• Label: Osmotic potential at full tugor
• Entity URI: https://w3id.org/APD/traits/trait_0021058
• Type: numeric
• Definition: A parameter [STATO:0000034] calculated from a pressure-volume curve [APD:glossary/40124], which is, for a shoot or leaf [PO:0025034], the osmotic potential (solute potential) when they are fully hydrated (relative water content = 100%). Osmotic potential is always negative and is the potential energy [ENVO:2000016] of water [CHEBI:15377] molecules to flow [NCIT:C41141] across a semi-permeable [PATO:0000982] membrane [GO:0016020] due to the differences in solute [SIO:010418] concentration [PATO:0000033] across the membrane.;A parameter calculated from a pressure-volume curve which is the osmotic potential (solute potential) in leaf cells at full turgor (when relative water content = 100%). Osmotic potential is the energy of water molecules to move across a semi-permeable membrane due to differences in solute concentration across a membrane and is least negative (largest) when plants are at full turgor.
• Additional comments: None
• units: MPa
• allowable range: -10 - -0.1 MPa
