Abstract
In the context of increasing anthropogenic impact on the environment, the study of the mechanisms of plant adaptation is an actual problem. To diagnose ecological troubles, it is advisable to study the indicators characterizing metabolic processes in autotrophic plants. The change in the parameters of the photosynthetic apparatus and antioxidant system in silver birch (Betula pendula), European spruce (Picea abies) and dandelion (Taraxacum officinale L.), depending on the intensity of anthropogenic load, was studied. The pigment composition of plants and the activity of antioxidant enzymes can be used as markers of the anthropogenic pollution level of a territory.
