Abstract
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 (Na2SeO4). 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.
