In some part of the stems, some photosynthesis may also occur.
The rate of respiration decreases with temperature.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon capture is performed by the green parts of plants via photosynthesis.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
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.
Almost half of the total biomass of a tree may be allocated to the roots.
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.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to excess of light.
exposure to high temperature.
What is the source of carbon that is assimilated in photosynthesis?
