Abstract

Abstract Light had no significant effect on traits related to onion ( Allium cepa L.) seed production by plants from bulbs which had been exposed to various light and temperature treatments during storage. However, storage temperature affected seed yield/plant, number of seed/plant, number of seed/umbel, weight of individual seeds, and number of leaves/plant. Plants from bulbs stored at 7°C the first half and 2°C the last half of the storage period had the highest seed yield and the greatest number of seeds/plant. The heaviest seeds were produced by plants from bulbs that were stored at both 2° and 7° during the storage period. Bulbs stored at 2° and then at 7° produced plants that had fewer leaves than plants from bulbs stored at the 2 other temperature regimes.
