- Label: Leaf Jmax per unit leaf area at 25 deg C (Jmax25)
- Entity URI: https://w3id.org/APD/traits/trait_0020411
- 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] area [PATO:0001323] and measured at 25 Celsius. 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, measured at 25 Celsius and recorded per unit leaf area. 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: This trait is explicitly for Jmax per leaf area measurements made at a temperature of 25 deg C. Measurements made at other temperatures should be mapped to `leaf_photosynthesis_Jmax_per_area`
- units: umol{CO2}/m2/s
