The effect of conditions of storage on the respiration of apples. V. The relationship between temperature,rate of respiration,and composition of the internal atmosphere of the fruit

Change of rate of production of CO₂ leads to change in the composition of the internal atmosphere of apple fruits, and therefore the gross effect of temperature is a complex phenomenon which involves change in other parameters of the cellular environment.

An attempt has been made to determine the effect of temperature alone on the cellular rate of respiration, but it does not appear to be possible to do this for a bulky organ.

Over the range from 0° to 12 °C, the concentration of CO₂ in the intercellular spaces of an apple varied directly with the rate of production of CO₂, thus satisfying Fick’s law. Temperature appeared to have no effect on the porosity of the skin.
