In trees, approximately half of the carbon bound in photosynthesis is used for construction of new biomass.
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.
Då VPD ökar blir assimilationen långsammare eftersom växten tillsluter sina klyvöppningar.
Respiration is a cellular process to obtain chemical energy from
the oxidation of water.
the oxidation of organic molecules.
the oxidation of plant tissues.
the oxidation soil nutrients.
Since stomata are the same pores through which carbon dioxide enters into the leaves, the result of their closure is a reduction in photosynthesis.
Eftersom koldioxid kommer in i växten genom klyvöppningarna går assimilationen långsammare då klyvöppningarna tillsluts.
Photosynthesis shuts down if the temperature of previous night has been lower than
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.

REW stands for "Relative Extractable Water"
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
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.
High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
