The Variable Low Pressure Storage (V.L.P.S.) that regulates the different pressures P1 and P2 during storage in a chamber possesses advantages on the supply of O2 gas into the chamber and the exclusion of CO2 gas from it because of changing inner pressures periodically. Storage tests were done in order to compare V.L.P.S. with ordinary Low Pressure Storage, using cabbage and turnip. The pressure P1 was set up the 100mmHg, and the other presure P2 was set up the 300mmHg at these tests. V.L.P.S. was superior to the ordinary Low Pressure Storage in the ratio of weight loss or the appearance of both cabbage and turnip. The V.L.P.S. system did not require a moisture implement because the inlet air to the chamber was saturated instantly with water vapor which was produced by respiration or evaporation from cabbage or turnip.
