Abstract. The paper examines the influence of industrial emissions of sulphur (IV) and nitrogen (IV) oxides (the southern industrial zone of the city of Dnipro) on stem histological parameters of the autochthonous woody plant species undergrowth of Acer platanoides L. and Fraxinus excelsior L., which are natural forest edificators in the steppe zone of Ukraine. It shows that stem anatomical characteristics undergo quantitative changes in the annual undergrowth shoots of the two tree species under anthropogenic burden, with the most significant changes in the area of heavy pollution. Results indicate the decrease of such stem parameters as stem and stele diameters, wood radius and primary cortex thickness under high concentrations of SO 2 and NO 2 in seedlings of both species. However, this parameter drops in A. platanoides stems by reducing the collenchyme width, whereas it goes down in F. excelsior stems due to cork thickness loss. Another difference in the response of A. platanoides to the influence of phytotoxic pollutants compared to F. excelsior is the depletion of conducting elements of its phloem, which results in thinning the secondary cortex of the stem. The research findings prove high vulnerability of A. platanoides undergrowth to the chronic exposure of SO 2 and NO 2 . Therefore, this woody species is suggested to be used as a test object in monitoring research on plants of virginal group in the technogenic areas contaminated with sulphur (IV) and nitrogen (IV) oxides.

Landscaping of modern cities is impossible without increasing the area of green planting, which performs the function of turning the environment into more health-friendly one. Especially valuable are the species of ornamental plants that have high volatile activity. Because volatiles regulate the balance of pathogenic microflora in the air of cities, they significantly improve people's living conditions. According to the results of a previous study it was found that Thuja occidentalis L. and Th. plicata Donn ex D. Don f. “Zebrina” had the highest bactericidal activity during the winter among members of the family Cupressaceae. Given the frost, wind, gas and smoke resistance of Th. occidentalis, the aim of the study was to investigate the dynamics of phytoncide activity of the needles of this tree species during the year in a relatively clean zone and under the influence of vehicle emissions on plants in the urban ecosystem of Dnipro. The material was collected in all seasons of the year at two monitoring points in Dnipro, which differ in the level of environmental pollution by vehicle emissions. Traffic intensity was determined by the Potichuk & Pilipaka method. Antimicrobial action of Th. occidentalis was studied by the method of placing the crops of microbial test cultures under the effect of volatile secretions of needles and evaluating the result on a scale of phytoncide activity. The test subjects were Staphylococcus epidermidis, Staphylococcus aureus, Micrococcus sp., Bacillus subtilis, Esherechia coli, Pseudomonas fluorescens, Candida albicans. Studies have shown that in a relatively clean area and under the action of traffic loads, the inhibitory effect of needles on the studied strains of microorganisms changes during the year: in winter it is the smallest, in spring begins to grow, in summer is maximum, and in autumn decreases again. Under the man-made growth conditions, the greatest volatile activity of Th. оccidentalis performs on test objects such as: S. aureus, Micrococcus sp. and E. coli. When affected by car load, there is significant inhibition of phytoncide production by needles in the presence of C. albicans, to a lesser extent – Ps. fluorescens and B. subtilis. It is recommended to use Th. оccidentalis in landscaping of urban areas with moderate traffic.

“…Діаметр первинної кори у пагонах дослідного варіанта в її вужчих частинах становить 120,5% від контролю, а у ширших -87,5%, що пов'язано з неоднаковими змінами товщини паренхіми первинної кори, можливо, неоднаковими темпами поділу клітин. Аналогічні результати щодо збільшення товщини коленхіми у пагонах Salix alba L. отримали Jusypiva and Miasoid (2016). Проте, якщо в дослідах цих авторів спостерігали потовщення також і паренхіми первинної кори, то у пагонів Q. rubra за дії полікомпонентних забруднювачів відбуваються різноспрямовані зміни ширини цього гістологічного елемента первинної кори стосовно показників контролю залежно від місця розташування.…”

Air pollution is one of the important problems of large cities. In connection with this, comprehensive study of the mechanisms of the corresponding reactions of tree species, introduced in the process of landscaping, to various environmental factors is required. The aim of this study is to analyze the influence of urban technogenic environmental pollution on the anatomical characteristics of Quercus rubra Linnaeus, 1753 annual shoots. The object of research was 35-year-old plants of Q. rubra, which grew in a non-polluted site (conditionally clean zone), the Botanical Garden of DNU (plot 1) and in a polluted site (roadside planting) (plot 2) of Dnipro City. Industrial emissions of the city's western, northeastern and northwest industrial complexes also have an effect on plants, depending on the wind direction. For anatomical research, the annual shoots were taken at the tips of the vegetation from the south-eastern side of the model trees at a height of 2 m and fixed in 70% alcohol. Cross sections were made at a distance of 1 cm from the beginning of growth. Phloroglucine was used to dye the cells. The influence of industrial and automobile emissions on the structural parameters of Q. rubra shoots was investigated. We established that the membrane thickened evenly in both control and experimental plants. Cork thickness of Q. rubra shoots, growing in the roadside plantation was higher than in plants of the Botanical Garden by 57.5%. Increasing its thickness in plants exposed to atmospheric air pollution has an adaptive value. Q. rubra shoots have a tabulate type of collenchyma, the tangent walls of whose cells thicken. The collenchyma cells of the control variant of shoots are larger. This tissue was thicker in Q. rubra shoots from the polluted site by 26.8% compared to those from the non-polluted zone. The parenchyma cells of the primary cortex were large and contained chloroplasts. The thickness of this histological element on the shoot circumference varied considerably both in the control and experimental variants, which is the result of its uneven formation. This is due to the fact that the shape of the shoot core resembles a pentagonal star, and the layers of phloem and xylem tissues repeat its shape. The thickness of each of them in the cross section of the shoots in various places varied little, while the parenchyma of the primary cortex above the ray cells was narrower, and between them was broader, as a result the thickness of the shoots was aligned in a circle. In areas where the parenchyma of the primary cortex was narrower, it was better developed in the shoots of experimental plants than the control ones, but where its layer was thicker, it was more developed in plants of the control variant. The diameter of the primary cortex in the shoots of the experimental variant in its narrower parts was 120.5% of the control, and in the broader -87.6%, which is due to unequal changes in the thickness of the primary cortex parenchyma, possibly with different rates of cell division. In the one-year Q. rubra shoots...
