AbstractIn order to cultivate plants under low pressure in closed environment, the germination rate of white radish was investigated under low pressure, low oxygen partial pressure and condition of pure oxygen. The result of these experiments showed that the germination rate was mainly affected by the oxygen partial pressure. This indicates that it is possible to germinate the seeds in lower pressure of pure oxygen. The germination rate of white radish was 75 percent at 6 kPa of pure oxygen. In the case of buckwheat, the germination rate was 73 percent at 6 kPa of pure oxygen at 20 C, and the germination rate at 20 C was higher than that at 25 C.
