Carbon becomes locked as part of the accumulating plant biomass as plants grow.
The rate of respiration decreases with temperature.
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.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Carbon capture is performed by the green parts of plants via 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.
Almost half of the total biomass of a tree may be allocated to the roots.
As plants respire, they release
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in light.
the changes in air temperature.
the changes in soil temperature.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air humidity (VPD).
air temperature (T).
photosynthetically active solar radiation (PAR).
soil moisture (REW).
Photoinhibition means the decrease in photosynthesis due to
exposure to excess of light.
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to high temperature.

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.
What is the source of carbon that is assimilated in photosynthesis?
