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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
As plants respire, they release
Plant respiration captures CO2.
Unlike photosynhesis, plant respiration captures atmospheric oxygen and releases carbon dioxide.
Transpiration decreases as air becomes drier.
Photosynthesis of a tree canopy is driven or influenced by
air temperature (T).
the total leaf area (LAI).
soil moisture (REW).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
In some part of the stems, some photosynthesis may also occur.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Carbon capture is performed by the green parts of plants via photosynthesis.
What is the source of carbon that is assimilated in photosynthesis?
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.
When there is low soil moisture, plants close its stomata pores which then decreases 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.
