Aleksandra Korićanac is a PhD student at the University of Belgrade, Faculty of Agriculture, and a Research Assistant at the Fruit Research Institute, Čačak, Serbia. Her research is largely focused on fruit quality changes during ripening, harvest, storage, and postharvest management of temperate zone fruit species, particularly plums. Little is currently known about how European plums (Prunus domestica) ripen. Harvest time is one of the main determinants of quality and storability of plums for fresh market consumption, but defining the ideal harvest time is only possible when the physical and biochemical changes during ripening are known. Furthermore, a significant variation in the ripening process between cultivars has been observed. The aim of this research was to evaluate the physical, chemical, and sensory properties during ripening of two European plum cultivars: the widely grown cultivar ‘Stanley’ and a new late-ripening cultivar ‘Petra’, released by the Fruit Research Institute, Čačak. Although similar patterns of change in some important quality parameters were observed in both cultivars (a decrease of fruit firmness and total acidity, an increase of soluble solids, total sugars, inverted sugars and sucrose), almost all examined physical attributes changed significantly between the two cultivars. Quality changes during ripening of ‘Stanley’ plum were marked and consequently fruit characteristics and suitability for fresh consumption differed significantly between harvests. On the other hand, the fruit quality of ‘Petra’ was more constant during the observed period, although the harvest window was much shorter.
