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 Lathyrus vernus (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.
