The accumulation of elements by plants depends on the species and varietal characteristics. A number of plant substances capable of complex formation can contribute to the phytoextraction of elements from soils. In amaranth, such a substance can be the betacyanine pigment amaranthine. Amaranth varieties containing amaranthine accumulate toxic elements from the soil. The results of our experiment showed that Amaranthus tricolor var. "Valentina" on soils with varying degrees of anthropogenic pollution can actively extract Mn, Fe, Ni, Sb. This ability of red-colored amaranth varieties can be used for phytoremediation of contaminated soils from toxic elements, and should also be taken into account when grown for nutrition and processing on contaminated soils of agricultural lands. The maximum accumulation of toxic elements from soils among the studied aboveground organs was found in amaranth leaves. The minimum is in the stems. This paper belongs to the MOSM2021 Special Issue. Using the INAA method, the ability of Amaranthus tricolor L. variety “Valentina” growing on soils with different degree of pollution to extract heavy metals was evaluated in the field experiments. It was found that amaranth of the studied variety characterized by the content of betacianin pigment, amaranthine, in the shoots and generative organ, is able to accumulate elements such as Mn, Fe and Ni from soils. The content of most of the studied elements decreases in the following order: leaves > inflorescences > stems. Under conditions of soil pollution with emissions from metallurgical plant, the phytoextraction of such elements as Mn, Fe, Co, Sb increases. The content of Fe and Mn in the leaves of A. tricolor var. “Valentina” exceeds the average data for vegetation from 7 to 17 times; the Co content exceeds the average data for vegetable from 4 to 7 times; the Sb content in the leaves exceeds the average data for vegetable from 10 to 23 times. Due to the fact that amaranth forms a sufficient biomass for the growing season, it can be recommended for phytoextraction of heavy metals from soils in case of polymetallic pollution. The study was carried out with the financial support by the Russian Foundation for Basic Research project No. 19-29-05257 “Technogenic soil pollution with toxic elements and possible methods for its elimination”. |
