The Optimum Usage of Different Light Spectrum in Agriculture


Plants need a persistent energy source for growth and they receive it from light. Light influences on plants’ "physiological, morphological, and biochemical" properties with its three aspects "intensity, quality and length of radiation". Light is not the only source of photosynthesis but is the important and influential signal of the growth stages of plants from germination to flowering. Responses of plants to the light in the growth environment to the function of photosynthetic pigments are different from the function of other pigments in the presence of different light spectrums.
