High soil moisture leads to decreased photosynthesis.
In boreal upland forests, low soil moisture decreases the rate of photosynthesis.
Låga växter, mikroberna i marken och markens funktioner i allmänhet drar under vintern nytta av.

Då VPD ökar blir assimilationen långsammare eftersom växten tillsluter sina klyvöppningar.

REW stands for "Relative Extractable Water"
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.
Since stomata are the same pores through which carbon dioxide enters into the leaves, the result of their closure is a reduction in photosynthesis.
When there is low soil moisture, plants close its stomata pores which then decreases photosynthesis.
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.
Plants open its stomata to avoid losing too much water.
Plant closes its stomata to avoid losing too much water.
As VPD increases, photosynthesis decreases due to the closure of the stomata.
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.
