Abstract:

Inoculation of Platanus × acerifolia stems with Ceratocystis fimbriata f.sp. platani, the canker stain disease agent, induced the accumulation of preexisting phenolic compounds such as flavan-3-ols and proanthocyanidins in the infected internode of the stem. These flavan compounds and their polymerized products were most quickly accumulated near the inoculation site, particularly in the medulla, vascular tissues, tyloses, and gels. Thus, these plane tree reactions were considered as defensive responses. Their involvement in the restriction of Ceratocystis fimbriata f.sp. platani development around the inoculation site, associated with other located responses previously described, was discussed. Keywords: Ceratocystis fimbriata, flavan-3-ols, Platanus × acerifolia, proanthocyanidins.

Abstract:

The experiments were performed to establish the conditions of <i>Platanus</i> × <i>acerifolia</i> Willd. and <i>Salix alba</i> L. cv. 'Tristis' reproduction by tissue culture. Two experiments were run. Leaf buds of <i>Platanus </i>and inflorescence buds of <i>Salix</i> were used. Growth of callus from <i>Platanus</i> and <i>Salix</i> in dependence on the concentration of growth substances (BA and NAA) and light and darkness conditions were compared. Rooted explants of <i>Salix alba</i> L. cv. 'Tristis' were obtained. The best results were obtained with <i>Platanus</i> × <i>acerifolia</i> in which rhizogenesis of amorphic callus occurred after two months of the experiment. Darkness was not a necessary condition for root formation. After three months of the experiment completely developed <i>Platanus</i> × <i>acerifolia</i> plants were obtained composed of a foliated shoots and a bundle of roots. They could be planted out on a sterile permanent substrate.

Abstract:

The purpose of this study is to analyse the physiology of Platanus acerifolia buds, especially latent buds that are exploited by urban prunings. Biological and biochemical tests have allowed us to observe the following: (i) The dormancy of the 1-year-old twig buds is weak and characterized, in November, by a mediobasitonic gradient of bud bursting ability. During the dormancy period, the latent buds have the same capacity to bud break as buds from the proximal part of 1-year-old twigs. The dormancy of the latent buds is weak but accentuated with bud ageing. (ii) The inhibition of the 1-year-old twig proximal buds is particularly detected during the dormancy period. Whatever the month, the latent buds are not able to develop unless the axis and the more distal buds above them are eliminated. (iii) The buds keep their intracellular properties (5,5′-dimethyloxazolidine-2,4-dione accumulation) if the axis above them is intact. (iv) The growth of the hybrid plane tree is characterized by a weak acrotony as well as a weak apparent endogenous rhythmicity. This growth is influenced by external factors, especially rainfall. Key words: buds, latent buds, dormancy, growth, 5,5′-dimethyloxazolidine-2,4-dione, Platanus acerifolia.

Full text

Abstract:

The assessment of mature urban tree vitality using physiological measurements is still in its infancy. Chlorophyll fluorescence is a method for assessing tree vitality that has potential for use in urban environments, particularly on trunk bark, which is easy to access from the ground. Here we describe how we compared bark and leaf fluorescence in a variety of street and park trees (Ficus macrophylla Pers., Platanus × acerifolia (Aiton) Willd., and Ulmus parvifolia Jacq.) with pre-dawn water potential as a way of determining the cause of potential physiological stress in the summer of 2012. Statistical relationships were observed between bark chlorophyll fluorescence and pre-dawn water potential in Ficus macrophylla and Platanus × acerifolia, but were not as consistent in Ulmus parvifolia. In addition, bark and leaf chlorophyll fluorescence were compared with an urban visual vitality index both in autumn 2011 and summer 2012. In this case statistical relationships between bark chlorophyll fluorescence values and urban tree visual vitality were almost non-existent in the Ficus macrophylla and Platanus × acerifolia trees, however, statistical relationships were significant between bark chlorophyll fluorescence and the urban tree vitality index in Ulmus parvifolia. Bark chlorophyll fluorescence may become a useful tool for measuring physiological stress in trees, but further work needs to be undertaken to clarify and better understand the varying responses of different tree species.

