Atractivity of buckwheat for bees
KOSCHANT, Jan
This diploma thesis ,,buckwheat attractivity for bees" deals mainly with native nectar plants for the processing of bees to honey. Work is folded in two parts. The theoretical part deals with the migration of colonies, both for nectar crops and plants with bee pollination needs. In ractical part of this thesis microscopic pollen analysis were performed and contents of pollen grains in honey from colonies, which were relocated to buckwheat growth was evaluated. Comparison of this honey with honey from the hives with similaar location, but without access to buckwheat growth was done.
Influence of genotype on rutin content in plants from genus \kur{(Fagopyrum)}
KRÁLOVÁ, Martina
The bachelor work is focused on evaluation of the influence of buckwheat species and variety on rutin containt in particular plant parts, on the total rutin yield per hectare production and on comparison varietal differences between both species, common buckwheat \kur{(Fagopyrum)}esculentum)} Moench) and tartary buckwheat \kur{(Fagopyrum tataricum)}. Rutin is a flavonol (quercetin-3-O- rutinosid) which is also called P vitamin. As well as it is known as the permeability factor or factor allowing permeability of the blood vessel. Rutin stimulates the C vitamin effect. Rutin has as well a high influence on hypertension, hypercholesterolemia and other cardiovascular diseases due to antioxidant properties. Buckwheat is the most important source of rutin. It is annual plant which belongs to Polygonaceae family and has a beneficial effect on human body. The common grown type is common buckwheat \kur{(Fagopyrum)}esculentum)} Moench) and less used type is buckwheat tartary \kur{(Fagopyrum tataricum)}. Tartary buckwheat \kur{(Fagopyrum tataricum)} contains several times higher amount of rutin than common buckwheat \kur{(Fagopyrum)}esculentum)} Moench). The highest amount of rutin is presented in the leaves and blossoms and the lowest one in seeds. Tartary buckwheat \kur{(Fagopyrum tataricum)} has much higher amount of rutin in seeds than common buckwheat \kur{(Fagopyrum)}esculentum)} Moench). The varietal differences in rutin content are considerable.
