abstract：BACKGROUND AND AIMS:Exogenous ethylene has recently gained commercial interest as a sprouting inhibitor of onion bulbs. The role of ethylene in dormancy and sprouting of onions, however, is not known. METHODS:A cultivar (Allium cepa 'Copra') with a true period of dormancy was used. Dormant and sprouting states of onio...
