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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Transpiration decreases as air becomes drier.
What is the source of carbon that is assimilated in photosynthesis?
In some part of the stems, some photosynthesis may also occur.
To transform atmospheric CO2 into organic molecules, plants can use the energy from
The rate of respiration decreases with temperature.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Carbon capture is performed by the green parts of plants via photosynthesis.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in soil temperature.
the changes in air temperature.
the changes in CO2 concentration.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
