Closed Transplant Production System at Chiba University
A closed system for transplant production was developed at the Matsudo campus of Chiba University, in order to study biological and engineering aspects of transplant production in closed systems and to test the feasibility of closed systems for production of transplants. In this system, virus-free transplants of sweetpotato (Ipomoea batatas (L.) Lam.) are vegetatively propagated and produced under sterilized conditions. Many new concepts and technologies are applied to this system to achieve the goal: to produce high-quality transplants at minimum usage of resources, and as scheduled. In the present paper, these concepts and technologies are introduced. A few examples of studies related to transplant production in closed systems using this facility are also described.
