When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Carbon capture is performed by the green parts of plants via photosynthesis.
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
air temperature (T).
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
In some part of the stems, some photosynthesis may also occur.
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.
Photoinhibition means the decrease in photosynthesis due to
exposure to high temperature.
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
What is the source of carbon that is assimilated in photosynthesis?
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Almost half of the total biomass of a tree may be allocated to the roots.
Plants open its stomata to avoid losing too much water.
