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.
In some part of the stems, some photosynthesis may also occur.
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.
The annual cycle of photosynthesis mainly follows
the changes in CO2 concentration.
the changes in air temperature.
the changes in light.
the changes in soil temperature.
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.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
What is the source of carbon that is assimilated in photosynthesis?
To transform atmospheric CO2 into organic molecules, plants can use the energy from
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
soil moisture (REW).
the total leaf area (LAI).
air temperature (T).
photosynthetically active solar radiation (PAR).
air humidity (VPD).
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
The rate of respiration decreases with temperature.
