Evaluation of biological seed treatment of different field crops
 TICHÁ, Eva
The thesis is focused on biological seed treatment of selected field crops using adhesive in combination with entomopathogenic fungi Metarhizium anisopaliae and mycoparasitic fungi Trichoderma virens. Guar gum, xanthan gum and carboxymethylcellulose were chosen as the adhesive. Within the experiments in laboratory conditions, the percentage of kernels germination of spring barley, winter oilseed rape and a cucumber was evaluated after 24 hours and energy of germination and vitality during 2 5 days. The adhesive in combination with the filamentous fungi had positive influence on growth and development of embryonic roots of spring barley and growth and development of seedlings in all tested crops. The evaluation of plant emergence took place under laboratory and field conditions and the plants were biologically treated. Furthermore, the ability to colonize environment of the entomopathogenic fungus M. anisopliae was verified in this thesis. The fungus was injected into the substrate using seed dressings. According to the results, the introduced fungus is able to infect larvae Tenebrio molitor and Galleria mellonella after specific time.
