Cuticle composition and structure may be relevant factors affecting the storage potential of fruits, but very few studies have analyzed fruit cuticle composition from a postharvest perspective. In this work, the chemical composition of waxes and cutin (major cuticular components) was analyzed in cuticle samples isolated from"Celeste" and"Somerset" cherries (Prunus avium L.) after cold storage at 0 °C. Total cuticle amounts per surface unit (μg cm−2) increased along with cold storage. The triterpene ursolic acid, the alkane nonacosane, linoleic acid, and β-sitosterol were the most abundant components of cuticular waxes, whereas cutin composition was dominated by C18-type monomers. In spite of being comprised of similar chemical families, cultivar-related differences were found regarding the abundance and the evolution of some compound families during cold storage. To the best of our knowledge, this is the first report on changes in cuticle composition of sweet cherry during postharvest storage.
