This study was conducted to determine the effects of electrolyzed acid and alkaline solutions on the growth and quality of radish (<I>Raphanus sativus</I> L.) sprouts. The fresh and dry weights of the radish sprouts, the contents per 100 g FW and amounts per leaf of chlorophyll, and the contents per 100 g FW and amounts per plant of sugar, ascorbic acid and 4-methylthio-3-butenyl isothiocyanate (MTB-ITC) were analysed. The plants cultivated in 1⁄1 and 1⁄2 strength alkaline solutions exhibited superior growth and a low MTB-ITC content. With an increasing degree of dilution of the alkaline solutions, the growth was retarded, and the contents of chlorophyll, sugar, ascorbic acid and MTB-ITC increased. The amounts of these components were the highest in the 1⁄2 strength alkaline solution. The plants withered and died in the 1⁄1, 1⁄2 and 1⁄5 strength acid solutions. The growth of the plants and the contents and amounts of above components in the 1⁄10, 1⁄50 and 1⁄100 strength acid solutions were similar to those of plants grown in distilled water. Cultivation in acid solutions did not improve the growth and quality of the plants.
