The fruit of sweet cherry are more
sensitive against external factors than many fruit species so
post harvest quality loss on sweet cherry is quite higher. For this reason, it is very
significant to reduce the post harvest losses and to extend the storage period in sweet cherry,
and this is one of the main objectives
for producers and consumers. The aim of the study was to determine the effects
of GA3, CaCl2 and modified atmosphere packaging (MAP)
applications on individual phenolics compounds in postharvest storage on sweet
cherry. In the study, GA3 was applied at 30 mg L-1 concentration
when fruit skin was yellow-straw, and CaCl2 was applied at 0.5% concentration
20 and 10 days before the estimated harvest date. The study consisted of 4
different spray (Control (water only), GA3, CaCl2, GA3+
CaCl2) and 2 packaging aplications (without and with MAP). MAP was applied to
the fruits after the harvest. In our study, individual phenolics such as
catechin, 4-hydroxybenzoic acid, epicatechin, caffeic acid, p-coumaric acid,
4-aminobenzoic acid and protocatechuic acid were determined. It has been
determined that pre-harvested GA3, and CaCl2 applications have increased the content of
individual phenolics in fruit. The concentration of individual phenolics
generally decreased with increasing cold storage time, whereas epicatechin and
4-hydroxybenzoic acid concentrations increased. 4-hydroxybenzoic acid and
caffeic acid concentrations were higher CaCl2, and GA3
treatments than in control in all measured period. The MAP application had a
positive effect on the losses of other phenolic compounds except catechin
during cold storage.
