Eco-trophic Relationships and Frequency of Occurrence of Mycobiota of Some Trees grown on the Roadside: the Case of Baku Highways

Abstract

The current study is devoted to eco-trophic relationships and frequency of occurrence of fungal species involved in the formation of tree mycobiota along the highway. As a result, it was possible to determine the possibility of using determined indicators of tree mycobiota in assessing the environmental status of the area near the highway. With this purpose rhizosphere and mycobiota of the leaves of such trees as Platanus orientalis, Populus nigra and Pinus eldarica growing at various distances (10-100 m) from Baku highways with different traffic intensity have been studied. The samples were taken for the period from 2016 to 2018. The sensitivity of fungi species to pollution from the influence of motor transport has been evaluated. It has been established that the structure of micromycete complex spread both in leaves and rhizosphere of trees growing on the roadside is disturbed by the effects of highway. Near the highway the decrease of species diversity of fungi and increase of the number of dark-colored mycelium fungi species have been observed. This, in turn, leads to the disturbance of the ecological functions of roadside ecosystems. The possibility of using such species as A.fumigatus, Botryotrichum piluliferum, P.cuslopium, P.funiclozum, St.chartarum as indicators has been determined.
