Description: Red Light: C hlorophyII absorption rate is low, has a significant effect on photosynthesis and photoperiod effect.For plant flowering and fruiting，Promote plant growth, germinatiion, flowering, results. The most dominant role during adding color on the plants, accelerate photosynthesis. 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. 7 . > 1000nm converted into calorie.
