FEATURES OF MICROELEMENTS AND LOW-MOLECULAR WEIGH ANTIOXIDANTS ACCUMULATION IN PLANTS OFTHE GENUS ROSA L.

Abstract

Wild roses are an important group of plants used as row material for pharmaceutical, cosmetic and food industries. The aim of this study was to determine the microelements (Mn, Fe, Zn, Cu, Cr, Ni, Pb, Co, Cd) content and distribution in the aboveground and underground parts of the Rosa acicularis, R. davurica, R. rugosa, growing in Baikal region. It was found that R. rugosa plants are characterized by a higher Cu content and a low level of Mn; the hips of these plants also accumulate Fe, Zn, and Co. In the sepals, leaves, stems and roots of R. davurica the highest concentrations of Fe are noted, and in the vegetative and generative organs of R. acicularis – Cr. Transport of Zn, Cu, Ni in aboveground parts of plants is mainly acropetal, the remaining elements translocation in basipetal direction. Cd belongs to the elements of strong accumulation in plants of all three species, in addition, species-specific features of some elements accumulation in aboveground and underground organs are revealed. It was found that the fruits, leaves, and stems of Rosa acicularis and Rosa rugosa can serve as a potential source of Mn, Cr, and Co.
