In che modo la luce di lunghezza d'onda diversa influenza il diverso periodo di crescita su piante diverse?

　　Photoperiodic growth,germination,bloom and Flowering yield respond strongly to blue and red wavelength (PAR region).

　　Photosynthesis,flowering,climate response are all affected by the PAR light intensity,duration,distribution and light quality. Exactly influence list as below:

　　Blue-400~520nm

　　Blue light is best for Germination and seedling raising.Blue light’s photosynthesis effect is not so strong as red light.

　　Green light 520-610nm

　　Green light has better penetration,pass through plants deeply and increases overall photosynthesis. Green light is comfortable for human eyes,can decrease visual light pollution.

　　Red- 610~750nm

　　Red light is the main force of light and action,The best photosynthesis effect is achieve by red light work with certain blue light .Red light accelerating the growth of plant leaves and stems, controls photoperiod and flowering rhythm, affecting flowering and flower yield.
