Abstract
Two lots of severely frost-damaged canola seeds (Brassica napus L. ’Regent’) were categorized according to damage type. Seeds from these lots ranged in gross morphology from normal appearance to severely shrivelled with reduced diameter and white patches over the surface. The white color of these patches was caused by accumulation of starch-like granules in the epidermal layers. Frost-damaged hulls showed a variety of symptoms resulting from arrested development. In addition to an accumulation of starch-like granules in the epidermis, frost-damaged hulls displayed abnormal secondary thickening in the palisade.Key words: Frost-damage, canola, seed development, hull structure
