In order to investigate quantitatively a complex effect of four variables, i. e., temperature t (-0.5〜+70℃), moisture content w (7〜29% WB), Iength of shreds L and stalk position p, on filling capacity (FC) of tobacco shreds, an experiment was carried out with two typical varieties in Japan, that is, Flue-cured V_1 and Domestic V_2 tobacco. Then the experimental data were analyzed y means of a statistical method. The important results obtained were as follows : (1) The complex effect of t, w, L, and p on (FC) can be represented by the following formula. (FC) =f(w) +f(w, t) +f(w, L) +f(p), where each function f on the right side of the formula is a quadratic function of variables shown in parentheses, for example w and t. (2) The degree of influence by variables on (FC) decreased in order of w<t≒p<L in the V_1, and in order of w<t≒L<p in the V_2. (3) In general, (FC) decreased as w or t increased, and (FC) showed a maximum value when L was a medium value. (4) Generally, (FC) of shreds cut from leaves on higher stalk positions was smaller than that of shreds cut from leaves on lower, and (FC) of V_2 was greater than that of V_1. (5) The variation of (FC) given in (1) to (4) corresponded well to the variation of elastic modulus of tobacco on the same condition.
