High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Almost half of the total biomass of a tree may be allocated to the roots.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
Carbon capture is performed by the green parts of plants via photosynthesis.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
The rate of respiration decreases with temperature.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Transpiration decreases as air becomes drier.
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
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
In some part of the stems, some photosynthesis may also occur.
As plants respire, they release
