Various supporting materials (rockwool, perlite, vermiculite, and polyurethane) and nutrient supply cycles (12, 24, 36, and 48 h) were examined to determine the optimum condition for photoautotrophic micropropagation of potato (Solanum tuberosum L. cv. Dejima) plantlets in a nutrient-circulated micropropagation system. Compared to rockwool, perlite, and vermiculite, polyurethane with large air space in its porosity had low water retention power resulting in low water content. All the growth factors of in vitro potato plantlets grown on rockwool, perlite and vermiculite for 28 days were greater than those grown on polyurethane. The plantlets grown on rockwool had 8-fold higher dry weight than those grown on polyurethane. Optimum nutrient supply cycles of perlite, rockwool, and vermiculite were 12, 24, and 48 h, respectively. This result implied that the range of optimum nutrient supply cycle was influenced by water retention characteristics of supporting materials. This nutrient supply cycle in each supporting material was the condition to maintain the water content of 50% to 70% in the supporting material. The results on ex vitro growth and survival rate14 days after transplanting were similar to those on in vitro growth suggesting the importance of in vitro environmental control for plant mass production by micropropagation. Thus, supporting materials and nutrient supply cycles were crucial environmental factors to control water content of root-zone and the growth of potato plantlets in the nutrient-circulated photoautotrophic mass propagation system.
