• Label: Leaf stomatal conductance to water vapour per unit leaf area during Asat measurement (gsw)
• Entity URI: https://w3id.org/APD/traits/trait_0020612
• Type: numeric
• Definition: The stomatal conductance [EnvThes:21211] to water vapour 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 ambient atmospheric carbon dioxide [ENVO:01000451] concentrations [PATO:0000033], recorded per unit leaf area [PATO:0001323]. Stomatal conductance is the rate [PATO:0000161] of gaseous [MESH:D005740] water [CHEBI:15377] diffusion [NCIT:C82333] through stomata [PO:0008032].;The rate of gaseous water diffusion through stomata in a leaf exposed to saturating light (photosynthetically active radiation) levels and ambient carbon dioxide concentrations, recorded per unit leaf area.
• Additional comments: Stomatal conductance refers to both the rate of water vapour diffusion exiting the leaf and carbon dioxide diffusion entering the leaf, but is reported here as the rate of water exiting the leaf.
• units: mmol{H2O}/m2/s
• allowable range: 0.1 - 2000 mmol{H2O}/m2/s
