DESCRIPTION:Speakers: Elena Khramova (Central Siberian Botanical Gardens\,
  SB RAS)\nA study has been first made of the element composition of both t
 he plants of two species of the genus Syringa\, growing under technogenic 
 impact in Novosibirsk and the soil samples from their habitat by method of
  X-ray fluorescence analysis using synchrotron radiation (SRXRF) at the st
 ation of element analysis of SCSTR of the Institute of Nuclear Physics SB 
 RAS (VEPP-3 store ring).   \nThe material studied was represented by the p
 lants of two species - Syringa josikaea and S. vulgaris\, represented by t
 hree cultivars: ‘Nadezhda’\, ‘Olimpiada Kolesnikova’\, ‘Pamjat o
  Kirove’\, growing in conditions of technogenic impact and background\, 
 collected in August of 2017 in Novosibirsk.   \nA comparative analysis of 
 the soil from the points of sampling of plant samples showed an excess in 
 the content of V\, Zn\, Br\, Pb and a decrease in Mn in urban soils compar
 ed with the background.   \nThe study of the content of macro- and microel
 ements in the aerial organs of representatives of the genus Syringa showed
  that the concentration of macroelements K and Ca is higher in the leaves 
 than in the stems\, regardless of the taxon and place of growth.   \nThe h
 ighest total content of K and Ca is revealed in the leaves of S. josikaea.
  It was found that in plants under technogenic impact\, the content of Mn\
 , Fe\, Co\, Cr\, Br\, Rb\, Nb increased and Zn and Mo decreased compared t
 o the control\, the most severe heavy metal pollution in urban conditions 
 was observed in plants of S. josikaea.   \nThe biogeochemical transformati
 on coefficient (Zv) was calculated\, which reflects a violation of the nor
 mal ratios of elements in the organs of plants as a result of increased an
 thropogenic load. The most significant changes in the elemental compositio
 n of lilac leaves under anthropogenic impact were observed in plants of th
 e species S. josikaea\, whose Zv of leaves is 37.2\, which is 1.3–1.6 ti
 mes higher than in plants of S. vulgaris. Plants of the ‘Memory of Kirov
 ’ variety (Zv = 22.8) are most resistant to pollution.   \nAs a result\,
  reliable data were first obtained on the content of 20 elements in sample
 s of two species of the genus Syringa in the urban ecosystem of Novosibirs
 k. The species and cultivars that are most tolerant to pollution in urban 
 conditions\, which can be recommended for widespread use in green construc
 tion\, are identified. The data obtained on the elemental composition of p
 lant samples and soils may be included in the databases. This work is part
 ially supported by RFBR grant № 16-44-040204.\n\nhttps://indico.inp.nsk.
