Waterpotential is caused by osmosis, gravity,mechanicalpressure, ormatrixeffects includingsurface tension. It is useful in understandingwatermovements withinplants,animals, andsoil. Word origin:potential » Late Latinpotentiālis, powerful, from Latinpotentia, power. Compare:Osmotic Potential. See also:o...
In Figure 2, water will move from a region of higher to lower water potential until equilibrium is reached. Solutes (Ψs), pressure (Ψp), and gravity (Ψg) influence total water potential for each side of the tube (Ψtotalright or left), and therefore, the difference between Ψtotalon...

where Ψs, Ψp, Ψg, and Ψmrefer to the solute, pressure, gravity, and matric potentials, respectively. “System” can refer to the water potential of the soil water (Ψsoil), root water (Ψroot), stem water (Ψstem), leaf water (Ψleaf) or the water in the atmosphere (Ψatmosp...

The effects of water stress and nitrogen availability on leaf water potential, nitrogenase activity, and growth was studied in a pot experiment with Leucaena leucocephala seedlings, Water stress was imposed on fertilized and unfertilized plants after inoculation with Rhizobium. Non-inoculated seedlings we...
Here we show that cutting the sapwood of mature, 35 m tall trees in half hardly affects crown water status and transpiration. Counter expectation, this first adult tree sapwood interception experiment revealed that shoot water potential in the canopy (assessed by using a 45 m canopy crane...
