Carbon capture is performed by the green parts of plants via photosynthesis.
As plants respire, they release
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Transpiration decreases as air becomes drier.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in CO2 concentration.
the changes in air temperature.
the changes in soil temperature.
Almost half of the total biomass of a tree may be allocated to the roots.
In some part of the stems, some photosynthesis may also occur.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
air humidity (VPD).
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
soil moisture (REW).
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
