... [Show full abstract] the practical use of this in-vitro plant. In this paper, the temperature was measured order to obtain the basic data for practical use of an in-vitro plant, and a cooling device using a peltier-device was manufactured to decrease a temperature around the plant. The temperature of the area around the plant can be locally decreased for a practical use of the plant.
