MR imaging of somatic embryos
Chovanec, Ján ; Kubásek, Radek (referee) ; Bartušek, Karel (advisor)
The aim of this bachelor thesis is measuring of tissue cultures of spruce MR imaging methods. Was measured set of samples, where was found contain of cluster in each cuts. To obtain the image, the magnetic resonance was used, specifically spin echo sequence. Method called spin echo is based on two pulses 90° and 180°. Selected method from the beginning of the work is than used to measure the diffusion and processing of cultures. In last part the work is devoted to data processing in Matlab and Marevisi.
Measurement of tissue embryos by MR imaging methods
Vrba, Jan ; Mikulka, Jan (referee) ; Bartušek, Karel (advisor)
The aim of this work is to determine the volume of water in tissue cultures of spruce MR imaging methods and changes during growth. Was measured set of samples, where was found contain of cluster in each cuts. It describes spin-echo method, which was used for measurement. In this work is given a description of the acquisition, calculation, evaluation and graphical representation of measured values.
Cultivation of grapevine in conditions in vitro
Faltus, Miloš ; Skala, Ondřej ; Bilavčík, Alois ; Zámečník, Jiří
Grapevine is a traditional crop in the Czech Republic, especially in the South Moravia region. It is a vegetatively propagated crop; hence vineyards are endangered by abiotic and biotic stress influence. The risk of plant damage due to frost and pest influence occurs in the field conditions according to season and locality. Cultivation of grapevine in conditions in vitro eliminates the risk. Higher utilization of the method is limited by sensitivity of some genotype to in vitro conditions. This methodology solves these problems and describes material introduction into in vitro conditions, explants multiplication and slow growth condition establishment. 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”.
