Abstract
Report Summary: The role of bruising with respect to a watery scale condition of the hard, yellow, storage onion of the north central onion-growing area of the Midwest was explored. Artificially bruised onions showed a marked ability to "recover" from the visible effects of the injury. Such recovery was favored by room or 60° F. temperature over 38°. Bruised onions were not predisposed to decay as a result of bruising. Neither harvesting, storage, nor grading practices that were observed encouraged objectionable bruising symptoms. Researchers suspect damage occurs during transit. This defect has probably been confused on occasion with translucent scale resulting from long-term storage, or with freezing injury.
