Iron accumulation in leaves and shoots of Betula Pendula, Tilia Cordata L., Populus Pyramidalis in reaction zones of small towns of Lipetsk region

As a result of the studies, in the reaction zones of small towns of the Lipetsk region, Yelets, Zadonsk, Lebedyan, an assessment was made on the iron content in the leaves and shoots of Betula Pendula, Tilia Cordata L., Populus Pyramidalis. The following conclusions were made: Fe - according to the accumulation gradient, most of all accumulates in the leaf apparatus Populus pyramidális, in Betula pendula, Tilia cordata, the accumulation dynamics is identical, both in the leaf apparatus and in shoots, the accumulation.
