Fajmon, Jiří
The bachelor thesis summarises the technological processes of forage harvesting for silage. The machinery, machinery lines for cutting, processing and forage conservation are the main topics of this thesis. The most important aim is to evaluate the possibilites of handling with forage and their suitability for use. The correct choice of machinery lines is essential for job efficiency and service's economy.

Silážování travních a jetelotravních porostů
Neuman, Aleš
This thesis describes several representatives of the most common types of Czech legumes and grasses, their ecological requirements and factors that affecting their cultivation. It assesses their benefits and suitability as individual components of clover-grass communities. It compares the cultivation methods and effectiveness for individual grass and clover-grass blends. It characterizes their feed value, assesses the factors affecting the quality of the resulting forages as well as the factors affecting the suitability of these forages for preservation as silage. The importance of conservation is to preserve quality feed throughout the year. Conservation provides stable ration for production dairy cow in all seasons. Ensiling affects the final quality and nutritional value of feed, which is also highly dependent on the proper technological process. Silage additives has its undeniable contribution to the quality of the resulting feed, especially in the production of protein and half-protein wilted forage silage.

Grapevine cryoconservation
Faltus, Miloš ; Kotková, Renata ; Bilavčík, Alois ; Zámečník, Jiří
Storage of grapevine germplasm is endangered by biotic and abiotic stressors in the field conditions, and it is connected with the risk of valuable accession loss. Cryoconservation is a method which eliminates the risk and makes a safe long-term storage of plant germplasm possible. Cryoconservation method is based on storage of plant material at a temperature of liquid nitrogen when all processes are practically stopped but the viability of plant material remains. This methodology describes preparation of plant explants before cryoconservation, apical shoot tip dehydration by cryoprotectants, procedure and principles of long-time plant storage and plant recovery for evaluation of explant survival and regeneration. The Ministry of Agriculture of the Czech Republic is the user of this methodology and it will utilize it in the framework of “National Programme on Conservation and Utilization of Plant, Animal and Microbial Genetic Resources for Food and Agriculture”.

Substitution of beet sugar with plant Stevia rebaudiana and its effect on the sensory quality of selected products.
PEŠTA, Antonín
The main objective of this thesis was to substitute beet sugar with Stevia Rebaudiana Bertoni plant extract, and to assess effect of this substitution on sensory quality of selected products. Ten different samples of cherry jam were produced, using different combination of sweeteners in each of them. As sweeteners, beet sugar and Stevia leaf extract was used. This stevia leaf extract is even 400 times sweeter than common sugar. All samples of jam underwent sensory analysis and results have been graphically processed. The results has shown that Stevia has certain effect on sensory quality.
