The effect of LED blue light on plants

Blue light is a necessary complementary light for crop cultivation, which is necessary for the normal growth of crops.

Blue light inhibits stem elongation and promotes chlorophyll synthesis, which is beneficial for nitrogen assimilation and protein synthesis and is beneficial to the synthesis of antioxidant substances.

The blue ray affects the phototropism of plants, the appearance of light, the opening of stomata and the photosynthesis of leaves.

LED red light supplementation LED blue light can improve the quality of dry matter, subdivision and seed production of wheat, and increase the quality of dry matter of lettuce.

Blue light significantly inhibited the growth of leaf lettuce stems.

Increasing the blue light in white light can shorten the internode, narrow the leaf area, reduce the relative growth rate and improve the efficiency of N/C.

Higher plant chlorophyll synthesis and chloroplast formation and high chlorophyll a/b and lower chloroplasts require blue light.

Excessive blue light is bad for plant growth and development.

The combination of red and blue light can promote the growth and development of vegetable seedlings more than red or blue light monochromatic light. Different plants need different proportion of red and blue.300x300 LED panel lamp
