Peculiarities of the pigment system functioning of moss Campylopus introflexus (Hedw.) Brid. depending on habitat conditions of the mine “Nadiia” dump top in Chervonograd industrial coal mining region of Lviv region were analyzed. Also seasonal dynamics of plastid pigments and photochemical activity of isolated chloroplasts of the moss in adverse conditions of technogenic environment were established. It was noted that the decrease in the ratio of a/b chlorophylls and the increase of chlorophylls to carotenoids in conditions of the suppression of the chlorophyll photochemical activity play an important role in protection of the photosynthetic system of C. introflexus.
Keywords: plastid pigments, photochemical activity of chlorophyll, rock dumps of coal mines, moss Campylopus introflexus
