leaf_photosynthesis_Jmax_over_Vcmax_25C

Label: Leaf Jmax to leaf Vcmax ratio at 25 deg C
Entity URI: https://w3id.org/APD/traits/trait_0020416
Type: numeric
Definition: The ratio [PATO:0001470] of a leaf's [PO:0025034] maximum [NCIT:C25564] electron transport [MESH:D004579] rate [PATO:0000161] to its maximum carboxylation [MOP:0000591] rate, reflecting the trade-off between photosynthetic gain and costs of excess energy dissipation, with the ratio affected by temperature, photosynthetically active radiation [ENVO:01001864] (light), and carbon dioxide [CHEBI:16526] concentration. These are both model parameters [STATO:0000034] derived from a photosynthesis [GO:0015979] A-ci response curve.;Ratio of photosynthetic electron transport capacity (Jmax) to maximum Rubisco activity (carboxylation capacity) (Vcmax). These are model-derived parameters, calculated from an A-ci response curve, reflecting, respectively the component of the curve where photosynthetic rates are limited by the light reactions versus low carbon dioxide concentrations.
