In order to provide quality fruits throughout the year for the market, it is necessary to develop andimplement new and modern methods of storage. The investigations presented in this study had the aim to determinethe influence degree of “Phytomag” preparation on the processes of apple and plum fruits ripening in the post-harvest period. After treating the apple and plum fruits with “Phytomag” preparation and putting them in specializedboxes for 24 hours, they were stored in refrigerated chambers at the temperature of 10C and 85-90% relative airhumidity. Apple fruits were stored for 120 days, and the plums - 30 days. In order to determine the influence degreeof “Phytomag” preparation on the intensity of fruit ripening processes, the research was focused on the followingbiochemical and technological indices: the content of starch, carbohydrates, titratable acids, ascorbic acid (vit.C),flesh firmness and fruit shrinkage. The etylene synthesis inhibitor “Phytomag” significantly reduces the activity ofthe enzyme complex and, consequently, it slows down the biodegradation process of plastic substances involvedin the ripening processes of apple and plum fruits. At the moment of removal from storage, the investigated fruitswere characterized by a higher fruit pulp firmness, freshness, better aroma and flavor compared to the controlvariant, fact which enables us to conclude that, if necessary, their storage period could be extended.
