Flowering Date of Onion Bulbs as Affected by Light and Temperature Treatments during Storage1

Abstract

Onion ( Allium cepa L. ) bulbs exposed to light during all or a half of a 6-month storage period produced plants that flowered 2 to 4 days earlier than those kept in continuous dark. Bulb storage at 7°C resulted in earlier flowering than did a temperature regime of 2° the first half and 7°C the last half of the storage period.
