    Opis:
    This study examined the impact of air pollution, and more specifically the impact of traffic, on the health of urban trees. Due to the lack of data sets, urban tree growth modeling often relies on the existing knowledge of forest. However, urban trees differ from forest trees. One of the aims of the study is to fill the lacunae in this field. It was hypothesized that in streets with higher traffic volume, both growth parameters and health status of trees would be decreased in comparison to trees growing in streets with lower traffic volume. Four of the most common tree species growing in Berlin were selected: Tilia cordata Mill., Acer platanoides L., Platanus acerifolia (Aiton) Willd., and Aesculus hippocastanum L. Apart from the tree age and stand position (high and low traffic volume), the height and circumference were measured and the following traits were analyzed: trunk condition, crown defoliation, leaf discoloration, the presence of hollows and nests. The streets that were selected for the analysis were located in the center of Berlin. For each species, four streets with high traffic volume and four streets with low traffic volume were chosen. The car traffic volume had a significant impact on growth parameters. Significant differences in height and circumference between trees growing on streets with low or high traffic volume were noticed; the higher the traffic volume, the lower the tree height and circumference. This tendency is particularly visible in P. acerifolia, T. cordata and A. platanoides. This relation was observed in all species except for A. hippocastanum. In the conditions of high-traffic volume, A. platanoides is thriving revealing the smallest differences in vitali- ty and condition of the crown, trunk and leaves. The greatest differences in the health condition of the trees among the analyzed variants of traffic intensity were observed in the case of T. cordata. Lime trees seem to be most suitable for planting in the streets with lower traffic volume, whereas A. platanoides seems most suitable for planting in the streets with high traffic volume. P. acerifolia, despite its generally good health, is suffering from several progressing diseases. It is worth considering whether it should be gradually replaced with more resistant species. Aesculus, especially A. hippocastanum, are currently the most endangered ones. An alternative to this species can be A. carnea.

    Opis:
    This publication presents the influence of soil salinity on the abundance of aphids on the leaves of street trees in cities. The objects of research were trees of Crimean Linden (Tilia ‘Euchlora’) planted at Zwirki and Wigury Street in Warsaw. The research included the evaluation of the trees’ condition, the counting of the number of Lime Aphid (Eucallipterus tiliae L.), as well as the determination of chlorine and nitrogen content in the leaves. The research revealed a statistically significant influence of chlorine content in the leaves on the deterioration of their condition. The increased content of chlorine in the leaves was accompanied by a decrease in the number of aphids. This relationship was statistically significant. No nitrogen deficiency in the leaves was detected. No statistically relevant relationship between the nitrogen content and the condition of the trees was observed. There was a weak negative correlation which, however, was statistically insignificant. Using the regression function it was determined that the increase in chlorine content in leaves by 1% (from 1.0 to 2%) resulted in a decrease in the abundance of aphids by 49%. What is more, a statistically significant (p = 0.032) influence of nitrogen content on the abundance of aphids was proved. The increase of this element by 1% (from 2.5 to 3.5%) was accompanied by the increase in the number of aphids by 90%.
    Przedstawiono wpływ zasolenia gleby na liczebność mszyc na liściach drzew miejskich. Przedmiotem badań były drzewa z gatunku lipa krymska (Tilia ‘Euchlora’), rosnące w pasie międzyjezdniowym al. Żwirki i Wigury w Warszawie. Badania polegały na ocenie stanu zdrowotnego drzew, zliczaniu mszyc zdobniczki lipowej (Eucallipterus Tiliae L.) oraz na określeniu zawartości chloru i azotu w liściach. Stwierdzono statystycznie istotny wpływ zawartości chloru w liściach na pogorszenie ich stanu zdrowotnego. Zwiększonej zawartości chloru w liściach towarzyszyło zmniejszenie liczebności mszyc. W przypadku zawartości azotu w liściach nie stwierdzono występowania poziomów niedoborowych. Nie wykazano statystycznie istotnej zależności między zawartością azotu a stanem zdrowotnym drzew. Między zawartością chloru i azotu występowała słaba zależność ujemna, która jednak była nieistotna statystycznie. Na podstawie funkcji regresji stwierdzono, iż wzrost zawartości chloru w liściach o 1% (z 1,0 do 2,0%) powodował spadek liczebności mszyc o 49%. Wykazano także statystycznie istotny (p = 0,032) wpływ zawartości azotu na liczebność mszyc. Wraz ze wzrostem zawartości tego pierwiastka w liściach o 1% (z 2,5 do 3,5%) zwiększała się liczba mszyc o 90%.

