Farquhar photosynthesis model
WebThe photosynthesis model (Farquhar et al. 1980) defined a parameter J max, as the light saturated potential rate of electron transport. In practice, light saturation may not be achievable with a given light source, or the leaf may suffer damage if held under saturating light for a prolonged period, or measurement errors are greater at ... WebWe modified the widely used Farquhar, von Caemmerer and Berry photosynthesis model to include the carbon and electron requirements for nitrogen assimilation via the photorespiratory pathway. Our modified model improves predictions of photosynthetic CO 2 uptake and of rates of photosynthetic electron transport. The results highlight how ...

WebApr 1, 2004 · The calculation of photosynthesis is based on Farquhar et al.’s model (Farquhar, 1980) and is not analytical. For these reasons, in the KK‐model a simple analytic deduction of consequences (such as in eqn 1) is difficult. Possibly a combination of the two approaches is required. Other aspects are treated similarly in the T‐ and …
