The effects of different spectrum on plants

390-405nm violet:

It is the central area of the phototaxis of plants, which can affect the morphology of plants, inhibits leggy growth, stimulate the anthocyanin of the plant, promote the color of the fruit/petal or leaf of the plant, and improve the quality.

450-460nm blue:

It has a great effect on the early stage of plant growth, helping plants to establish a developed root system. Blue light inhibits the growth of the trunk and pages of plants, but increases the robustness of the trunk. Chlorophyll a/b has a strong absorption rate in the blue region, which mainly helps plants to synthesize protein and amino acids.

515-525nm Green and 550-570nm Yellow-green:

Green light has a certain effect of promoting photosynthesis of plants. In a strong light environment (in conjunction with other light qualities), the effect of green light is greater. It can also penetrate the leaf canopy and increase the overall photosynthesis.

655-665nm red:

Deep red is the main force of photosynthesis.

It mainly helps plants produce carbohydrates, which makes plants grow taller and pages grow. In the low light environment, red light has the highest photosynthesis efficiency for plants.

730-740nm Infrared light:

Through infrared light irradiation, the photosensitizing pigment Pfr is converted to Pr, thereby inhibiting the flowering of plants and controlling the flowering cycle. Combined with 660nm, it can achieve dual-light gain benefit, which is much higher than the photosynthesis efficiency of 660nm alone.

Infrared light can make plants produce a shade effect. Under the irradiation of infrared light, plants feel that there is an object at a high place that blocks the light and inhibits their own growth. They will work hard to grow to a higher place, prompting the plant to grow taller quickly.
