Abstract
Responses to pre- and post-harvest treatments have an impact on quality of fresh fruits and vegetables. Regulation of the nutritional system before harvest leading to an increase in calcium content of the fruit can create cell wall-support and protect against major post harvest rots e.g. gray mold caused by Botrytis cinerea. Meanwhile, post-harvest vacuum infiltration of apples and peaches in calcium salt-solution is effective against blue rot and brown rot caused by Penicillium expansum and Monilinia fructicola, respectively. Searching for safe products free of chemical residues led to the adoption of biological control of post harvest diseases for fruits and vegetables, utilizing a number of natural antagonists against post-harvest pathogens. The yeast, Candida oleophila was found to be effective antagonist against B. cinerea, Rhizopus stolonifer and Pencillium spp. when utilized on strawberries, apricot, citrus and apples. Pre-harvest chitosan spray affect post harvest infection by B.cinerea and quality of strawberries indicating a protective effect against deterioration of lower quality fruit. Moreover, it has a potential to prolong the storage life of strawberry and delayed ripening.