Full text

Abstract:

The sycamore lace bug, Corythucha ciliata (Say) is a highly invasive pest insect that feeds on sycamore trees (Platanus spp.) worldwide. The interaction between Platanus species and this insect pest has not yet been studied at the molecular level. Therefore, a recent study was conducted to compare the gene expression and metabolite profiles of Platanus acerifolia leaves in response to C. ciliata feeding damage after 24 and 48 h. We employed high throughput RNA sequencing (RNA- seq) to identify a total of 2,828 significantly differentially expressed genes (DEGs) after C. ciliata feeding. In addition, 303 unigenes were found to be up-regulated at both time points. Moreover, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis showed that monoterpenoid biosynthesis, the linoleic acid metabolism pathway, and alpha- linolenic acid metabolism were the most prominent pathways among the DEGs. Further analysis of the metabolite profiles showed that nine metabolites were significantly different before and after C. ciliata damage. In addition, we analyzed DEGs detected in the P. acerifolia and C. ciliata interaction using Mapman. The terpene synthase gene family was also identified. We suggest that the results obtained from DEGs and metabolite analysis can provide important information for the identification of genes involved in the P. acerifolia–C. ciliata interaction, which might be necessary for controlling C. ciliata efficiently.

Full text

Abstract:

Transcription and alternative splicing (AS) are now appreciated in plants, but few studies have examined the effects of changing ploidy on transcription and AS. In this study, we showed that artificially autododecaploid plants of London plane (Platanus × acerifolia (Aiton) Willd) had few flowers relative to their hexaploid progenitors. Transcriptome analysis based on full-length Oxford Nanopore Technologies (ONTs) and next-generation sequencing (NGS) revealed that the increased ploidy level in P. × acerifolia led to more transcribed isoforms, accompanied by an increase in the number of isoforms per gene. The functional enrichment of genes indicated that novel genes transcribed specifically in the dodecaploids may have been highly correlated with the ability to maintain genome stability. The dodecaploids showed a higher number of genes with upregulated differentially expressed genes (DEGs) compared with the hexaploid counterpart. The genome duplication of P. × acerifolia resulted mainly in the DEGs involved in basic biological pathways. It was noted that there was a greater abundance of alternative splicing (AS) events and AS genes in the dodecaploids compared with the hexaploids in P. × acerifolia. In addition, a significant difference between the structure and expression of AS events between the hexaploids and dodecaploids of Platanus was found. Of note, some DEGs and differentially spliced genes (DSGs) related to floral transition and flower development were consistent with the few flower traits in the dodecaploids of P. × acerifolia. Collectively, our findings explored the difference in transcription and AS regulation between the hexaploids and dodecaploids of P. × acerifolia and gained new insight into the molecular mechanisms underlying the few-flower phenotype of P. × acerifolia. These results contribute to uncovering the regulatory role of transcription and AS in polyploids and breeding few-flower germplasms.

Abstract:

For steppe cities, it is important to replenish the range with durable decorative species that grow quickly and form a three-dimensional crown. Such plants due to the shading of large areas create more comfortable living conditions for people in steppe cities. These species include London planetree (Platanus acerifolia Willd.), which sporadically began to be planted in some cities in the postwar period. The viability of P. acerifolia in the steppe is different. Since the biological peculiarities of this introduced species have been studied in various socio-economic problems in cities, we conducted a comparative analysis of the vital state and biometric parameters of P. acerifolia in the plantations of two cities of the steppe zone of Ukraine. We found out that P. acerifolia is widely used in landscaping of Kherson, while in Kryvyi Rih it is rare. In Kherson, the species is distributed near administrative buildings, schools, hospitals; it grows in parks, squares and yards of high-rise buildings, and in Kryvyi Rih only in one subdistrict and in the arboretum of the Kryvyi Rih Botanical Garden. The trees in Kherson are aged 38–60. The vital state is estimated as high and close to high – 77.8–96.3%. Older trees are 18.4–21.5 m of height and a maximum trunk diameter is 80.1–99.4 cm. Plants of all plantations in Kherson have dry branches, with a rate of 6.3–28.7%. In Kryvyi Rih, 28–42-year-old trees grow. In different plantations of P. acerifolia, the number of dry branches varies in the range of 0.3–44.5%, and the vital state – from 55.5 to 100% depending on the place of growth. The height of P. acerifolia trees is 6.2–20.3 m, and the trunk diameter is 12.2–68.7 cm. The study has proved that the differences in vital state and morphometric parameters of trees in the plantations of these cities depend on the age of trees, their planting density, lighting and other growing conditions. Trees in Kryvyi Rih are more significantly damaged by cold winds than in Kherson.  The life form of P. acerifolia in the plantations of Kherson and Kryvyi Rih is almost everywhere a single-stemmed tree. This species is beginning to naturalize in the conditions of Kherson. Several plants of self-seeding origin were found during the research studies. Restoration of plants with young sprouts produced by stumps after cutting the plant trunks in Kherson was also noticed. The leaf apparatus of plants during the growing season is practically not damaged by diseases and pests and no slimy stains are formed on the leaves.  We determined that P. acerifolia is a promising species for wider use in landscaping of the cities of the Black Sea coast and settlements of the Right-Bank Steppe, but in the latter case requires successful selection of exhibition sites for successful growth. These, first of all, should be cozy places protected from the effects of cold winds in winter and dry winds in spring and summer.

