Abstract
The purpose of this study was to determine the microelements (Mn, Fe, Zn, Cu, Cr, Ni, Pb, Co, Cd) content and distribution in the aboveground and underground parts of the Rosa acicularis, grown in different ecological conditions in the Barguzinsky district (the Republic of Buryatia). Atomic absorption spectrometry was used to determine the concentration of microelements. The highest concentrations of Zn, Cu, Ni, and Co are found in the roots of R. acicularis, Mn, Cr, Pb, and Cd in the leaves, and Fe in the sepals. The rows of metal accumulation in different plant parts have a similar sequence – Fe> Mn> Zn> Cu> Cr> Pb> Ni> Co> Cd. The different intensity of elements accumulation by plants from the soil was detected. It was show Fe, Mn, Cr, Pb and Cd transfer in vegetative parts of plants without barrier, while Zn, Cu, Ni, and Co are characterized by a barrier type of accumulation. Due to the high level accumulation of Mn, Cr and Co barriers can be used as a potential source of these elements.
