The Pollen of Plants of the Shrub Layer in the Urban Green Space as an Indicator of the State of Atmospheric Air of the City (on the Example of Representatives of the Genus Forsythia)

Abstract

It is established that the pollen of F. suspense is sensitive to a complex of exogenous factors of the growing environment in the park ecosystems of Kyiv. The statistical significance of the complex influence of plant growing factors and weather conditions on the variability of F. suspensa pollen quality traits and its sizes has been confirmed. There is a greater influence of air pollutants in the surface layer of atmospheric air on the size of the equatorial diameter of the pollen grains of this plant species. Introduction of restrictive anti-epidemic measures in 2020 and 2021 has reduced the level of integrated air pollution in most of the studied areas of the capital. These changes in the conditions of the growing environment, especially in the absence of the influence of the developed network of highways, affected the share of abnormal grains in pollen populations in the studied areas.

The expediency of further use of plants of F. suspensa to assess the state of the environment on a toxic-mutagenic background and zoning of park ecosystems on a gradient of anthropogenic impact is noted.
