Súhrn: A series of physiological changes takes place in the postharvest blackberry (Rubus sp.) fruit. We investigated the effects of ferulic acid and natamycin on quality and antioxidant capacity in the fruit. The results showed that the nutrients consumption was delayed by their action. The skin and flesh of fruit had changed after treatments as seen by microstructural observation. The combined treatment group had smooth skins and clear flesh folds, while the other groups showed varying levels of disruption. The single and combined treatments increased the relative electrolyte leakage and the malondialdehyde content of the fruit. The content of reactive oxygen species increased with time, including the superoxide radical and hydrogen peroxide, this increase being the lowest in the combined treatment group. The combined treatment significantly increased the superoxide dismutase, catalase and peroxidase activities, and also reduced cell membrane damage, which causes the postharvest caducity of the blackberry fruit, thereby increasing its shelf life and maintaining its quality. This study provides a basis for improvement in postharvest storage of blackberry fruit.
