ЕLEMENT COMPOSITION OF <i>LATHYRUS VERNUS </i>(<i>FABACEAE</i>)
By method of X-ray fl yuorescencent analysis using of synchrotron radiation (RFA SI) Content of 19 chemical elements in vegetative and generative organs <i>Lathyrus vernus </i>(L.) Bernh. and in soils, which he sprouts was studied. Th e change of element composition during a vegetation period is shown. Th e coeffi cients of biological accumulation of microelements (KBN) showing the degree of their concentration.
