Résumé

Cold storage significantly stimulated ethylene forming capacity (EFC) in the peel, whereas the pulp of chilled fruit showed higher EFC as compared to unchilled fruit only after three months' storage. Endogenous abscisic acid (ABA) levels were significantly higher in the peel than in the pulp tissue. In the peel, chilling-induced ABA accumulation was observed during the first month. The possible roles of cold-induced ABA accumulation as a factor associated with high rates of ethylene biosynthesis after rewarming in 'Granny Smith' apples, and of endogenous ABA content as an indicator of storage potential, are discussed.
