This article presents the results of a study on the morphological parameters of common bilberry (Vaccinium myrtillus<\/em>\u00a0L.) and the content of photosynthetic pigments (chlorophyll\u00a0a<\/em>, chlorophyll\u00a0b<\/em>) in its leaves within plant communities at different stages of secondary succession after clearcutting (clearcut, maturing forest, overmature forest). The research was conducted in the middle taiga subzone. Forest edges, as transitional areas between clearcuts and maturing forests, were additionally investigated. On 19 sample plots, the measurements of illumination and photosynthetic photon flux density (PPFD) of photosynthetically active radiation (PAR) were carried out, bilberry projective cover was assessed, and the maximum shoot height was measured. The content of photosynthetic pigments in bilberry leaves was determined. The illumination and PAR levels, measured in clear and cloudy weather, decreased along the gradient: clearcut \u2013 forest edge \u2013 forest community. The lowest projective cover and shoot height of the dwarf shrub were recorded on the clearcut and forest edge, while the highest values were found under the forest canopy. The content of photosynthetic pigments (chlorophyll\u00a0a<\/em>, chlorophyll\u00a0b<\/em>) in bilberry leaves was minimal under the most illuminated conditions of the clearcut and forest edge and differed significantly from the conditions under the canopy of maturing and overmature forests.<\/span><\/p>\n
