Physical and chemical changes during maturation of apple tree and in post-harvest changes play an important role. The aim was to focus on these changes and subsequently evaluated. In the literary part of the thesis is focused on chemical and nutritional aspects fruit ripening and respiration fruits, harvest, storage options and physiological disorders during storage. In the practical part were evaluated three varieties of apples "Rubinola, Prima and Topaz." First, the fruits were evaluated during ripening on the tree. For each variety were taken each five fruits every 7 days. The optimum ripeness was collected 40 varieties of each fruit and the cold storage for 90 days at a temperature of 3 °C. According to the qualitative characteristics of those properties (starch test, soluble solids and titratable acid) and mechanical-physical properties (penetrometer strength, weight) were measured varieties and subsequently evaluated.
