Comparison of different doses and forms of selenium on its content in aboveground mass of cocksfoot (Dactylis glomerata L.)

Popis výsledku v původním jazyce

Selenium (Se) is an essential element that significantly influences the health status of animals and humans. Its adequate intake may affect the health, production and reproduction of livestock. The aim of this study was to determine the effect of foliar applications of selenium in different forms and doses on the content of selenium in the forage of cocksfoot (Dactylis glomerata L., cv. Dana). The experiment took place in a climate chamber. For foliar application comparisons, solutions of selenium at doses of 2 and 4 mg m-2 of Se (as selenate sodium or selenite sodium) were used. After the applications, samples of aboveground mass of each group were sampled at regular 14-day intervals. Samples were analysed by atomic absorption spectrometry. After successful foliar application of selenium, a significant (P&lt;0.05) increase of selenium content in aboveground mass of cocksfoot was found. No difference was found between selenite and selenate after application of the lower doses (2 mg m-2). In comparison with selenite, selenate showed significantly (P&lt;0.05) higher efficiency of accumulation of selenium (dose 4 mg m-2) in the aboveground mass. The lower doses of selenium were also effective and pose a lower risk than higher doses of selenium.
