The air is moist if VPD (Vapour Pressure Deficit) is high.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
Respiration is a cellular process to obtain chemical energy from
the oxidation of plant tissues.
the oxidation of water.
the oxidation of organic molecules.
the oxidation soil nutrients.
Då VPD ökar blir assimilationen långsammare eftersom växten tillsluter sina klyvöppningar.

High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Since stomata are the same pores through which carbon dioxide enters into the leaves, the result of their closure is a reduction in photosynthesis.
REW stands for "Relative Extractable Water"
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
Photosynthesis shuts down if the temperature of previous night has been lower than
The stage of acclimation at any given day depends on the temperatures experienced by the plant during the previous months.
The stage of acclimation at any given day depends on the temperatures experienced by the plant during the previous days.
As VPD increases, photosynthesis decreases due to the closure of the stomata.
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.
Photoinhibition means the decrease in photosynthesis due to
exposure to shortage of soil moisture.
exposure to excess of CO2.
exposure to high temperature.
exposure to excess of light.
In trees, approximately half of the carbon bound in photosynthesis is used for construction of new biomass.
