leaf_photosynthesis_Jmax_per_mass

Label: Leaf Jmax per unit leaf mass (Jmax)
Entity URI: https://w3id.org/APD/traits/trait_0020412
Type: numeric
Definition: Maximum [NCIT:C25564] electron transport [MESH:D004579] rate [PATO:0000161] through the photosynthetic [GO:0015979] electron transport chain [GO:0022900], recorded per unit leaf [PO:0025034] mass [PATO:0000125]. The value is a model parameter [STATO:0000034] derived from the portion of the photosynthesis A-ci response curve at high carbon dioxide concentrations where ATP and NADPH production by the light reactions [GO:0019684] limits the rate of carboxylation [MOP:0000591].;The maximum potential photosynthetic electron transport rate, recorded per unit leaf mass. This is a model-derived value, calculated from the portion of an A-ci response curve (curve showing the photosynthetic response to increasing carbon dioxide concentrations) at high carbon dioxide concentrations. This is the portion of the curve where the photosynthetic rate is limited by the rate of ATP and NADPH production by the light reactions.
Additional comments: Jmax values are very dependent on leaf temperature, so leaf temperature needs to be included as a context property.
units: umol{CO2}/g/s
allowable range: 0 - 3 umol{CO2}/g/s
