Research Abstract	In order to develop a practical plant factory, it is necessary to establish the cultivation techniques for highly valuable plants. Objective of this study is the development of liquid culture techniques suitable for medicinal plants, categorized as the kinds of highly valuable plant. One problem for the liquid cultivation technique for medicinal plants is that, by the liquid cultivation, it is difficult to make root part grow as suitable form for material of Chinese herbal medicine, and root parts of medicinal plants are often used as the medicine materials. Therefore, three types of liquid supplying systems, which were able to control the amount of culture liquid optionally and did not prevent the respiration of root, were constructed and cultivation experiments were conducted. As a result, suggestion about suitable method of liquid supply for root-using medicinal plant might be obtained.
