Preliminary study about effects of low frequency sound on the growth andL-ascorbic acid contents in radish sprouts (Raphanus sativus L. var. longipinnatus L. H.Bailey) was done. Without any sounds, the sprouts grew well in the condition of 200 seeds ina plate. In the sprouts grown in the sound with 50Hz, the rates of germination, the rates ofthe sprouts growing over the length of 40mm, the means of wet weight, and the means of dryweight were higher than those of the sprouts without any sounds or with the sound with200Hz. The contents of L-ascorbic acid in the sprouts grown in the sound with 50Hz were alsohigher than those of the sprouts without any sounds. These results suggest that exposure tolow frequency sound with 50Hz could precipitate the germination, the growth, and the increaseof nutritional compositions in radish sprouts.
