    The aim of this study was to investigate the effects of selenium (Se) on the growth, accumulation and possible mechanisms of Se transport in certain parts (roots, leaves, stamp and apex) of nettle (Urtica dioica L.) plants. Se was supplemented by one-shot and two repeated doses to the soil (2.0 and 4.0 mg Se per kg of substrate). Selenium content in roots increased linearly with dose and was significantly higher compared to other plant parts of interest. However, growth of the above-ground parts of plant as well as roots was slightly inhibited with increasing selenium concentration in comparison to the untreated plants. The content of phytochelatin2, a low molecular mass peptide containing a sulfhydryl group, correlated well with the Se content. This suggests a possible stimulation of synthesis of this plant peptide by Se

    CZECH PRIVATIZATION: PLAYERS AND WINNERS

    No full text
    This paper is focused on behaviour of different groups of economic agents participating in large scale privatization. Since large scale privatization has many interactions with other privatization programs, we will also briefly describe restitutions, small scale privatization and property transfer to municipalities. We will present descriptive analysis of rules and procedures of large scale privatization, identify the most important bidders for privatized property and analyze strategies they can use within given rules. On sample of 201 firms we will demonstrate use of those strategies by different bidders and their relative success in the process
