Nemereshina O.N., Gusev N.F. THE INFLUENCE OF MAN-CAUSED POLLUTION ON FLAVONOID CONTENTS IN PLANTS OF FIGWORT CLASS OF STEPPE PREDURALIE The contents of biologically active substances in plants depend of physical and chemical characteristics of habitat - ecological factors. Flavonoids take up special place among substances of repeated synthesis. It is supposed that flavonoids raise plants tolerance to unfavourable conditions of environment. The studying of plants of fig-wort class (Veronica spicata L., Linaria vulgaris L., Melampyrum pratense L.), which were collected in steppe Orenburzhie in a zone of influence of Orenburg gas-transfering plant industrial outbreaks, allowed to determine that contents of flavonoids sum in plants biomass, which grew in a zone of acting of atmospheric outbreaks of Orenburg gas-transfering plant, exceeded the quantity of flavonoids in plants biomass of control part. This fact testifies about changes of metabolic processes way and phytochemical plant structure, which have to be adapted to pollute with industrial gas outbreaks surroundings.
