Abstract

Fumigation of onion bulbs with Tetrachloroisophthalonitrile reduced weight loss by half of the control. The weight losses of the control onion bulbs stored at 80% RH were lower than those stored at 90% RH but no significantly different in case of fumigated onion bulbs. No rooting and sprouting to outside were detected during low temperature storage ($0^{\circ}C$) and $Q_{10}$ value of onion bulbs during storage was the range of 1.9-2.1. The weight losses of onion bulbs during storage were mainly due to decay rather than respiration, because there was positive correlation between weight loss and decay rate during storage period but not respiration ratio.
