Abstract
Studies related with the storage of peach fruits have great relevance in many fruit-growing countries, among which Egypt. The effects of pre-harvest sprays with calcium chloride and chitosan, separately and in combination, as well as post-harvest treatments with chitosan and ozone, on quality attributes, storability and marketability of {u2018}early swelling{u2019} peach fruits were studied throughout the 2014 and 2015 seasons. In pre-harvest experiment, peach trees were sprayed twice with 1% or 2% calcium chloride. The 1 {u036A} spraying was at pea stage, while the 2 {u036B} {u0369} one was performed 10 days before fruit harvesting. Chitosan sprays were performed at 0.5% or 1%, alone or in combination with 1% and 2% calcium chloride, 10 days before harvesting. Untreated trees served as control. As for post-harvest, chitosan was applied at concentrations of 0.5 and 1%, ozone at concentrations of 0.5 and 1 ppm. Fruits were harvested at maturity stage for both experiments, packed and stored at (0 {u00B0}C and 85-90 % RH) or at room temperature (25±2 {u00B0}C). A number of physical and chemical parameters were evaluated on stored fruits at equal intervals (7 days for fruits stored at 0 {u00B0}C for a total of 35 days, and 2 days for fruits stored at room temperature
