Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
the total leaf area (LAI).
soil moisture (REW).
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to high temperature.
exposure to excess of CO2.
exposure to shortage of soil moisture.

Carbon capture is performed by the green parts of plants via photosynthesis.
In some part of the stems, some photosynthesis may also occur.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
What is the source of carbon that is assimilated in photosynthesis?
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
As plants respire, they release
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Leaf area increases with stand age, resulting in a decreasing rate of photosynthesis in the stand.
An increment in leaf area increases also the photosynthesis of a tree stand. However, the relationship is saturating.
