“…In a number of articles (Miron, Sumalan, 2015;Mikhailova et al, 2017;Afanas' eva, 2018;Bessonova, Grytsay, 2018), it has been shown that chlorophyll reacts sensitively to all changes in the metabolism and, in adverse conditions, changes in its total content (a + b) and the ratio of individual forms (a/b). As for such an indicator the amount of chlorophylls (a + b) we should note that the results of author's research in general are the same as others: in the needles of P. abies from Ussuriisk, it was 1.11-1.38 mg/g of wet weight (Titova, 2010), and in the needles of P. pungens from the city of Dnipro (Ukraine), it was 0.99-1.7 mg/g of wet weight (Bessonova, Ponomar' ova, 2017).…”

“…In the first place, the conifer damages manifest themselves at the physiological and biochemical levels (Starikova et al, 2016) and then extending to the ultrastructural and cellular level changes. And only afterwards, there develop visual signs of plant damage, namely, chloroses and necroses of needle tissues, needle fall, and decrease in needle length and growth of lateral shoots (Bacic et al, 2003;Pavlov 2005;Mikhailova et al, 2017). This susceptibility is explained by the fact that most important physiological processes are carried out in the assimilation apparatus, which is the center of variability or plasticity of the organism (Shubert, 1988).…”

“…The widely used indicators of needle damage caused by air pollution is the decrease in the chlorophyll content, as well as the difference in its a and b forms and carotenoid changes (Tausz et al, 1996;Lepedus et al, 2003;Bessonova et al, 2004). Many foreign and domestic authors discuss the physiology of the impact of harmful emissions from industrial enterprises (Lepedus et al, 2003;Mikhailova et al, 2017) and vehicle exhaust gases (Verma, Chandra, 2014;Bessonova, Ponomar'ova, 2017) on the pigment content in coniferous plants.…”

Fedorchak E.: Influence of pollution on photosynthesis pigment content in needles of Picea abies and Picea pungens in conditions of development of iron ore deposits. Ekológia (Bratislava), Vol. 39, No. 1, p. 1-15, 2020. We studied photosynthetic pigments in needles of Pісеа аbies and P. pungens in plantings exposed to aerotechnogenic influence of various levels in the big industrial center of steppe zone of Ukraine (Kryvyi Rih). We analyzed the pigment content in needles of the second year of life sampled from 30 to 40-year-old trees of both species in 6 monitoring sites for 5 months. For the needles of P. аbies and P. pungens from all the sites, we noticed the decreasing content of chlorophyll a (to 27.2 and 25.0%, respectively) and chlorophyll b (to 17.9 and 20.0%, respectively) from May till September, in comparison with background territory. At the same time, the content of carotenoids performing the protective function in photosynthetic reactions increased up to 26.1 and 24.0%, respectively. For P. аbies and P. pungens growing in conditions of intensive technogenic pressure, we ascertained that, during investigations, the sum of chlorophylls (a + b) rate decreased to 24.4 and 23.6%, respectively; ratio (a/b) decreased to 11.4 and 12.3%, respectively; ratio (chlorophylls [a + b]/carotenoids) also decreased to 30.1 and 38.0%, respectively, in comparison with plants from the least polluted site. It is shown that the most intensive negative influence on plantings is caused by industrial pollution and exhaust gases: the minimum or, more rarely, the maximum rates of pigment content appeared in needles of the plants exactly from these sites. Our research results demonstrate the feasibility of using the pigment complexes of P. аbies and P. pungens, with the assimilative apparatus sensitive to air pollution damage, as indicators of air environmental conditions.

“…В то же время пропорции «Ch1a/Ch1b» и «(Ch1a+Ch1b)/Каротиноиды» растут по сравнению с фоновыми значениями, в первом случае за счет снижения уровня Ch1 b, во втором случае за счет снижения уровня каротиноидов. Выявлены средние, сильные и очень сильные обратные корреляционные связи между содержанием в хвое S, F, Hg, Pb, Cd, Fe, Al и уровнем пигментов (r = от -0,51 до -0,95) [79].…”

The present publication is the first of four reviews of reports that have been published over the last 20 years to address the responses of arboreal plants at different hierarchical levels of their organization to anthropogenic factors. The publication covers the effects of different kinds of industrial pollution on macro- and micromorphology of broad and acerose leaves. The specific and nonspecific responses of arboreal plants to the same factor or to different factors, including smokes and toxicants, are differentiated. The adaptive responses within a single leaf or needle may be relatively independent from each other despite the integrity of these plant organs. The causes of such diverse reactions, which ensure the adaptive potential of plants, are discussed with account for the multiplicity of biological functions required for maintaining plant tolerance to anthropogenic impacts.
