ACCUMULATION AND DISTRIBUTION OF MICROELEMENTS IN ARCTOSTAPHYLOS UVA-URSI
Abstract
The main purpose of the study was to determine the microelements content (Mn, Fe, Zn, Cu, Cr, Ni, Pb, Co, Cd) in the aboveground and underground parts of Arctostaphylos uva-ursi grows in two forest types of the Republic Buryatia. Element content was measured by atomic absorption spectrometry (AAS, AAnalyst 400 PerkinElmer). It was found roots accumulate the most amounts of microelements. The row of the elements accumulation in the leaves, stems and roots have a similar sequence: Mn> Fe> Zn> Cr> Cu> Pb> Ni> Co> Cd; in berries zinc ranks the first place in the row. The different intensity of elements accumulation by plants from the soil was detected. Due to the high level of chromium accumulation Arctostaphylos uva-ursi can serve as a source of this element for the treatment and prevention of diabetes and atherosclerosis.
