Popis:	The experiment with the use of selenium fertilizer (sodium selenate) on low SE brown-forest soil (183 μg/kg) was conducted with red raspberry (Rubus idaeus) under field conditions. Selenium was added in the following doses: 0 kg Se/ha,.5 kg Se/ha, 1.5 kg Se/ha and 0.1 % foliar application of Se-salt (Na 2SeO4). Selenium reserves in floricane (120 cm) were obtained by Se fertilization in previous vegetation. The uptake and distribution of Se in raspberry roots, floricanes, primocanes, leaves and bramble-fruits were determined in current vegetation. The highest dose significantly changed Se concentration from 0.02 μg/g to 0.21 μg/g in roots, 0.32 μg/g in floricanes, 1.10 μg/g in primocanes, 1.81 μg/g in leaves and 0.65 (μg/g in brambles. Foliar treatment was efficient too, but the used SE concentration (0.1%) induced necrotic spots on leaves.
