The 10 pages that link to Photosynthetically active radiation, each with the reason it gives.

• Crop yieldRelated: Intercepting this light supplies much of the energy behind biomass production.

• CanopyRelated: Canopy leaves absorb and scatter much of this light before it reaches the understory.

• GreenhouseRelated: Greenhouse coverings must admit enough usable light for crop growth.

• PhotoprotectionRelated: Its useful energy can become hazardous when absorbed in excess.

• Impact winterRelated: Atmospheric darkness sharply reduces the light available for photosynthesis.

• IrradianceBroader topic: Its irradiance measures light available to drive photosynthesis.

• HouseplantRelated: Its intensity and duration determine whether a room provides enough usable light.

• Shade toleranceRelated: It defines the usable light whose scarcity creates shade.

• Vertical farmingRelated: Efficiently supplying this light is central to crop growth and electricity use indoors.

• Photic zoneRelated: This wavelength range supplies the light used to define the zone’s photosynthetic limit.
