ABSTRACT
: The possible occurrence of a redox-mediation within the soil–plant relation, characterizing the soil from the vicinity of the (aproximately 20) plants as well the herbaceous mass, through a global biochemical parameter, the rH, has been checked. At the same time, the content of etheric oils has been estimated refractometrically. A certain dependence of soil’s rH (characterized by a considerable variability) has been observed, for both the tissular rH and the content of etheric oils. As previously observed for other biochemical parameters, this depensence is of compensatory-type, that is, according to derivative I of the direct dependence, is manifested at the level of biomass accumulation.
