Résumé

Short-day onions (Allium cepa) grown under humid, subtropical conditions at two locations were evaluated in Florida, USA, for bulb size and yield at five harvesting dates (H1 to H5) ranging from 94 to 132 days after transplanting for 'Granex 33' and from 115 to 153 days after transplanting for 'Texas Grano 1015Y'. Both cultivars were transplanted in December. Maximum yields were attained by H4 for both cultivars and were attributed to increased bulb size rather than differences in plant (bulb) population. Nondried, large bulbs from each harvest were trimmed and stored at 1 or 10 °C and 80% RH for 2 weeks plus 2 weeks at 20 °C and 80% RH to simulate commercial storage and handling. Respiration rates, weight losses, sprouting and decay were measured. Results are detailed for both cultivars.
