Vliv arbuskulárních mykorhizních hub na fyziologické projevy a plodnost u révy vinné (Vitis vinifera L.) =: The effect of arbuscular mycorrhizal fungi on physiological processes and fertility of grapevine (Vitis vinifera L.) /
 Sedláček, Martin
In a three-year field experiment we evaluated the effect of arbuscular mycorrhizal fungi (AMF) on physiological processes and fertility of grapevine (Vitis vinifera L.), there were two variants: inoculated with AMF compared to uninoculated control. The experiment took place at the Faculty of Horticulture, Mendel University in Brno, using Pinot noir and Lemberger planted as a field experiment and in containers (seedlings) and the second part took place in already established vineyard (mature plants). The positive effect of AMF on the must gained from mature plants of both varieties was observed at following parameters: sugar content, assimilable N, Mg and Fe. All the seedlings from both container and field experiment and both varieties demonstrated a positive effect of AMF on the intensity of photosynthesis, stomatal conductance and transpiration level. The expected positive impact of AMF on all investigated parameters was not significatntly demonstrated, which corresponds with the results of current research on this topic.

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.
