This bachelor thesis deals with physiological disorders of grapevine. Its aim is to describe individual physiological disorders and suggested options of protection or correction of the resulting damages. In the introductory chapter, there is an explanation of the reasons why the protection of grapevine is so important. Next chapter is divided into two big parts. There are described symptoms of disorders and the possibilities of prevention or correction in both. The first one describes physiological disorders caused by deficiency or excess of nutrients. The nutrients listed here belongs to macroelements, microelements and useful elements. The second part describes disorders caused by adverse natural influences. Except weather influences such as frost, hail or sunlight, there are described damaging effect of herbicides or polluted environment. This thesis also contains the author's own commentary and a summary of findings in the conclusion.

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.
