Uptake of Selenium of Red Clover (Trifolium pratense)

The aim of this study was to determine the ability uptake of red clover (Trifolium pratense) forage of selenium after foliar application. There was established the pot experiment. Plants were placed in climabox with controlled-environment. In the experiment was selenium used in different forms (selenite and selenate) at a concentration equivalent to 4 mg.m-2 Se. Samples of aboveground biomass were taken 14th, 28th and 42nd day after foliar application of selenium. Samples were analyzed by atomic absorption spectrometry with continuous radiation source with high resolution ContrAA 700. The content of selenium was affected (P <0.05) also date of taking green matter and form of the applied selenium. Key-Words: perennial forage crops, selenite, selenate, pot experiment
