WebWater potential values for water contained within a plant’s root, stem, or leaf are therefore stated in terms of Ψwpure H2O. In plant solutions, the water potential is controlled by solute content, pressure, gravity, and matrix influences. The following equation can be used to decompose the potential of water into its constituents: WebWhen P > 0 MPa, the osmotic potential, π = Ψ – P (MPa), i.e. the negative value of the distance between the lines for P and Ψ. When RWC < 0.912 (i.e. less than point of turgor loss), π ≈ Ψ. The slope α is a measure of the elasticity of the cell walls. [Source: Vos and Oyarzún (1988).]
