Pressure-volume curves


In ecology, pressure-volume curves describe the relationship between total water potential and relative water content of living organisms. These values are widely used in research on plant-water relations, and provide valuable information on the turgor, osmotic and elastic properties of plant tissues.
According to the Boyle-v'ant Hoff Relation, the product of osmotic potential and volume of solution should be a constant for any given amount of osmotically active solutes in an ideal osmotic system.
= A constant
is osmotic potential and is volume of solution.
This can then be manipulated to a linear relation which describes the ideal situation:
= A constant
