• Label: Leaf transpiration per unit leaf area under ambient conditions (E)
• Entity URI: https://w3id.org/APD/traits/trait_0020660
• Type: numeric
• Definition: The transpiration [ENVO:02500035] rate [PATO:0000161] of plant leaves [PO:0025034] exposed to ambient [NCIT:C62306] photosynthetically active radiation [ENVO:01001864] levels and ambient atmospheric carbon dioxide [ENVO:01000451] concentrations [PATO:0000033], recorded per unit leaf area [PATO:0001323]. Transpiration rate is the rate at which plants lose water [CHEBI:15377] vapor [NCIT:C63390] through their stomata [PO:0008032].;The rate of water loss from a leaf exposed to ambient light (photosynthetically active radiation) levels and ambient carbon dioxide concentrations, recorded per unit leaf area.
• Additional comments: This trait assumes measurements were made on a leaf under changer conditions. Commercial gas exchange systems create wind inside the chamber to measure transpiration, which means transpiration inside chambers is not the same as transpiration with no chamber involved.
• units: mmol{H2O}/m2/s
• allowable range: 0.1 - 50 mmol{H2O}/m2/s
