INFLUENCE OF THE TECTONIC KNOTS IN THE NORTH OF THE RUSSIAN PLATE ON THE ENVIRONMENT STATE AT THE MICROLEVEL (BY THE EXAMPLE OF THE CONTENT OF ASCORBIC ACID IN BLUBERRY AND COWBERRY FRUITS)

Abstract

The study is an addition to a series of articles on the results of monitoring studies on the impact of tectonic knots on the state of the environment in the region. The knots of tectonic dislocations are a link between the abiotic (geological) and biotic environments, and have a significant impact on the state of vegetation cover, both at the macro and micro levels. This article shows the regularity of the content of ascorbic acid (vitamin C) in blueberries and cowberries, depending on their spatial location within the tectonic knot. It was revealed that the concentrations of vitamin C in berries selected in the center and on the periphery of tectonic knots differ. For example, its content in blueberries from the center of the Kholmogory tectonic knot is 37% higher than in berries from the periphery of the same knot. In the fruits of blueberries from the center of the Plesetsk tectonic knot – by 59%, and in cowberries – by 62% more, compared with the periphery. In the fruits of cowberries from the center of the Velsko-Ustyansky tectonic knot – 58% more. These knots differ from each other in geomorphometric, geological, tectonic factors, etc., which allows us to conclude that deep factors influence the state of the environment in general and the concentration of vitamin C in blueberries and cowberries in particular.