    Opis:
    The main goal of this study was to identify the unique gene pool of old and historically valuable Quercus robur L. and Tilia cordata L. to be able to characterise their genetic diversity in order to determine the polymorphism by expressed sequence tag-single sequence repeat (EST-SSR) markers and identify the most valuable specimens. Morphological description, molecular genetic analysis, and statistical analysis were used in studies. The genetic distances between old-value trees of different Quercus L. and Tilia L. were determined based on EST-SSR markers and morphological characteristics. Using polymerase chain reaction (PCR), alleles of the expected size were obtained. It was determined that four to eight alleles were obtained by seven SSR markers in the studied Q. robur L. samples. According to the calculated value of the locus polymorphism index (polymorphism information content [PIC]), the most polymorphic was the marker SSRQrZAG 65; the PIC was 0.84. The lowest value of PIC was observed in the marker SSRQrZAG 11; the PIC was 0.69. Intragenetic polymorphism was detected for all studied markers. Among the studied samples of linden, two to five alleles were identified. It was found that the highest value of PIC was obtained for the marker Ts920 – 0.72. The least polymorphic was the marker Ts927 (PIC was 0.28), which is not only due to the small number of alleles, but also their uneven distribution in the sample. Intragenetic polymorphism was detected in four of the six markers analysed for T. cordata L. In this study, polymorphism was detected in all studied samples of Q. robur L. and T. cordata L., which allows to assess their genetic diversity based on the distribution of alleles.

    Opis:
    The aim of the study was to assess the susceptibility of small-leaved lime (Tilia cordata Mill.) seeds to drying and freezing in liquid nitrogen (-196°C). Seed samples were frozen in liquid nitrogen for 24 h at 11 different levels of seed moisture content (m.c.), ranging from 3.1% to 22.8% (fresh weight basis). All samples, including unfrozen control samples, were subjected to scarification with concentrated sulphuric acid (Tylkowski 1998) either before or after freezing. Seed pre-treatment before germination (at 3~15°C/16~8h) involved cold stratification at 3°C without substrate. Seed drying to 3.1% m.c. significantly reduced their germinability (to 63%), as compared to the high germinability (82-88%) of seeds with 5.2-20.9% m.c. Thus seeds of this species can be assigned to the ‘suborthodox' category. Such a high germinability (79-87%) was preserved after freezing in liquid nitrogen in samples dried to 9.0-17.4% m.c. if scarification was performed before freezing, and in samples dried to 9.1-16.2% m.c. if scarification was performed after freezing. The highest percentage of seedlings emerged after freezing in liquid nitrogen from seeds dried to 11.1-20.1% m.c. (emergence 65-75%) if scarification was performed before freezing, and from seeds dried to 7.3-17.8% m.c. (emergence 53%-71%) if scarification was performed after freezing.

    Opis:
    Soil contamination caused by the NaCl used to de-ice slippery roads in winter is now recognized as one of the major causes of nutrient disorders and death in urban trees. It is believed that polyisoprenoids may have a specific role in the adaptation of plants to adverse conditions and habitats; it is further believed that in the cell, they may exhibit a protective effect in response to biotic and abiotic stress. The aim of this study was to evaluate the effect of salt stress on the content of prenol lipids in the leaves of Crimean linden (Tilia ‘Euchlora’). The Cl content in the slightly damaged (“healthy”) leaves averaged 0.96%, while that in the heavily damaged (“sick”) leaves averaged 2.02%. The leaves of control trees contained on average 0.57% Cl. The Na contents in the healthy and damaged leaves were 208 mg/kg and 1038 mg/kg, respectively, and the Na content in the control areas was 63 mg/kg. A mixture of polyprenols consisting of four compounds, prenol-9, prenol-10, prenol-11 and prenol-12, was identified in the leaves of Crimean linden. This mixture was dominated by prenol-10 (2.16–6.90 mg/g). The polyprenol content was highest in the leaves of “healthy” trees (approximately 13.31 mg/g), was lower in the case of “sick” trees (approximately 9.18 mg/g), and was the lowest in the control trees (mean 4.71 mg/g). No changes were observed in the composition of the mixture of polyprenols under these conditions. The results suggest that polyprenols may affect the accumulation of Cl in leaves. This phenomenon is evidenced by the high content of prenols in the leaves of trees considered “healthy” but growing under conditions of increased soil salinity and the lower content of prenols in the leaves of the “sick” and control trees. It is advisable to further investigate the role of prenol lipids in the leaves of trees subjected to salt stress

