By directing different intensities of blue or red light to plants, you can regulate their flowering process. Most scientists claim that red rays can speed it up, while blue or violet light slows it down.
Today, there are special LED luminaires capable of creating an optimal spectral composition and excellent light distribution.
The beneficial effect of phytochrome is the ability to control the process of flowering and germination of seeds, and the pigment does not affect different varieties of plants in the same way. For example, in short-day representatives of flora (these include some tropical, subtropical individuals), red light will inhibit flowering, but in long-day representatives growing in temperate climates, on the contrary, it will stimulate it. To achieve the opposite effect, grow the plant under the influence of far red light.
In order to equally stimulate the flowering of short-day and neutral plants, it is necessary to simultaneously influence them with rays of red and blue. It is possible to accelerate the flowering and fruiting of some plants by acting with rays of orange, green, yellow colors. Anthocyanins are responsible for the absorption of such light - dyes of different colors that are part of the cell sap. They just determine the final color of the fruits and flowers of plants.
