Blue Light: High Absorption by ChlorophyII and Carotenoids, Big Influence on Photosynthesis.For Plant Growth and Absorption. Can Enhance Chloroplast Activity, to Prevent Spindling Plant, But on the Other Hand, It Will Inhibition of Photosynthesis, So That the Plant Need Much Blue Light. Red Light: ChlorophyII Absorption Rate is Low, Has a Significant Effect on Photosynthesis and Photoperiod Effect.For Plant Flowering and FruitingPromote 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.
