Testování tolerance vybraných genotypů konopí vůči fytotoxickým účinkům zinku
Kabina, Viktoriia
This bachelor thesis was aimed at testing the tolerance of selected hemp genotypes to the phytotoxic effects of zinc. In the theoretical part, the main aspects of the toxic effect of heavy metals on plants were analyzed. Here the sources of environmental contamination with heavy metals, the uptake of heavy metals by plants, the effects of heavy metals on plants and their tolerance mechanisms are described, and the phenomenon of phytoremediation as a method of soil purification is also described. In the practical part, the influence of different zinc concentrations on selected hemp genotypes, namely French variety Felina 32 and Hungarian variety Monoica, were studied. The growth parameters of the experimental plants and the pigment content in the leaves of the plants were determined. The experiments did not prove serious effects of zinc on experimental plants, except for high concentrations in individual cases. Nevertheless, it can be said that in comparison with the Monoica variety, representatives of the Felina 32 variety were more sensitive to the presence of zinc in the soil.
