• Label: Leaf photosynthesis rate per unit leaf area under saturating light and CO2 (Amax)
• Entity URI: https://w3id.org/APD/traits/trait_0020241
• Type: numeric
• Definition: The photosynthetic rate [TO:0001015] 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; CHEBI:16526] concentrations [PATO:0000033], recorded per unit leaf area [PATO:0001323].;The photosynthetic rate of a leaf exposed to saturating light (photosynthetically active radiation) levels and saturating carbon dioxide concentrations, at optimal leaf temperature and VPD conditions, per unit leaf area; maximum photosynthetic rate.
• Additional comments: Leaf temperature and leaf-to-air vapour pressure deficit should be recorded as context properties. If Tleaf and VPD are not reported, it is assumed measurements are made at typical temperature and VPD conditions for the plant.
• units: umol{CO2}/m2/s
• allowable range: 0.01 - 65 umol{CO2}/m2/s