Abstract:

This study assessed leaf fluxes of CO2, CH4 and biogenic volatile organic compounds (BVOC) for two common urban tree species, Platanus × acerifolia (exotic) and Schinus molle (native), widely distributed in Santiago, Chile. The emission factors (EF) and the Photochemical Ozone Creation Index (POCI) for S. molle and P. × acerifolia were estimated. The global EF was 6.4 times higher for P. × acerifolia compared with S. molle, with similar rates of photosynthesis for both species. Isoprene represented more than 86% of the total BVOCs leaf fluxes being 7.6 times greater for P. × acerifolia than S. molle. For P. × acerifolia, BVOCs represented 2% of total carbon fixation while representing 0.24% for S. molle. These results may suggest that plant species growing outside their ecological range may exhibit greater BVOCs leaf fluxes, proportional to photosynthesis, compared to well-adapted ones. The results found may contribute to better urban forest planning.

Full text

Abstract:

The rapid development of an efficient root system resulting from arbuscular mycorrhiza formation is essential to the successful establishment of many plant species. We have analysed root system development and used histochemical staining to define relationships between lateral root order dynamics, arbuscular mycorrhiza development, and the physiological state of the symbiotic fungus Glomus fasciculatum (Thaxter sensu Gerdeman) Gerd & Trappe amend. Walker and Koske, in a woody plant species Platanus acerifolia Willd. Arbuscular mycorrhiza induced modifications in root system development in P. acerifolia, compared with nonmycorrhizal root systems. Third-order lateral roots dominated in arbuscular mycorrhizal plants, while second-order laterals were most numerous in nonmycorrhizal systems. Arbuscular mycorrhiza colonization was closely related to the appearance of different root orders; the most active mycelium (characterized by fungal succinate dehydrogenase and alkaline phosphatase activities) was mainly localized in newly formed lateral roots. Nine weeks after inoculation with G. fasciculatum the proportion of alkaline phosphatase-active mycelium strongly decreased in all root orders, and this was related to an increased phosphorus content of the host plant. The dynamics of development of the arbuscular mycorrhizal fungus and the possible regulation of its activity by the host plant are discussed. Keywords: arbuscular mycorrhiza, fungal enzyme, root system morphology, Platanus acerifolia, Glomus fasciculatum.

Abstract:

