Description

1. In the measurement of respiration rate of fruits and vegetables, it is doubtful whether the respiration rate would be of no connection with the surface area of the material, depending only upon the weight of it as expressed in a formula "CO_2 mg exhausted/1 Kg of sample/hr". Therefore, this experiments were performed to examine this question.
2. Employing tomatoes, cucumbers, green peppers, egg plants, mandarine oranges, pears and Japanese persimmons, materials which seemed to have the same characters were divided into groups, adjusting their weight to 1Kg correctly. And soon after the xperimental lots were coated with paraffin to regulate the respirable surface area, the respiration rate of the treated material was observed in comparison with of the untreated material.
3. As the result, it is evident that the respiration rate was affected by the weight of the materialnot by the surface area and demonstrating the above expression to be reasonable.
