The respiration rate of rough rice under unsteady atmospheric condition was measured by the pouch method. The effects of the change in gas concentration, temperature and moisture content on respiration rate and respiratory quotient were also examined. Respiration rates of rough rice were greatly repressed under conditions of increase in carbon dioxide concentration and decrease in oxygen concentration at high temperature of 20 and 30℃. Respiratory quotient was almost fixed at over 5.5% oxygen concentration without changing with the temperature. Anaerobic respiration was occurred at less than 5.5% oxygen concentration, in which respiratory quotient increased rapidly. At at mospheric condition, respiration rate of rough rice increased with rise in temperature; especially this increasing tendency was great at high moisture content. Respiratory quotient was also increased with rise in temperature.
