DESCRIPTION:Speakers: Elena Khramova (Central Siberian Botanic Garden\, SB
  RAS)\nThe element composition of both bush cinquefoil (Pentaphylloides fr
 uticosa)\, growing in the Russian Far East (Primorsky krai\, Amurskaya obl
 ast) 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 Ce
 nter SSTRC Budker Institute of Nuclear Physics\, SB RAS (VEPP-3 storage ri
 ng). \nThe goal of the work was to investigate the interpopulation variabi
 lity of the element composition of P.fruticosa and to reveal populations w
 ith a high content of macro- and microelements.\nNo 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 macroe
 lements (K\, Ca) was \, as a rule\, recorded in leaves and that of microel
 ements was found in stems independent of natural habitat. The highest cont
 ent 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 t
 he plants of Buryatiya\, and the highest content of Y and V was recorded i
 n the plants growing in the Irkutskaya oblast. Mn was accumulated mainly i
 n the leaves of the plants of the Amurskaya oblast\, Rb was found in the p
 lants of the Irkutskaya oblast and Cu\, Мо and Se – in the plants of B
 uryatiya. The high content of Fe\, Co\, Ni\, Cu\, Rb\, Zr\, Pb in plants c
 orrelates with their content in the soils of sampling sites.\nMost 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 estimate
 d as high and very high. In this case\, the populations exhibit a small sp
 read of element content (about an order of magnitude) which may be conditi
 onally assigned to narrow samplings. The concentrations of Ni and Mo in th
 e leaves of P. fruticosa vary by two orders of magnitude. The calculated m
 ean 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 a
 pplied in a comparative analysis with other plants\, may be used to standa
 rdize the vegetable staff and may be included in the data base.\n\nThe rep
 orted study was funded by RFBR according to the research project  No.16-3
