• Label: Instantaneous water use efficiency (WUE)
• Entity URI: https://w3id.org/APD/traits/trait_0020762
• Type: numeric
• Definition: The ratio [PATO:0001470] of a leaf's [PO:0025034] photosynthetic rate [TO:0001015] to its transpiration [ENVO:02500035] rate [PATO:0000161], with photosynthetic rate and transpiration rate determined by gas exchange measurements.;The ratio of photosynthetic rate (A; CO2 assimilation rate) to transpiration rate (E; water loss), with photosynthetic rate and transpiration rate determined from gas exchange measurements, inside a leaf chamber. This is usually called instantaneous water use efficiency, but can also be referred to as photosynthetic water use efficiency (PWUE) or transpiration efficiency.
• Additional comments: None
• units: umol{CO2}/mmol{H2O}
• allowable range: 0.1 - 200 umol{CO2}/mmol{H2O}
