Light is one of the external factors of crucial importance for the plants growth and development in normal environmental conditions, as well as in the case of stress factors incidence. It is important not only the presence of light, because, the quality or the light spectra plays a major role throughout the all ontogenetic cycle of the plant. Therefore, especially in the current period, the use of light emitting diodes (LEDs) in indoor farming systems is one of the technological procedures applied in order to modify the light spectral composition, to regulate plants growth and last but not least to obtain value-added crops that are high in nutritional or nutraceutical contents. In view of the above, the purpose of this review is to present some of the newer results regarding the effects of blue light emitted by diodes (LEDs) on the physiological parameters of plants during vegetation period, which result in quantitative yield improvement, but also in terms of nutritional quality, including its preservation during the post-harvest period.
