In this investigation selenium uptake and its distribution in parts of one-year old apple trees were estimated. The experiment was conducted under glasshouse conditions, where the 10 kg pots were filled with brown forest soil. The soil was fertilized with Na2Se/O4, where selenium added as 0 kf Se/ha, 0.5 kg Se/ha and 1.5 kg Se/ha, respectively. Nine pots were planted with Melrouse apple cultivars (grafted on M 9 rootstock), with 3 trees in each treatment. The analysed plants positevely correlated with the applied selenium fertilizer with significant increase of its concentration, especially in roots, bark of rootstock and leaves. According to the Se content in organs of control plants (0.03-0.04 microgram/g), the highest dose was most efficient (root 20.8 microgram/g, bark of rootstock 0.78 microggram Se/g, leaves 0.72 microgramSe/g), while the wood mass of plants was less affected by Se fertilization (rootstock 0.10 microgram/g, scion 0.0 microgramSe/g). The distribution of Se indicates a polar distribution of this element in apple plants.
