As plants respire, they release
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of light.
exposure to excess of CO2.
exposure to high temperature.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Carbon capture is performed by the green parts of plants via photosynthesis.
In some part of the stems, some photosynthesis may also occur.
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.
The rate of respiration decreases with temperature.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Photosynthesis of a tree canopy is driven or influenced by
the total leaf area (LAI).
air humidity (VPD).
photosynthetically active solar radiation (PAR).
air temperature (T).
soil moisture (REW).
