Philips 2835ledWhat are the effects and roles of each frequency band on plant growth?

Philips 2835ledThe impact of 610-680NM red light on plant illumination:
1. Red light is the main force of photosynthesis, and under certain conditions, the effect of photosynthesis is the best
2. Under low light conditions, red light has the highest effect on photosynthesis in plants
3. Red light affects the control of photoperiod and flowering rhythm Pr/Pfr flowering period
4. Red light mainly helps plants produce carbohydrates, allowing them to grow taller and their leaves to grow.


The impact of 420-470NM blue light on plant lighting:
1. In low light environments, blue light has weak effects on plant photosynthesis
2. Blue light has a significant effect on the early growth stage of plants, helping them establish a well-developed root system
3. Blue light inhibits the growth of plant stems and leaves, but increases the thickness of the stems
4. Chlorophyll a/b has a strong absorption peak in the blue light region, mainly helping plants synthesize proteins and amino acids.
5. Appropriate blue light promotes uniform and healthy plant growth, improving the quality of plant production.


The impact of 520-570NM green light on plant illumination:
1. Green light has the effect of promoting plant photosynthesis
2. In strong light environments (in combination with other light qualities), the effect of green light is greater
3. Green light can penetrate the leaf canopy and increase overall photosynthesis
4. Green light can neutralize the red blue spectrum, reduce visual light pollution, and achieve good visual effects when light is mixed.

The effect of 360-420NM purple light on plant growth:
1. Purple light is the central region of plant phototaxis, which affects the construction of plant morphology
2. Purple light inhibits the growth of plant trunks and leaves (suppresses elongation)
3. Purple light stimulates plant anthocyanins, coloring plant fruits/petals or leaves and improving quality.


280-315NM: Has minimal impact on morphology and physiological processes.
315-400NM: Low chlorophyll absorption, affecting the photoperiod effect and preventing stem and leaf growth.
400-520NM (blue): Chlorophyll and carotenoids have the highest absorption rates and the greatest impact on photosynthesis.
520-610NM (green): Low pigment absorption rate.
610-720NM (red): Low chlorophyll absorption rate, significantly affecting photosynthesis and photoperiod effects.
720-1000NM: Low absorption rate, prolonged stimulation of cells, affecting flowering and seed germination. Greater than 1000M: converted into heat.
315NM has minimal impact on morphology and physiological processes. Chlorophyll absorption is low, which affects the photoperiod effect.
400NM - prevents stem elongation. The absorption ratio of chlorophyll (blue) to carotenoids is the highest, and it has the greatest impact on photosynthesis.
The absorption rate of 520NM pigment is not high, and the absorption rate of 610NM (red) chlorophyll is low, which has a significant impact on photosynthesis and photoperiod effects.
750NM - Low absorption rate, stimulates cell elongation, affects flowering and seed germination.
