Vítová, Jana ; Münzbergová, Zuzana (advisor) ; Dostálek, Tomáš (referee)
The aim of the bachelor's thesis is to present the possibilities, significance and possible problems of ex-situ protection for the future conservation of biodiversity of plants on Earth. In the introductory part of the thesis, the individual processes and programs of ex situ protection are described, with the help of literature search. At the same time, information on international cooperation in the field of seed banks and botanical gardens is presented, which, through their activities and mutual cooperation, create rescue programs to secure as many samples of plant material for possible future use. The work also mentions international plant databases, which provide the accurate and detailed information about the preserved material of rare and endangered plant species for the public. Further in the thesis, the currently known problems of ex situ protection with their impacts on the collected and stored material are mapped.
