Carbon becomes locked as part of the accumulating plant biomass as plants grow.
The effect of light on photosynthesis has a clear saturating pattern: more light results in more photosynthesis but eventually leaves cannot take full advantage of all the extra light.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to high temperature.
exposure to shortage of soil moisture.
exposure to excess of light.
The annual cycle of photosynthesis mainly follows
the changes in air temperature.
the changes in light.
the changes in soil temperature.
the changes in CO2 concentration.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
As plants respire, they release
Photosynthesis releases oxygen whereas respiration releases CO2.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
The rate of respiration decreases with temperature.
In some part of the stems, some photosynthesis may also occur.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air temperature (T).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
soil moisture (REW).
