The purpose of this study was to evaluate the effect of temporary pH reductions on tuberization of ¡®Dejima¡¯potato in aeroponics. The pH and EC of nutrient solution were adjusted to 6.0¡­6.5 and 1.2mS/cm, respectively. On 35th day after planting, plants were subjected to pH 3.0, 4.0, 5.0 and 6.5 for 10hrs. After 5 days mini-tuberization was shown in pH 3.0 treatment and was significantly increased up to 20 days. Temporary low pH treatment resulted in the increase of stolen formation and of tuber dry weight. Number of mini-tubers per plant on 90th-day after planting was 72.1, 69.8, 65.2, and 60.3 in pH 3.0, 4.0, 5.0 and 6.5 respectively.
