A hydroponic culture system was developed for producing garlic and for determining ajoene concentration and compared with those of garlic plants grown in a soil culture system. Garlic plants were grown in the hydroponic culture and the soil culture in a growth chamber under an artificial lighting at photosynthetic photon flux density of 450 μmol m-2 s-1 during the 12-h photoperiod with white fluorescent lamps, air temperatures of 25/21℃ (light/dark), relative humidity of 75/90% (light/dark). Plants were grown on styrofoam boards and hanging in containers filled with nutrient solution in the hydroponic culture and on commercial soil filled in containers in the soil culture. Ajoene content in each plant part was determined after heated in rice oil. Average fresh weights of newly developed bulbs, roots and leaves in the hydroponic culture were 22.1, 65.8 and 36.5 g/plant, respectively, and was 3.5, 3.1 and 2.3 times, respectively, greater than those in the soil culture two months after planting. Ajoene contents in bulbs, roots and leaves in the hydroponic culture were 14.4, 11.6 and 7.8 mg/plant, respectively, and 4.1, 4.1 and 2.7 times, respectively higher than those in the soil culture. Garlic plants grown in the hydroponic culture were vigorous and healthy.
