Definition and determination of water saturation

Protoplasma Aims and scope Submit manuscript

Summary

Water saturation of a tissue can be expressed as a function of volume, osmotic potential, and modulus of elasticity of the tissue (E tissue).E tissue increases with increasing turgor pressure, which has been verified for a growing tissue. It is also known to depend upon the size of the tissue. Water saturation can be theoretically defined, but practically, can only be measured as a range of tissue volume within which changes in osmotic potential and turgor do not cause significant changes in volume. Some physiological consequences have been discussed.
