Explore the data for this trait in the portal

• Label: Leaf photosynthetic nitrogen use efficiency during Amax measurement (PNUE)
• Entity URI: https://w3id.org/APD/traits/trait_0020710
• Type: numeric
• Definition: The ratio [PATO:0001470] of a leaf's [PO:0025034] photosynthetic rate [TO:0001015] to its nitrogen [CHEBI:25555] content, where photosynthesis is measured in plant leaves 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 [PATO:0000033].;The ratio of photosynthesis (CO2 assimilation rate) to leaf nitrogen content, where photosynthesis has been measured in a leaf exposed to saturating light (photosynthetically active radiation) levels and saturating carbon dioxide concentrations; PNUE.
• Additional comments: Leaf nitrogen content and photosynthetic rate can be record either per unit leaf area or per unit leaf mass, but both must have the same denominator.
• units: umol{CO2}/g{N}/s
• allowable range: 0.1 - 1000 umol{CO2}/g{N}/s
