What is the difference between PAR and Biologically-Active Photon Flux?

Photosynthetically Active RadiationPhotosynthetically Active Radiation

In summary, while PAR specifically refers to the range of light wavelengths essential for photosynthesis (400-700 nm), biologically-active photon flux encompasses a wider range of wavelengths that can impact various biological processes. PAR is a subset of biologically-active photon flux, and the two terms are often used in the context of plant biology and horticulture to quantify and understand how light affects plant growth and development.
