Abstract:
The swelling behavior of parenchymatous cell wall was studied in aqueous and non-aqueous solutions. The swelling was significantly linearly correlated with the static dielectric constant of the liquid. Increasing the dielectric constant above that of water (e.g. formamide) does not increase the swelling accordingly. In addition, the swelling is dependent on the type of the adsorbed ions, tending to decrease with the increased valency. The swelling in NaCl solution was higher than in CaCl2 solution at the same concentration. The swelling mechanism of the plant cell wall system is attributed to the attraction and repulsion forces acting in the diffuse double layer of the fibrillar surfaces, considering the limitation due to the fibrillar branching which forms interfibrillar connections. © 1991.
