The diploma thesis is focused on assessment of content of phenolic substances harvested in different parts of Hradec Králové. They were conservated at laboratory temperature, elevated (40řC, 60řC) and reduced (-18řC) temperature. Next part of thesis is focused on assessing of the content of anthocyanins in fruits, that had been conservated for 3 years in refrigerator. The theme was finding the best concept of postharvestal adjustment. Despite to the individual places of harvest, there were not mentionable differences found out in content of phenolic substances in fruits.
