Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to high temperature.
exposure to excess of CO2.
exposure to excess of light.
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.
Early spring is a tricky time for plants due to the combination of sunny but still quite cold days.
Almost half of the total biomass of a tree may be allocated to the roots.
Photosynthesis of a tree canopy is driven or influenced by
air humidity (VPD).
photosynthetically active solar radiation (PAR).
air temperature (T).
soil moisture (REW).
the total leaf area (LAI).
Carbon becomes locked as part of the accumulating plant biomass as plants grow.
The annual cycle of photosynthesis mainly follows
the changes in light.
the changes in soil temperature.
the changes in CO2 concentration.
the changes in air temperature.
De-hardening in spring involves gradual re-hydration of the cells, recovery of photosynthetic capacity and a tight control of water loss.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
At low air humidity, a plant closes its stomata to prevent transpiration. The action also decreases photosynthesis
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
A complex microbiota lives belowground, releasing carbon dioxide to the soil.
Carbon capture is performed by the green parts of plants via photosynthesis.
In general, the more carbon dioxide that is available to the plant, the faster the rate of photosynthesis - if other factors are favourable.
