Solute potential (Ψs), also called osmotic potential, is negative in a plant cell and zero in distilled water. Typical values for cell cytoplasm are –0.5 to –1.0 MPa. Solutes reduce water potential (resulting in a negative Ψw) by consuming some of the potential energy available in the ...

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...

Highlight: Leaf water potential, osmotic potential, and soil moisture were measured in mixed grassland during the growing season following an October fire. Plant and soil water stress increased near the end of the May-August period in both burned and control sites. Potentials in nothern wheatgrass...
horticultural cropsWater (w) and osmotic (s) potentials were measured in leaves of irrigated and unirrigated Coxs Orange Pippin apple trees on MM. 104 rootstock during the summer seasons of 1969 and 1970. Turgor pressure potential () was assessed from the difference between and s....
Three methods for determining the relationship between xylem pressure potential as measured in a pressure chamber (an estimate of leaf water potential) and leaf relative water content were compared for apple leaves. A range of leaf water contents was obtained either by sampling leaves in the field...
C.Greatsurfacetension(大的表面张力)•andcohesion(内聚力）同类分子间具有的分子间引力叫做内聚力(cohesion)。由于水中存在大量的氢键，水的内聚力很大。液相与固相间的相互引力叫做粘附力(adhesion)。由于水是极性分子,它可以与其他极性物质形成氢键,因此水与极性物质间有较强的粘附力。如果水与某物质间的粘附力...
In hydration swelling, it is the chemical potential of water that is the most important driving force. Therefore, this paper focuses on the chemical potential of water, the influence of water chemical potential on pore water pressure, and the coupling between the water chemical potential and host...