    Opis:
    Fruits of large-leaved lime dried to 10% may be stored for 16 years in sealed containers at –3°C without loosing seed viability. Dormancy of seeds, extracted from hard fruit coats, may be released after chemical scarification in concentrated sulphuric acid for 10 minutes, followed-by stratification without any medium (chilling) at the temperature of 3°C, for 20–24 weeks, i.e. until the first seeds start to germinate. After such pretreatment, during the germination test conducted at alternating temperatures 3~15°C (16 + 8 hours/day) seeds germinate near 90% in several weeks. For seedling production scarified and stratified seeds should be sown in early spring into trays under a plastic tunnel which ensures a high percentage of seedlings emergence. Sowing of the pretreated seeds in spring in a open nursery gives poor results.

    Opis:
    This paper aims to explore the modern deposition of lime and maple pollen in various plant communities as compared to the results obtained in palynological analyses of the Holocene paleosols in Kaczórki (the Middle Roztocze) and the Błędów Desert which are characterized by very high amounts of the pollen of these trees. The research shows that a high annual deposition of both lime and maple pollen on the soil surface is possible. This deposition far surpasses the average pollen values recorded in the Holocene but is not as high as those recorded in fossil soils. In relation to paleosols in Kaczórki such results show that lime and maple were important components of forests surrounding dune and simultaneously point to the fact that the deposition of pollen in these soils was a complex process.

    The putative hybrid character of two Tilia varieties selected as avenue trees (‘Szent Istvan’ and‘K3’) should be clarified for further breeding activities. Their ancestor species should be identified by a genetic comparison with reference material (Tilia cordata, T. platyphyllos, T. dasystyla, T. × euchlora, T. × europaea and others). RAPD marker data were evaluated by UPGMA cluster and neighbour-joining analysis. The genetic comparison of the two selected clones with the collection of reference material offers insights into some systematic relationships within the genus Tilia. It was supplemented by a critical discussion of methods of RAPD data evaluation for taxonomic purposes.

    Opis:
    The aim of the study was to describe the relationships between the flowering phase of selected tree species, whose pollen is known to be allergenic, and fluctuations in the pollen in the air, and to use results obtained for making allergological forecasts. Studies were conducted of five tree taxa: Populus, Ulmus, Salix, Aesculus, and Tilia, in the years 2003-2004. Aeropalinological analyses concerned the above mentioned genera, while in phenological studies specific species were investigated, i.e. the most common representatives of a given genus found in Poland, that is Populus wilsonii, Ulmus laevis Pall. C. K.Schneid., Salix caprea L., Aesculus hippocastanum L. and Tilia cordata Mill. Aerobiological monitoring was performed using a the volumetric method and phenological observations of flowering phases were made according to the Lukasiewicz method. While observing the emergence of individual phenological symptoms and measurements of the concentration of pollen of the investigated taxa in the air of Poznań, a distinct acceleration was observed in 2004, a year that was characterized by a milder winter. This applied not only to the species blooming in early spring, but also to the later ones. Pollen grains of the investigated taxa, except for Aesculus, appeared earlier in aeropalinological observations than the macroscopically observed beginning of flowering in selected trees. Apart from a poplar, the end of flowering in the other trees occurred each year earlier than would follow from the aerobiological observations. This may be explained by the abundance of species within a taxon, and the effect of medium - and long-distance transport.
    Celem badań było wykazanie związku pomiędzy wynikami monitoringu fazy kwitnienia wybranych gatunków drzew, których pyłek działa uczulająco, a wahaniami zawartości aeroplanktonu w powietrzu oraz ich wykorzystaniu w przygotowaniu prognoz dla potrzeb alergologicznych. W latach 2003-2004 badano pięć taksonów drzew: Populus, Ulmus, Salix, Aesculus, i Tilia. Analizy aeropalinologiczne dotyczyły podanych rodzajów, a w obserwacjach fenologicznych badano konkretne gatunki, często występujących w Polsce przedstawicieli danego rodzaju: Populus wilsonii C. K. Schneid., Ulmus laevis Pall., Salix caprea L., Aesculus hippocastanum L. i Tilia cordata Mill. Monitoring aerobiologiczny prowadzono aparatem wolumetrycznym a obserwacje fenologiczne faz kwitnienia wykonywano metodą Łukasiewicza. Obserwując poszczególne pojawy fenologiczne oraz zawartość pyłku badanych taksonów w powietrzu Poznania, stwierdzono wyraźne ich przyspieszenie w roku 2004, cechującym się łagodniejszą zimą. Dotyczyło to nie tylko gatunków zakwitających wczesną wiosną, ale również i tych późniejszych. Ziarna pyłku badanych taksonów, oprócz Aesculus, pojawiały się wcześniej w obserwacjach aeropalino- logicznych, niż makroskopowo obserwowano początek kwitnienia wybranych drzew. Z wyjątkiem topoli, koniec kwitnienia pozostałych drzew przypadał rokrocznie wcześniej niż wynikało to z badań aerobiologicznych. Przyczynę tego można tłumaczyć bogactwem gatunków w obrębie taksonu oraz wpływem średniego i dalekiego transportu. Kontynuacja wspólnych badań może pomóc w prognozowaniu początku i pełni sezonu pyłkowego alergogennych gatunków drzew i krzewów, pod warunkiem, że badania będą prowadzone przez wiele lat.

