Abstract

The effects of light spectral energy distribution of light emitting diode (LED) on growth and nutrition quality of radish sprouts have been investigated, with the dark treatment used as control. The results showed that light treatment dramatically inhibited hypocotyl elongation of radish sprouts, especially UV-B, as compared with dark treatment. Also, UV-B treatment significantly decreased the fresh shoot weight of radish sprouts. The soluble sugar content of‘Yanghua’radish sprouts was significantly increased under white light treatment, and significantly decreased under yellow light treatment. Whereas the soluble sugar content of ‘Qingtou’ radish sprouts was significantly decreased under yellow, blue and UV-B light treatments. The contents of soluble protein, free amino acid and vitamin C in‘Yanghua’radish sprouts were obviously increased under UV-B treatment. In addition, the blue light treatment dramatically increased the free amino acid content in‘Yanghua’radish sprouts, but not in‘Qingtou’radish sprouts. The vitamin C content of‘Qingtou’radish sprouts was obviously increased under UV-B treatment, but dramatically decreased under yellow light treatment. These results suggest that light treatments, especially UV-B, are effective in promoting nutritional quality of radish sprouts.
