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.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
What is the source of carbon that is assimilated in photosynthesis?
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Plants open its stomata to avoid losing too much water.

As plants respire, they release
Carbon capture is performed by the green parts of plants via photosynthesis.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Transpiration decreases as air becomes drier.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Photosynthesis of a tree canopy is driven or influenced by
photosynthetically active solar radiation (PAR).
soil moisture (REW).
the total leaf area (LAI).
air humidity (VPD).
air temperature (T).
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
