Analýza obsahu významných nutrientů v tropickém ovoci a v jejich škůdcích
Remencová, Julie
The diploma thesis is focused on analysis of selected elements of tropical fruits and their pests. The aim of the thesis was to find a relationship between mineral content of tropical fruits and their pests and to clarify whether the found correlations can be used for targeted pest management. The mediterranean fruit fly (Ceratitis capitata) and peach fruit fly (Bactrocera zonata) are one of the most dangerous and economically important species of Tephritidae family causing significant economical looses estimated in hundreds of millions of dollars per year. The theoretical part focuses on general description, production and consumption, chemical content and importance of individual analysed tropical fruit species. Literature review deals with selected elements – calcium, magnesium, iron, zinc, manganese and copper from the point of view of importance in human nutrition. The practical part describes analyses of the above mentioned elements using flame absorption spectrometry in samples of mango (Mangifera indica), mandarin (Citrus unshiu), kaki (Diospyros kaki) and pomegranate (Punica granatum) and samples of two fruit fly species C. capitata and B. zonata. From the correlations of elements contents in tropical fruits and their pests follows that the determination of calcium can be used for identification of the origin of the pest because a significant correlation was found only between the content of calcium in mandarin and C. capitata fed on mandarin.

Dovoz tropických plodin z Kolumbie do České Republiky: je poptávka dostatečně pokryta?
Přibylová, Jana ; Gutiérrez Chvalkovská, Jana (advisor) ; Zajíček, Miroslav (referee)
The demand for tropical fruit in the Czech Republic is rising, it´s a trend in the modern way of life. People in the Czech Republic, and all over the world, demand healthier ways of food consumption. We did research concerning a supply in the supermarkets and consumers. I found out, that a demand for tropical fruit was not very well covered and that people were demanding more variety of tropical fruit and were ready to up pay double prices for it. I compared data about consumption of tropical fruits in Germany, Austria and the Czech Republic. The comparison is drawn from net import of tropical fruit and net import it´s divided per capita. We proved that people in the Czech Republic were consuming fewer kilograms per capita per year than people in Germany and Austria. Annual consumption of tropical fruit in the Czech Republic grew by 7 % during the last five years, while in Germany it amounted to 0,3% and in Austria to 4,5%.
