Abstract
Abstract Preharvest sprays of aminoethoxyvinylglycine (AVG) drastically suppressed internal ethylene concentrations, and delayed or prevented ripening of ‘McIntosh’, ‘Spartan’, and ‘Spencer’ apples ( Malus domestica Borkh.) at room temperature (ca. 25°C) after harvest, the magnitude of delay varying with cultivar and with AVG concentration. However, after treated fruit had been stored with untreated fruit at 0°C, little or no difference in ripeness was discernible between treated and untreated samples. Internal ethylene concentrations in treated fruit after storage were much less than in controls but generally exceeded 1 ppm. Infiltration of ripe fruit with AVG severely suppressed ethylene production, but 2 minute dips in AVG solutions had no effect until after prolonged time in storage.
