COMPARATIVE STUDYING OF INFLUENCE OF EMISSIONS OF MOTOR TRANSPORT ON THE GREEN MOSSES AND MACROMYCETES GROWING IN ROADSIDE FOREST PHYTOCENOSES OF THE EUROPEAN PART OF RUSSIA
O.D. Volkova

Six forest roadside plant communities were studied (including broad-leaved, small-leaved and coniferous forests in different
regions of the European part of Russia (from the Novgorod region in the North to the Voronezh region in the South), were
found 13 species from 10 genera of green moss on the ground and on tree trunks. In all investigated phytocenoses there is
a General trend of increasing power (thickness) of moss cover and biomass in terrestrial green mosses as the distance from
the road. At the edge of the forest decline in biomass of green moss, can be explained as the harmful effects of motor vehicle
emissions and deterioration of plant conditions due to exposure to sunlight: humidity of moss cover is substantially lower
than at other sites. The decrease in the phytomass of mosses at the experimental sites, remote from the edge of the forest,
compared to the control, probably due to the infl uence of harmful emissions only. In epiphytic mosses observed a similar
trend: height of trunk covered with moss and moss incidence increases with distance from the source of contamination,
reaching a maximum at control sites. In all the studied forests with distance from the road increases the total number of
species of macromycetes.
Keywords: infl uence of emissions of motor transport; a wood roadside ecosystemes; green mosses; macromycetes; sensitivity
to pollution.
