WebThe point where an increase in light intensity will not increase photosynthesis any more is called light saturation. In many crops, an upper leaf would be saturated at around 32,000 lux. However, because of shadowing of lower leaves, light levels of around 100,000 lux might be necessary for the whole plant to become light saturated. In a ... WebHere, we measured chlorophyll fluorescence and P700 redox state under fluctuating light conditions at 4 °C, 20 °C, and 35 °C in three mosses with different light requirements. Upon a sudden increase in light intensity, electron flow from photosystem II initially increased and then gradually decreased at 20 °C and 35 °C, indicating that the ...

WebFactors limiting photosynthesis. There are a number of factors which contribute towards the process of photosynthesis. The factor which is working at the lowest level will usually be the limiting factor of the process. There are several limiting factors which can reduce the rate of photosynthesis, eg temperature, light intensity and carbon dioxide concentration. WebApr 13, 2024 · Abstract.
