Abstract
Abstract
Aminoethoxyvinylglycine (AVG) applied to apple trees (Malus domestica Borkh.) 1 week before harvest suppressed C2H4 production and delayed C2H4 peaks of fruit kept at room temperature. Early season cultivars (‘Early McIntosh’, ‘McIntosh’) were less affected by AVG than were late-season cultivars (‘Cortland’, ‘Royal Red Delicious’). While ripening was significantly delayed, maturation of ‘Puritan’ apples, as judged by changes in firmness, peel chlorophyll concentration, percent soluble solids, flesh starch concentration, and titratable acidity, was unaffected by AVG tree-sprays applied up to 6 weeks before harvest. Addition of C2H4 to the storage atmosphere accelerated ripening of AVG-treated fruit, whereas their ripening was slowed by storage at 0°C rather than at 3.3°.