    Opis:
    In 1970-2000, the state of the natural environment in many regions of Poland was unsatisfactory. This situation has been improving since the integration with the European Union, mainly owing to the reduction of emissions of sulphur and nitrogen oxides. The present study included three tree species: rowan (Sorbus aucuparia L. em. Hedl.), small-leaved lime (Tilia cordata Mill.), and aspen (Populus tremula L.). The trees grew in a pollution free environment (Huszlew) and in an urban agglomeration (Lublin). The aim of this research was to make comparative observations of the structure of leaves in relation to the content of lead, zinc, copper, nitrogen and sulphur determined in these organs. The N/S ratio in the leaves was accepted as an indicator of proper metabolic processes. Observations of leaves were made with using light microscopy and the scanning electron microscopy (SEM) technique. The content of heavy metals in leaves was determined by atomic absorption spectrometry (AAS) after dry mineralization. Total sulphur was determined by the turbidimetric method, while nitrogen by the Kjeldahl method after mineralization in sulphuric acid. When influenced by polluted air, the epidermis of the examined leaves was composed of smaller cells with higher stomatal density per unit area and had a lower number of open pores compared to the epidermis of the leaves developed in a clean environment. Among the species investigated, aspen was characterized by the highest ability to bioaccumulate heavy metals in its leaves. Among the elements determined only the Zn content exceeded the permissible limit, whereas Pb and Cu were found to occur in the range of values considered to be optimal. The dominant share of lead in suspended dust caused changes in the epidermis of leaves, which led to disorders in plant water relations.

    Opis:
    The study concerns the ecological responses of Tilia cordata Mill. to pollution and describes the advantages of estimating of the degree of environmental pollution. The aim was, to find out whether the degree of pollution conforms to the contents of the investigated elements in leaves, the assessment of variability of morphometric leaf traits and the cationic equilibrium values. The study has shown a statistically significant differentiation between the analysed sites in respect of dust fall, concentrations of elements in soils and leaves, morphometric traits of leaves and the cationic equilibrium. The hierarchical tree plot of cluster analysis qualified the sites as polluted and non-polluted. In polluted sites the contents of metals in leaves were significantly higher and the cationic equilibrium in leaves was disturbed. The surface, width and asymmetry of leaves, and also the variability of these measures were higher in polluted sites. In sites, which are not directly affected by pollution the cationic equilibrium is close to the const. value, whereas leaf traits have shown the lowest values and a considerably lower variability. The investigations show that leaf traits and cationic equilibrium correspond to the level of pollution and can be used as a tool for evaluation of the environment status.

    Opis:
    There is increasing number of trees dying in large urban agglomerations. The problem is mostly pronounced in the case of street trees. In Polish cities, apart of pollutions generated by traffic, an important factor that causes death of trees is high salt concentration as a result of winter salt application for de-icing of streets. The aim of the study was to assess the growth of limes (Tilia cordata) planted along highly trafficked Warsaw street and exposed, among others, to salt in a form of saline aerosol. The assessment of shoot length, tree height and crown volume, based on the photographic method of the three increment assessments, showed very restrained growth of the studied limes. In the years 2006-2008 the trees performed so poorly as in similar period of 2003-2005 and grew worse than limes form natural habitats. In 2009 we even observed decrease in size of street trees as compared to 2008 which suggests both very bad condition of street habitats and the studied trees. Salt concentration measured on the surface of tree buds and shoots (EC) was higher in street trees than in trees from natural habitats, which indicates that saline aerosol is the source of sodium chloride. We observed highly diversified reactions of individual trees to the whole complex of street conditions. It is therefore recommended to select for propagation individuals from among most tolerant and vigorously growing plants (genotypes) to be used in street planting.
