The content of photosynthetic pigments in 30-day-old shoots of Scots pine grown under the influence of acetone extracts from lichens Hypogymnia physodes, Evernia prunastri, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula was studied. Extracts were on the surface of the substrate of seed germination and under it. With direct contact of sprouts of Pinus sylvestris with extracts from Hypogymnia physodes, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula, an increase in the content of chlorophylls and carotenoids, a change in the ratios of chlorophyll a: chlorophyll b and chlorophyll: carotenoids. Extracts from Evernia prunastri did not affect the photosynthetic pigments production and the relationship between them. With the indirect contact of seedlings with extracts from lichens, Hypogymnia physodes, Ramalina pollinaria, Xanthoria parietina and Cladonia arbuscula noted a sharp increase in the content of chlorophylls and carotenoids, a change in the relationship between them. Extracts from Evernia prunastri inhibited the chlorophylls synthesis, enhanced the carotenoids production, did not affect the relationship between pigments.
