Almost half of the total biomass of a tree may be allocated to the roots.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
photosynthetically active solar radiation (PAR).
air temperature (T).
soil moisture (REW).
air humidity (VPD).
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
What is the source of carbon that is assimilated in photosynthesis?
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.
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 light.
exposure to high temperature.
exposure to excess of CO2.
exposure to shortage of soil moisture.
In some part of the stems, some photosynthesis may also occur.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Carbon capture is performed by the green parts of plants via 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
