• Label: Leaf ambient quantum yield
• Entity URI: https://w3id.org/APD/traits/trait_0020418
• Type: numeric
• Definition: Ambient quantum yield [TO:0012004] of photosystem II [GO:0009539], as determined through chlorophyll fluorescence [GO:0090546]. Quantum yield is the ratio [PATO:0001470] of photons [NCIT:C88112] absorbed to photons emitted [SIO:000384] through fluorescence.;A trait that indicates the health of photosystem II in a light adapted leaf. Quantum yield is calculated as the ratio of (maximum fluorescence under ambient conditions)-(fluorescence under ambient conditions)/(maximum fluorescence under ambient conditions).
• Additional comments: None
• units: {dimensionless}
• allowable range: 0.01 - 1 {dimensionless}
