Sledování intenzity fotosyntézy u skleníkové kultury zeleniny
 Konvičná, Petra
The literary part of the work approaches the plant material, cucumbers (Cucumis sativus L.), the issue of greenhouse production and growing in hydroponics. A large part is devoted to describing the process of photosynthesis and the different factors affecting the impact and progress of the process. The practical part is devoted to monitoring and measuring the physiological characteristics of the photosynthetic apparatus using LCpro +: the intensity of photosynthesis, transpiration levels, water efficiency, stomatal conductance with cucumbers. Outside the parameters of photosynthesis is also evaluated chlorophyll content using the device CCM200plus Chlorophyll Content Meter and the ability of plants to use sunlight, thus fluorescence. Flourescence was measured with a fluorometer OS30p + Chlorophyll. Based on the evaluation, it was found that all measured characteristics were influenced by physiological and health status and degree of leaf damage.

Vliv mykorhizní symbiózy na zeleninovou sadbu
 Grégrová, Dana
The aim of this diploma thesis was to determine the impact of mycorrhizal fungi on the growth parameters of model vegetable crops. As a model crops were selected Cucumber (Cucumis sativus L.) and Tomato ( Lycopersicon esculetnum Mill.). There were selected these three sorts of arbusko - mycorrhizal fungi to inoculate the medium were the crop seeds were sown: genus Glomus. Glomus claroideum BEG210, Glomus intraradices BEG140 a Glomus mosseae BEG95. The experiment that was conducted on this diploma thesis took place partially in the glasshouse as well as in the climate chamber, both in Horticulture Faculty in Lednice, Mendel University in Brno. The evaluation of treatment impacts was focused on the growth parameters such plant size, the width of the root collar and the leaf area of plants. Besides these parameters was also compared the plants 'weight. The results were statistically analyzed using STATISTICA 12 and are also included in the thesis. From the results we can conclude that the positive effect of mycorrhiza was reflected in both plant size and the weight of above-ground parts, which means an increase in fresh biomass. For these parameters, there were statistically significant differences in compare to control variation. Mycorrhizal treatment had also a positive effect on the growth of leaf area, and thus the photosynthetic apparatus of plants was increased. These results were supported by statistically significant differences compared to the control, as well. So this means that the mycorrhizal treatment has a very positive effect on plants.
