At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Carbon capture is performed by the green parts of plants via photosynthesis.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
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.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air temperature (T).
photosynthetically active solar radiation (PAR).
soil moisture (REW).
air humidity (VPD).
Transpiration decreases as air becomes drier.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.

In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
What is the source of carbon that is assimilated in photosynthesis?
In some part of the stems, some photosynthesis may also occur.
