Micropropagation involves the risk of somaclonal variation among the regenerated plants. It is possible that the components of the nutrient medium, especially growth substances, increase the frequency of variation. Elatior Begonia 'Barbara' plants we

Micropropagation is an efficient means of producing pathogen-free Elatior begonias. However, the growth of the micropropagated plants can be too luxuriant, flowering is often delayed and the root collars remain thin, all unwanted growth habits in com

Micropropagation is an efficient way to produce pathogen-free Elatior begonias. However, certain problems arise when these plants are used in commercial pot plant production. The plants grow too luxuriantly, the root collars remain thin and flowering

Data on the transfer of elements (such as heavy metals) and their radionuclides into organisms is needed for assessing environmental risks. The current data on many elements, species and environments is limited, but more information can be obtained b

Ants can influence ecological processes, such as the transfer of elements or radionuclides, in several ways. For example, they redistribute materials while foraging and maintaining their nests and have an important role in terrestrial food webs. Quan

Information on transfer of elements and their radionuclides is essential for radioecological modeling. In the present study, we investigated the transfer of Cl, Co, Mo, Ni, Se, Sr, U and Zn in a boreal freshwater food chain. These elements were selec