London planetrees (Platanus × acerifolia, syn. P. × hispanica), American sycamores (P. occidentalis), and oriental planes (P. orientalis) are widely planted as urban shade trees throughout Greece and many other countries. In June 2012, typical symptoms of a powdery mildew were detected on all sycamores (10 trees) along a central avenue of Heraklion (Crete, Greece), with the disease affecting approximately 80% of the leaves of all infected trees. In August 2013, similar symptoms were observed on 20% of the leaves of all three London planes in a small grove in the Vrysses area of Lasithi (Crete, Greece). In both cases, the disease was severe, with white superficial colonies developing amphigenously on leaves, twigs, floral peduncles, inflorescences, and fruits. The colonies were initially distinct and circular but gradually enlarged and often coalesced to cover the entire leaf blade. Young leaves appeared curled and chlorotic, occasionally leading to defoliation. For the morphological description of the pathogen, samples from seven infected P. occidentalis and three P. × acerifolia trees were microscopically characterized. In all samples, the pathogen's mycelium was branched, septate, and hyaline, with lobed appressoria; conidiophores were erect, cylindrical, unbranched, and consisted of three to four (to five) cells; and conidia were single or in short chains (two to four), ellipsoid or doliiform, with a truncated base and rounded apex. Their dimensions were 24.3 to 48.6 × 15.8 to 27.9 μm (averaging 39.2 × 21.2 μm; n = 100), and their surfaces appeared reticulate. The teleomorph was never observed. Total fungal DNA was extracted from conidia harvested from affected leaves of one infected plant of each of P. occidentalis and P. × acerifolia planes, and the ITS1-5.8S-ITS2 region was PCR-amplified with universal primers 18S-ITS1 and 28S-ITS2 (2) and sequenced (GenBank Accession Nos. KM068123 and KM068124, respectively). A BLASTn search of GenBank revealed 100% identity of both samples to Erysiphe platani strains described on P. orientalis in Greece (JQ365943) and P. occidentalis in Brazil (KF499270). Based on the morphological and molecular analyses, the pathogen was identified as E. platani (Howe) U. Braun & S. Takam. (formerly known as Microsphaera platani Howe) (1). To prove pathogenicity and fulfill Koch's postulates, 10 1-year-old seedlings of each of P. occidentalis and P. × acerifolia hosts were artificially inoculated with conidia obtained from naturally infected plants of the corresponding species, with two methods: (i) five plants of each host were dusted with conidia from diseased leaves, and (ii) the remaining five seedlings of each plane were sprayed with a conidial suspension of the fungus (107 conidia ml−1), while five additional control plants of each species were treated only with sterile distilled water. All plants were maintained in the greenhouse at 25 ± 3°C, with 90% humidity. Powdery mildew symptoms, which appeared 9 and 15 days after inoculation on all dusted and sprayed plants, respectively, were similar to those observed on naturally infected trees, whereas no symptoms were observed on control plants. Although E. platani is known to infect plane species in several parts of the world (1), including oriental planes (P. orientalis and P. orientalis var. cretica) in Greece (3), this is the first report of E. platani causing disease of P. occidentalis and P. × acerifolia in Greece, underlining the need for appropriate control measures to prevent significant losses to the local ornamental industry.

Abstract:

Empregada na arborização urbana em muitas cidades, a árvore Platanus acerifolia Willd. (Platanaceae) está sujeita à ação de insetos fitófagos, dentre esses, o xilófago Pantophthaulmus pictus (Wiedemann, 1821) (Diptera: Pantophthalmidae), conhecido popularmente como mosca-da-madeira, que pela ação de sua larva broqueia seu fuste. Portanto, este trabalho objetivou registrar e caracterizar os danos de P. pictus no fuste de P. acerifolia. Para tanto, foram analisados três indivíduos de P. acerifolia empregados na arborização urbana e cultivados a dez metros um do outro, e somente dois apresentavam orifícios de emergência de P. pictus no fuste. A morfometria e a distância do solo dessas lesões foram mensuradas com uso de paquímetro e fita métrica, respectivamente. O diâmetro médio dos orifícios de emergência de P. pictus nas árvores um e dois foi: 0,84 e 0,72 cm, respectivamente. A profundidade média das galerias foi de 9,22 cm na árvore um e 9,57 cm na árvore dois. A altura média em relação ao solo dos orifícios no fuste foi de 180,62 cm na árvore um e 105,02 cm na árvore dois. Não houve registro de orifícios na copa. Aplicando-se o teste T (p < 0,05), verificou-se que não houve diferença estatística significativa nesses valores entre árvores. Na árvore um, observou-se o parasitismo proporcionado pela erva de passarinho, sendo este indivíduo arbóreo categorizado como o mais gravemente danificado pela ação do inseto (32 orifícios), em comparação com a árvore dois (6 orifícios). Sugere-se que o estresse vegetal possa influenciar na suscetibilidade de P. acerifolia à ação de P. pictus.

Abstract:

