Explore the data for this trait in the portal

• Label: Leaf internal CO2 concentration during Amax measurement (ci)
• Entity URI: https://w3id.org/APD/traits/trait_0020310
• Type: numeric
• Definition: The intercellular space [PO:0025379] carbon dioxide [CHEBI:16526] concentration [PATO:0000033] 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.;The CO2 concentration in intercellular (interstitial) spaces in a leaf exposed to saturating light (photosynthetically active radiation) levels and saturating carbon dioxide concentrations; ci.
• 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}/mol
• allowable range: 10 - 1800 umol{CO2}/mol
