leaf_transpiration_per_area_at_Amax

Label: Leaf transpiration per unit leaf area during Amax measurement (E)
Entity URI: https://w3id.org/APD/traits/trait_0020661
Type: numeric
Definition: The transpiration [ENVO:02500035] rate [PATO:0000161] of plant leaves [PO:0025034] whose photosystem [GO:0009521] I and II reaction centers [GO:0009538; GO:0009539] are exposed to saturating [NCIT:C61427] photosynthetically active radiation [ENVO:01001864] and saturating 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 saturating light (photosynthetically active radiation) levels and saturating 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