The B-BOX (BBX) gene family is widely distributed in animals and plants and is involved in the regulation of their growth and development. In plants, BBX genes play important roles in hormone signaling, biotic and abiotic stress, light-regulated photomorphogenesis, flowering, shade response, and pigment accumulation. However, there has been no systematic analysis of the BBX family in Platanus × acerifolia. In this study, we identified 39 BBX genes from the P. × acerifolia genome, and used TBtools, MEGA, MEME, NCBI CCD, PLANTCARE and other tools for gene collinearity analysis, phylogenetic analysis, gene structure, conserved domain analysis, and promoter cis-element analysis, and used the qRT-PCR and transcriptome data for analyzing expression pattern of the PaBBX genes. Collinearity analysis indicated segmental duplication was the main driver of the BBX family in P. × acerifolia, and phylogenetic analysis showed that the PaBBX family was divided into five subfamilies: I, II, III, IV and V. Gene structure analysis showed that some PaBBX genes contained super-long introns that may regulate their own expression. Moreover, the promoter of PaBBX genes contained a significant number of cis-acting elements that are associated with plant growth and development, as well as hormone and stress responses. The qRT-PCR results and transcriptome data indicated that certain PaBBX genes exhibited tissue-specific and stage-specific expression patterns, suggesting that these genes may have distinct regulatory roles in P. × acerifolia growth and development. In addition, some PaBBX genes were regularly expressed during the annual growth of P. × acerifolia, corresponding to different stages of flower transition, dormancy, and bud break, indicating that these genes may be involved in the regulation of flowering and/or dormancy of P. × acerifolia. This article provided new ideas for the study of dormancy regulation and annual growth patterns in perennial deciduous plants.

Abstract:

Platanus × acerifolia (Aiton) Willd. (London planetree) is a tree commonly used as an ornamental and in the furniture industry. In the summer of 2013, powdery mildew was observed on shoots of P. × acerifolia plants in the cities of Pelotas and Canela (State of Rio Grande do Sul, Brazil). Voucher specimens (n = 2) were deposited in the Phytopathological Museum Manoel Alves Oliveira at Federal University of Pelotas. Dense white powdery masses of conidia and mycelium were observed on leaves (abaxial and adaxial surfaces), petioles, and young stems. Leaves with high disease severities (≥70%) were deformed with curved edges to the adaxial side, and they often died. Mycelia were superficial with lobed appressoria. Conidiophores were straight, sometimes curved at the base, unbranched, cylindrical, 98 to 236 μm long (137.3 ± 41.2 μm) and composed of a cylindrical foot cell 49 to 102 μm long (66.9 ± 19.5 μm) and 4.4 to 6.4 μm wide (5.3 ± 0.8 μm) followed by two to four cells. Conidia were produced singly or in short chains (two to three), without distinct fibrosin bodies, ellipsoid to ovoid and measuring 24 to 37 μm long (29.5 ± 3.2 μm) and 12 to 19 μm wide (15.2 ± 1.4 μm), often with a wrinkled appearance. Primary conidia had truncate bases and rounded apex while both base and apex were truncated in secondary conidia. Germ tubes were produced apically (pseudoidium type). Chasmothecia were not observed. Genomic DNA was used to amplify the internal transcribed spacer (ITS) region using the ITS1 and ITS4 primers. The resulting sequence (602 bp) was deposited (Accession No. KF499270) in GenBank. BLASTn searches revealed similarity of 100 and 99% with Erysiphe platani from P. orientalis L. (Accession No. JQ365943.1) and P. occidentalis L. (Accession No. JX997805.1), respectively. Phylogenetic analysis placed our sequence in a clade (99% bootstrap support) which included only other E. plantani sequences. In short, morphological and molecular approaches allowed us to identify the infecting fungus as E. platani. For Koch's postulates, 10 detached leaves were inoculated (10 to 15 conidia cm2) on their adaxial surface using an eyelash brush. Non-inoculated leaves served as control. All leaves were kept inside trays with petiole immersed in humidified cotton and maintained at 25 ± 1°C. Symptoms identical to those of the original leaves were observed 6 to 8 days after inoculation, whereas the control leaves remained symptomless. Although E. platani has been previously reported on P. × acerifolia in the city of Poços de Calda, state of Minas Gerais, Brazil (1) and on P. occidentalis in Korea (2), to our knowledge, this is the first record of E. platani on P. × acerifolia in Rio Grande do Sul, Brazil.

Abstract:

O presente trabalho teve como finalidade estudar o efeito do ácido indol-3-butírico (AIB) no enraizamento de estacas caulinares de diferentes diâmetros de Platanus acerifolia (Aiton) Willdenow. Para tal, foram utilizadas estacas finas (diâmetro médio 0,94 cm); médias (diâmetro médio de 1,58 cm) e grossas (diâmetro médio 2,75 cm), submetidas a dois tratamentos: T1 (testemunha) e T2 (6000 ppm de AIB em talco). A aplicação da auxina foi por meio de talco na base das estacas, sendo plantadas em substrato constituído de uma mistura de matéria orgânica vegetal, areia grossa de rio e de solo Unidade Santa Maria - Podzólico Bruno-acinzentado ( 1:2:7, v/v ). As estacas foram mantidas em casa de vegetação com sistema de micropulverização. Após 120 dias foram avaliados os seguintes parâmetros: número de estacas enraizadas, número de raízes formadas, comprimento médio das raízes formadas (em cm) e número de folhas. Pela análise dos resultados obtidos, concluiu-se que o tratamento com AIB (6.000 ppm na forma de pó) influenciou significativamente no processo de enraizamento das estacas, sendo as estacas grossas as que apresentaram as melhores respostas. Por isso, são as mais indicadas para a reprodução por estaquia em Platanus acerifolia (Aiton) Willdenow.

