Summary

Watery scales is a physiological disorder which develops in stored onion bulbs. Experiments were carried out to study gas exchange in onion bulbs to clarify whether changes in internal CO2 and O2 contents may result in watery scales. Onion bulbs (Jumbo and Laskala cultivars) were treated with the following methods in order to restrict gas exchange between the interior of the bulb and the external atmosphere: submerging the bulbs in water at 15 deg C for 0-8 days; injecting soyabean oil into the neck of the bulb prior to field curing or store drying for 1-4 weeks at 20 or 30 deg C; or covering the outer or centre parts of the bulb with vaseline. Results are given.
