Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Almost half of the total biomass of a tree may be allocated to the roots.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
In some part of the stems, some photosynthesis may also occur.
What is the source of carbon that is assimilated in photosynthesis?
The rate of respiration decreases with temperature.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
soil moisture (REW).
photosynthetically active solar radiation (PAR).
air temperature (T).
air humidity (VPD).
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
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.
Transpiration decreases as air becomes drier.
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.
