Abstract
The research was oriented on pre and postharvest conditions necessary for optimal keeping quality of perishable fruits: sweet cherries, strawberries and highbush blueberries. The influence of plant nutrients and preharvest calcium treatments on storability of fruits was evaluated. Analyses of quality parameters ( sugar and organic acid content, fruit firmness and ground colour) were performed during maturation in orchard and during storage period. The nondestructive chromametric measurements of fruit colour were compared with other quality parameters. All maturity parameters were used for the estimation of optimal picking date of fruits. The influence of storage temperature and modified atmosphere composition on postharvest metabolism and fruit storability was studied. Addition of acetaldehyde and ethanol in storage atmosphere on the postharvest physiology of fruits was investigated as well as their impact on fruit sensory quality.
