) The "GR" in the shorter part obtained by sieving shreds appeared to be larger than that in longer one.
