Carbon capture is performed by the green parts of plants via photosynthesis.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Photosynthesis of a tree canopy is driven or influenced by
soil moisture (REW).
photosynthetically active solar radiation (PAR).
the total leaf area (LAI).
air humidity (VPD).
air temperature (T).
Almost half of the total biomass of a tree may be allocated to the roots.
What is the source of carbon that is assimilated in photosynthesis?
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
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.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
In some part of the stems, some photosynthesis may also occur.
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
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.
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of CO2.
exposure to shortage of soil moisture.
