The element composition of both bush cinquefoil (Pentaphylloides fruticosa), growing in the Russian Far East (Primorsky krai, Amurskaya oblast) and East Siberia (Buryatiya, Irkutskaya oblast), and the samples of soils has been studied by the method of X-ray analysis using synchrotron radiation (SR XRF) at the station of element analysis of the Shared-Use Center SSTRC Budker Institute of Nuclear Physics, SB RAS (VEPP-3 storage ring). The goal of the work was to investigate the interpopulation variability of the element composition of P.fruticosa and to reveal populations with a high content of macro- and microelements. No less than 21 elements were determined (K, Ca, Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, As, Se, Br, Rb, Sr, Y, Zr, Nb, Mo, Pb). The maximal content of macroelements (K, Ca) was , as a rule, recorded in leaves and that of microelements was found in stems independent of natural habitat. The highest content of Fe, Ti, Zn, Ni, Pb, Nb, Co was determined in the stems of the plants of the Primorsky krai, that of Cr, Zr, Sr and Br was found in the plants of Buryatiya, and the highest content of Y and V was recorded in the plants growing in the Irkutskaya oblast. Mn was accumulated mainly in the leaves of the plants of the Amurskaya oblast, Rb was found in the plants of the Irkutskaya oblast and Cu, Мо and Se – in the plants of Buryatiya. The high content of Fe, Co, Ni, Cu, Rb, Zr, Pb in plants correlates with their content in the soils of sampling sites. Most stable is the content of Ca, K and Cu (СV= 8 – 20%) in the plants of various habitats. The variability of the rest elements of P. fruticosa is estimated as high and very high. In this case, the populations exhibit a small spread of element content (about an order of magnitude) which may be conditionally assigned to narrow samplings. The concentrations of Ni and Mo in the leaves of P. fruticosa vary by two orders of magnitude. The calculated mean geometric values of the element content in the leaves and stems of P. fruticosa of the populations studied are typical of the species, may be applied in a comparative analysis with other plants, may be used to standardize the vegetable staff and may be included in the data base.

The reported study was funded by RFBR according to the research project  No.16-34-00699-мол_а.
