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.
Eftersom koldioxid kommer in i växten genom klyvöppningarna går assimilationen långsammare då klyvöppningarna tillsluts.
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.
In trees, approximately half of the carbon bound in photosynthesis is used for construction of new biomass.
The air is moist if VPD (Vapour Pressure Deficit) is high.
"Stage of acclimation" refers to the seasonality of
the growth activity.
the litter fall activity.
the flowering activity.
the photosynthetic activity.
REW stands for "Relative Extractable Water"
Respiration is a cellular process to obtain chemical energy from
the oxidation of plant tissues.
the oxidation of water.
the oxidation soil nutrients.
the oxidation of organic molecules.
As VPD increases, photosynthesis decreases due to the closure of the stomata.
Då VPD ökar blir assimilationen långsammare eftersom växten tillsluter sina klyvöppningar.
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.
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.
Plants open its stomata to avoid losing too much water.
