Alternate method of onion storage without the application of a growth regulator

Abstract

The effect of relative humidity on keeping quality of onions (Allium cepa cv. Downing Yellow Globe) was investigated as an alternative to the application of growth inhibitor, maleic hydrazide. Eleven months after storage at 40% or lower relative humidity and 3±1 °C temperature about 70 to 81% of the onions remained in good marketing quality and 80 to 97% in good eating quality. Data presented show that a considerable potential exists for successful storage of onions without the use of maleic hydrazide.
