1.280nm ~ 315nm influence on morphological and physiological processes is minimal.
2.315 nm ~ 420nm chlorophyll absorbs less impact photoperiod effect, prevent stem elongation. 3.420 nm ~ 500nm (blue) chlorophyll and carotenoids absorbed the largest proportion, the greatest impact on photosynthesis.
4.500 nm ~ 620nm dye absorption rate is not high.
5.620nm ~ 750nm (red) chlorophyll absorption rate "high", has a significant influence on photosynthesis and photoperiod effect.
6.750nm ~ 1000nm absorption rate, stimulate cell elongation, impact of flowering and seed germination.
