Abstract
In this investigation a selenium uptake and distribution in grapevine organs were estimated.
The experiment was conducted in field condition with brown forest soil.
This soil type in our country usually indicates a pronounced deficiency of selenium (120–320 μg/kg). The soil was fertilized with Na2SeO4, where the selenium was added as Ø kg Se/ha, 0,5 kg Se/ha and 1,5 kg Se/ha respectively.
Investigated variety was Cabernet sauvignon grafted on Kober 5BB rootstock.
Three separated plants were used as an experimental treatment, so, at the end of experiment, nine separated plants were analysed.
Duration of experiment was from March to the end of September, when the plants were taken from vineyard and after separation of organs (root, trunk, shoots, leaves, berries) were analysed.
The analysed plants positively corresponded to the applied selenium fertilizer with significant increase of its concentration, especially in leaves and berries.
According to the Se content in control plants (0.02–0.12 μg/g), the highest dose was most efficient in grape leaves having 10.41 μg/g of selenium, while the wooden mass of plants was less affected by Se fertilization.
The distribution of Se indicate a polar distribution of this element in grapevine plants.
