COMPARING CAREX SPECIES OF MID-FOREST SPRING ECOSYSTEMS IN TERMS OF ABILITY TO ACCUMULATE MACRO- AND MICROELEMENTS

Abstract

The aim of the research was to compare the accumulative macro- and microelements in the shoots of Carex acutiformis, Carex echinata, Carex paniculata, Carex remota and Carex rostrata. The content of components in the shoots of the plants was analyzed as to the chemical composition of the soil. The research was done within the area of four mid-forest spring niches situated in the valley of a tributary of the Słupia River situated within the area of Leśny Dwór Forest Inspectorate (Northern Poland). The examined species of Carex, in comparison to other plants in spring niches, were characterized by an average capacity to accumulate both macro- and microelements, which decides about little interest in these species when planning artificial buffer zones. From among the analyzed species, the shoots of C. echinata accumulated the largest quantities of Mg, Zn and Mn, the shoots of C. paniculata of Fe, C. remota K, Ni, Al and Sr respectively, C. acutiformis of N and P, and the shoots of C. rostrata of Ca and Cu. Similarities between the species of Carex, which resulted from their accumulative properties, were discovered. C. echinata and C. rostrata were characterized by high levels of bioconcentration factors (BF) for Sr, Cu and Ca and the low BF for K. C. paniculata and C. remota represented high BF levels for Ni and Mg and low BF levels for Sr, Al, Mn, Cu, Ca, Fe and N. C. acutiformis was characterized by high BF levels for P, K and Mn. In spite of an average accumulative capacity, the examined species of Carex were characterized by highly developed above ground and underground zones which had effective impact on the retention of pollutants.
