Abstract

The article presents the results of assessing the biochemical diversity of English oak trees in the forest-steppe zone of the european part of Russia. It is shown that at the beginning of the growing season in young oak leaf blades the most significant fluctuations in the levels of accumulation of substances of secondary metabolism occur, and by the end of the growing season their content stabilizes. It was revealed that flavonols are quantitatively the leading group of secondary metabolites. In the leaves of control trees, their content is 3.156 ± 0.113% of dry weight. It has been proven that an increased level of content of various groups of substances of secondary metabolism takes part in the formation of the potential biochemical resistance of trees when growing in adverse environmental conditions.
