Title

A Model of the Photosynthesizing Leaf

K. W. Brown Physiologia Plantarum 1969. doi:10.1111/j.1399-3054.1969.tb07416.x

Other claims from this paper (11)

Observation Calculated CO2 concentration at the point of photosynthesis at high light ranges from 32 to 144 μl/l depending on species.
Observation Calculated CO2 concentration at the point of photosynthesis decreased from the compensation point to a nearly constant value at high light.
Association Plants with higher photosynthetic rates had greater calculated CO2 concentration at the point of photosynthesis.
Association Calculated respiration rates of wheat leaves were twice as high as rates measured in the dark.
Association Light respiration rate may be twice as great as dark respiration rate in wheat leaves at the same temperature.
Observation Calculated values of K show variability within and between species.
Association The maximum N was independent of K in plants.
Association The relationship between K and maximum quantum efficiency was demonstrated in several species at constant CO2 levels.
Association Σr was inversely related to the maximum rate of photosynthesis across the species investigated.
Association Mesophyll resistance calculated for cotton was inversely related to CO2 concentration in air.
Mechanism CO2 transfer in cotton cells may involve a concentration-dependent chemical reaction in addition to or rather than physical diffusion.
