Abstract

Abstract ‘Granex’ onions were stored in an air-conditioned room at 27°C, at 5° in air, 5% CO 2 −3% O 2 or 10% CO 2 −3% O 2 , and at 1° in air or 5% CO 2 −3% O 2 . Relative humidity of storages at 5° and 1° was maintained at 70% to 85%. The quantity of marketable bulbs decreased 12% to 25% per month when stored at room temperature. Virtually all onions were marketable after 7 months of storage at 1° in 5% CO 2 −3% O 2 . More than 92% of these bulbs remained in a marketable condition after an additional 3 weeks in air at room temperature. Bulb quality of these sweet onions decreased during storage, as indicated by lower sugar concentrations and greater pungency. Bulb quality decreased most rapidly when onions were stored in air at 1° and least rapidly when onions were stored in 5% CO 2 −3% O 2 at either 1° or 5°.
