Abstract: The stress relaxation parameters To, Tm, b, and c vary depending upon the pre-extension rate when a cell wall specimen is stretched using a tensile tester. The effect of the pre-extension rate on the stress relaxation parameters of pea epidermal cell wall was investigated using a newly established equation. The change in the parameters due to the pre-extension rate can be corrected by the equation qualitatively and approximately quantitatively. The newly established equation appears to validly express the stress relaxation process with consideration for the pre-extension rate and the parameters Tok, Tmk, bk, ck and K in the equation seem to represent the characteristic mechanical properties of the cell wall, although the parameters To, Tm, b, and c are valid for practical use to analyze the auxin effect on the mechanical properties of the cell wall.