Abstract:

With the accelerated process of urbanization, air pollution has become increasingly severe. Garden plants can trap atmospheric particulate matter, which is of great significance for improving the urban ecological environment and promoting sustainable development. To investigate the dust retention effect of typical transportation green spaces in Nanjing, this study focuses on thirteen garden plants on Xuanwu Avenue in Nanjing. The dust retention capacity of these plants was determined using the wash-off method, while the microstructure of their leaf surfaces was observed using scanning electron microscopy. The results are as follows: Firstly, per unit leaf area, Liriope spicata, Ophiopogon japonicus, and Viburnum odoratissimum demonstrate solid dust retention abilities. Additionally, Viburnum odoratissimum, Prunus serrulata var. Lannesiana, and Liriope spicata show strong dust retention abilities per single leaf. Moreover, Platanus acerifolia, Viburnum odoratissimum, and Cinnamomum camphora have strong dust retention abilities per plant. Viburnum odoratissimum, Platanus acerifolia, and Prunus serrulata var. Lannesiana exhibit the most substantial dust retention capacities. Secondly, there is a significant negative correlation between dust retention per plant and the potassium content, while a significant positive correlation is observed with plant height, canopy height, and leaf width. Furthermore, there is a highly significant positive correlation between dust retention per unit leaf area and stomatal length and a highly significant negative correlation with leaf length. The surface microstructure of the blade mainly increases the dust retention capacity of the blade by increasing the friction of the leaf surface. Lastly, specific leaf surface microstructures, such as grooved epidermis and trichomes, enhance plants’ dust retention capacity. Consequently, for the future configuration of road green spaces in Nanjing, a mixed planting mode of trees, shrubs, and grass is recommended. Priority should be given to selecting plants with strong overall dust retention capabilities, such as Platanus acerifolia, Viburnum odoratissimum, and Prunus serrulata var. Lannesiana, to alleviate air pollution, improve the urban ecological environment, and achieve sustainable development.

Abstract:

Despite the rapid advances in drug R&D, there is still a huge need for antibacterial medications, specifically for the methicillin-resistant Staphylococcus aureus (MRSA). Inspired by the research where a viable class of MRSA inhibitors was found in the species Platanus occidentalis, a S. aureus inhibition screening-guided phytochemical reinvestigation on Platanus × acerifolia (London plane tree) leaves were performed with four flavonoid glycosides garnered, including two new compounds, quercetin-3-O-α-l-(2″-E-p-coumaroyl-3″-Z-p-coumaroyl)-rhamnopyranoside (E,Z-3′-hydroxyplatanoside, 1) and quercetin-3-O-α-l-(2″-Z-p-coumaroyl-3″-E-p-coumaroyl)-rhamnopyranoside (Z,E-3′-hydroxyplatanoside, 2). All of the isolates showed significant S. aureus ATCC 25904 inhibitory activity with MICs ranging from 4 to 64 μg/mL, suggesting the potential of discovering drug leads for the control of S. aureus from such a rich, urban landscaping plant in the Platanus genus.

Abstract:

The effect of nighttime lighting on the anatomical and morphological structure and the content of photosynthetic pigments in the leaves of Tilia cordata, Aesculus hippocastanum, and Platanus acerifolia was estimated on the example of garden-park and street plantings of Kyiv. At the experimental sites, the level of illumination and the soil surface temperature during the day and night periods were examined. The anatomical and morphological structure of the leaves was studied using transmission electron microscopy. The content of photosynthetic pigments (chlorophylls and carotenoids) in tree leaves was determined spectrophotometrically.The analysis of variance revealed that nighttime lighting significantly affected the anatomical structure and the content of photosynthetic pigments in the leaves of T. cordata and P. acerifolia. In A. hippocastanum, only parameters of stomata and palisade parenchyma showed a significant reaction to this stress factor.
