The hypobaric preservation of respiring plant matter without the step of humidifying the storage atmosphere by contacting it with a supplementary body of heated water is hereby disclosed, characterized by storage at controlled and correlated conditions of temperatures, subatmospheric pressure, evacuation rate, air recirculation rate and air intake rate, and by the dependence of each set of correlated conditions upon the weight, respiration rate and type of plant matter. Expanded relatively dry atmospheric air is passed into and humid rarified air is withdrawn from the storage chamber (16) at rates which maintain an optimal steady-state oxygen partial pressure for each type of respiring, oxygen-consuming plant matter (15), and a nearly saturated relative humidity sufficient to keep the temperature of the respiring, heat producing plant matter (15) equal to or slightly higher than the temperature of the chamber walls (16) and rarified air. |
