STUDIA BOTANICA HUNGARICA (Antea: Fragmenta Botanica) XIX. . 1986 p. 53-61 Investigations on the trace element geochemical interaction between soil and vegetation; concentration of manganese, zinc, copper and lead in the soil and in Dactylis glomerata L. Hy Gy. SZAKMÁIM (Received AugUHt 1. 1W<>) Abstract: The author Investigated the trace clement content in Dactylis glomerata L. with rc spool Lo lour elements of spot-, a I importance in plant physiology (iWn, Zn, Cu, Pb), as well as their relation to the soluble trace clement content of certain levels of the soil sections deepened in the vicinity of the sampling sites. In course of the examinations it was found th >l the amount of manganese accumulated in Dactylis glomerata is not depending on the variation of the amount in the soluble manganese of the soil, the zinc present in Dactylis gl omerata is in correlation with the zinc content soluble from the upper part of the soil whereas that of lead is in close correlation with the amount of lead soluble from the lower part of the soil level. The amount of copper present in plants is in negative correlation with the amounl of copper soluble from the soil . INTRODUCTION The study of the relationship between the trace element content of the soil and the trace elements accumulated in plants is very important. The lack of certain trace elements in the soil, or its occassional superfluous abundance can influence the trace element balance of the plants growing on the soil proper. If the access ton given trace element is not sufficient, certain deficiency symptoms may occur, while a superfluous amount of certain trace elements can lend to a toxication of plants, and through the plants, of animals and even humans. Therefore it is very important to define the optimal amount of the individual trace elements for the plants as well as the amount of trace elements, especially that of the soluble trace elements present in the soil. If the distribution of the latter is unfavourable, certain procedures like artificial fertilization can help to influence it positively. To promote this type of research was the primary aim of this work. Similar studies were reported from several authors, among others REDOY, C.N. & PATRICK, W.H. (19771, JACKSON. K.S. & SK1PPEN, G.B. (1978), DAVIS. D. & BECKETT, P.H.T. 09781, HABLY, L. (1982).
