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...
Water potentialis a measure of the potential energy in water. Plant physiologists are not interested in the energy in any one particular aqueous system, but are very interested in water movement between two systems. In practical terms, therefore, water potential is the difference in potential energ...

In plant water relations research, predawn leaf water potential (Ψpd) is often used as a proxy for soil water potential (Ψsoil), without testing the underlying assumptions that nighttime transpiration is negligible and that enough time has passed for a
41b), where the decrease in bond strength each cycle could be attributed to the low chain mobility of the polymers during the brief (3 s) re-dissolution step and potential oxidation when the polymers were exposed to the air. Still, even after 4 cycles, adhered aluminum rods could still...
“Potential capillary water loss” is defined as a measure of the ability of the soil capillary gap to raise water from the groundwater to the earth surface, and they consider the depth of the water table as the most important factor affecting the magnitude of groundwater evapotranspiration. ...
The water potential refers to the ability of water in the system to perform physiological functions and depends on the hydrostatic pressure in particular tissues, cells, or cellular compartments (pressure potential); the amount of dissolved solutes (solute potential); interactions with solid surfaces ...
It has recently been found (Langmuir2003, 19, 6851-6856) that freshly distilled water takes a surprisingly long time to equilibrate with the atmosphere, that it undergoes large fluctuations in pH and redox potential, and that these effects are greater when the water is exposed to a magnetic fi...
