Effect of light wavelength on plant growth.
Optical wavelength (nm) The influence on the growth of plants
280–315 Minimal impact on morphological and physiological process
315–400 Chlorophyll absorbs less, photoperiod effect, tissue and stem elongation
400–520 Chlorophyll and carotenoid absorption proportion is the largest, the biggest influence on photosynthesis
520–610 The pigment absorption rate is not high
610–720 Chlorophyll absorption rate is low, have significant effects on photosynthesis and light cycle effect
720–1000 Absorption rate is low, stimulate cell extended, affecting flowering and seed germination
>1000 Convert into heat
