Изменение содержания белка у растений люцерны посевной Мedicago sativa L. под влиянием загрязнения почвы нефтью и рекультивации с применением препарата «Елена»

Abstract

The study of the adaptive mechanisms of plants in response to the action of oil makes it possible to identify signs that ensure the resistance of plants in conditions of oil pollution, with the aim of using them in the development of methods of reclamation and selection of plants resistant to oil pollution for it. The available data on the effects of petroleum hydrocarbons on plants are highly controversial. The species diversity of plants capable of growing on oil-contaminated soils has not been sufficiently studied. Phytoremediation is the most suitable soil purification tool for agricultural areas due to the large extent of the land and the relative cheapness of the method. Physiological, biochemical and morphometric parameters are important indicators of plant resistance to hydrocarbon pollutants. Of great scientific and practical interest is the identification of the resistance of higher plants to exogenous petroleum hydrocarbons (HC) and the identification of the effect of phytoremediation and the effect of the introduction of biological products in case of hydrocarbon pollution of the soil. The aim of the work was to assess changes in the biochemical and morphometric parameters of Medicago sativa L. plants under conditions of soil pollution with oil and reclamation using the biological product "Elena". Determination of the protein content in leaves makes it possible to judge the status of nitrogen metabolism in plants. It was revealed that oil pollution led to a decrease in the protein content of the plant Medicago sativa L. The use of the biological product "Elena" led to the restoration of this parameter. The results showed that the positive effect of the studied biological product depends on the concentration of the pollutant.
