Determination of volumetric elastic moduli of plant leaf cells based on pressure-volume curves

摘要

Volumetric elastic modulus(VEM) is an important parameter in biophysics and biomechanics of plants for in particular understanding cell growth.This paper proposes a new relation that can be used for precisely determining VEM.With the aid of this relation,it shows that the exponential approximation of the pressure-volume relationship adopted in most of the literatures in this field may lead to serious errors on VEM.
