“…Forest plantations are often degraded near cities, industrial enterprises and transport communication systems. Diagnostic of anthropogenic disturbance of forest ecosystems is currently detailed at all levels of living organization (Korshikov 1996;Monitoring and Adjustment… 2011). However, assessment and comparative analysis of causation are complicated.…”

The aim of our work was to establish the dependence of species composition, features of ecosystem distribution in the space and wood-destroying activity of xylotrophs on the functional type of forest, and the cause and degree of its violation. Changes in species composition, spatial distribution and wood-destroying activity of xylotrophic fungi, and disruption of “woody plant xylomycobiont”, “substrate category – xylomycobiont,” were revealed. Changes in xylotrophic diversity in stands were evaluated by diversity indices. Forest and taxonomic characteristics of stands, the reasons and the degree of degradation of forest ecosystems were taken into account. The ability of 37 species of xylotrophs to be indicators of deciduous and coniferous forests in green areas of cities due to recreation, construction and quarrying of granite has been substantiated. The principles of application of the mycoindicators system for improvement, a technique of estimation of character and degree of forest ecosystem anthropogenic transformation, are defined.

“…A negative effect on generative system development could be caused by (i) overwetting and drought (Velisevich, 2017), (ii) weather conditions in years when the generative structures were initiated and developed (Pukkala et al, 2010), (iii) the sum of positive temperatures during summer in the North of Eurasia (Fedorkov, 2007), (iv) species biological features (Lyanguzova, 2011), and (v) genetic traits of the populations (Hisamoto & Goto, 2017). In addition, many researchers have reported increases in the disturbance of male and female pine generative systems in areas of technogenic pollution (Tretyakova & Noskova, 2004;Kalashnik et al, 2008;Vasilevskaya & Petrova, 2014;Korshikov et al, 2015;Chropenova et al, 2016;Makhniova, 2016;Mohnachev et al, 2016;Makhniova et al, 2017). High levels of heavy metals and other elements might also be a factor in increasing abortive pollen frequency in plants (Reshetova et al, 2015;Chropenova et al, 2016).…”

In the conditions of environmental pollution by emissions of magnesite production (Combined Magnesite, Satka, Chelyabinsk region), a study of the conjugate variability of signs of the female generative system of the Scots pine (Pinus sylvestris L.) was carried out. Signs with a stable connection have been identified, as well as signs whose direction of interconnection changes under the influence of aerotechnogenic pollution. Thus, the relationship of the signs characterizing the size and mass of cones is rigidly genetically determined and is not violated in conditions of a strong level of pollution. The seed productivity of the pine stands, regardless of the growing conditions, is more closely related to the survival rates of ovules in the gametophytic period than in the period of embryonic development. However, in conditions of heavy pollution, the relationship between the survival of ovules in the 1st vegetative and embryonic periods is negative, which may indicate the effective elimination of abnormal gametophytes and the release of the stand from them in conditions of pollution. The strong weakening of trees and the low availability of mineral resources in conditions of high pH of the growing medium in the zone of heavy pollution cause an increase in the negative relationship between seed productivity and seed weight to a significant level. Also, the conditions of heavy pollution “contributed” to the development of a strategy of trees for the formation of small seeds with high quality and quality indicators, seedlings developed. Only in these growing conditions, with a decrease in seed weight, the indicators of germination energy, germination percentage, and morphometric indicators of seedlings significantly increased.

“…Yegorkina [14], the pollen from the background area (10 km from the source of pollution) had a higher percentage of pollen fertility and accumulated greater amounts of nutrients and physiologically active compounds than the pollen at the distance of 1 km from the urban industrial zone. Depression of the pollen grain viability potential in arborous and herbaceous species in the anthropogenic environmental conditions has also been revealed in a number of other investigations [15][16][17][18]. Recently, a series of studies have been undertaken with the view to assess the environmental situation in various urban industrial areas, on the basis of intensity of the gametocidal action on plant species [19][20][21][22].…”

Abstract. This research was conducted to study pollen quality in woody plants in the city parks of Dnipro, which are located at various distances from the sources of anthropogenic pollution. It has been revealed that sterile pollen in its greatest abundance was present in plant species in the Park of Memory and Reconciliation and Molodyozhny park, as both are situated within the range of emission transfer from the Western Industrial Complex, while the least abundant sterile pollen was detected in the park named after Yu. Gagarin and that named after V. Dubinin. According to sterility indices, the pollen in Betula pendula Roth. and that in Acer platanoides L. were most sensitive to environmental pollution. In the city parks, the amounts of shrunk and abnormally shaped pollen grains increases; giant forms with grain diameters exceeding standard, as well as dwarf forms are not rare in occurrence. The highest percentage of pollen grains of atypical shape and size was observed in the same parks where the pollen sterility index had its highest values.
