    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:
    Tilia cordata is a good source of food attractants for bees. These insects are the primary pollinators of flowers of this species. Nectar is produced in the floral trichomatous nectaries located on a projection of the adaxial, basal part of the sepals. There were two types of non-glandular hairs on the sepals; the first one to prevent the nectar from flowing out beyond the sepal and the other type to protect the nectary itself. The clavate secretory trichomes, forming dense clusters, are composed of a base, stalk, and multicellular head. The secretory cells of the trichome head contain a thick cytoplasm and a large nucleus; they are also characterized by a low degree of vacuolation. Nectar accumulates at the tip of the trichome in the space formed between the cell wall of the head cells and the cuticle. The several-layered subepidermal glandular parenchyma with densely packed cells is provided with vascular bundles containing xylem and phloem. Plastids containing small starch grains were noticed in many cells of the nectariferous tissue, whereas phenolic compounds were found in the adaxial epidermal cells of the sepals. No presence of starch, lipids, or phenolic compounds was found in the cells of the glandular hairs. However, numerous chloroplasts, calcium oxalate crystals and large mucilage cavities occurred in the subglandular tissue.
    Tilia cordata jest dobrym źródłem atraktantów pokarmowych dla pszczół. Owady te są głównymi zapylaczami kwiatów tego gatunku. Nektar wytwarzany jest w trichomowych nektarnikach kwiatowych zlokalizowanych na uwypukleniu nasadowej części dziłek kielicha. Na działkach kielicha o łódeczkowatym kształcie występują dwa rodzaje włosków mechanicznych: osłaniające nektarniki i zapobiegające wypłływaniu nektaru. Maczugowate włoski sekrecyjne tworzące gęste skupienia są zbudowane z podstawy, trzonka i wielokomórkowej główki. Komórki wydzielnicze główki trichomów zawierają gęstą cytoplazmę i duże jądro komórkowe oraz charakteryzują się słabym stopniem wakuolizacji. Nektar gromadzi się na szczycie w łoska, w przestrzeni tworzącej się między ścianą komórkową komórek główki a kutykulą. Kilkuwarstwowa, podepidermalna parenchyma gruczołowa o zwartym ułżoeniu komórek zaopatrzona jest w wiązki przewodzące, które zawierają drewno i łyko. W wielu komórkach tej tkanki zaobserwowano plastydy zawierające drobne ziarna skrobi, natomiast w komórkach epidermy adaksialnej działek kielicha występowały związki fenolowe. W komórkach trichomów gruczołowych nie stwierdzono obecności skrobi, lipidów oraz związków fenolowych. Natomiast w tkance podgruczołowej występowały liczne chloroplasty, kryształy szczawianu wapnia oraz komory śluzowe.

    Opis:
    The aim of this study was to assess the current state of small-leaved lime stands under climate change, as well as to identify optimal conditions for the occurrence and further growth of natural lime regeneration under the stand canopy to grow productive and sustainable mixed stands. The areas of small-leaved lime (Tilia cordata Mill.) stands in plain Ukrainian forests and mixed stands with English oak (Quercus robur L.) were defined according to reference materials (as of 2016). Growth and liveability peculiarities of natural regeneration of lime under the canopy of oak-lime stands in climate change were identified. The main stand characteristics contributing to maximal appearance and further development of advance growth of lime, such as composition, age and relative density of stocking, were determined. It was found that the lime stands of vegetative origin occupy the largest part of the lime forests’ area, being less resilient and productive than those originated from seeds. Small-leaved lime is the best associated species in mixed oak stands. The presence of lime improves health, assortment composition, and productivity of oak stands and increases their resistance against pests and diseases. In the future, lime can play an important role in the adaptation of forests to climate change due to its biological and forest properties and adaptability to a sustainable existence in a relatively wide range of environmental conditions. A summary of the studies complements a system of knowledge about the current state of lime stands as well as peculiarities of their regeneration and growth. The data obtained can be used as a theoretical base for forest management to promote natural regeneration and maintain the sustainability of these forests.

    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:
    Heavily urbanised areas are not a favourable habitat for plant growth and development. On the other hand, urbanised areas can be a favourable habitat for harmful fauna. Tin our study, those trees growing along the roadside were more heavily infested by pests than trees growing in parks. Three orders of insects, mites and lugs were identified on the Norway maple. The dominant insect species was Periphyllus aceris. On small-leaved lime four insect orders (the dominant species was and Eucallipterus tiliae) and mites were found. An overall visual inspection confirmed that of maple and lime growing in city parks were in better condition than those growing by roads.

    Analyses concerned the effect of different environmental variables on the health status of little-leaf linden (Tilia cordata Mill.). The study comprised analyses and statistical models based on discriminatory analysis. These analyses indicated which variables may influence the health status of tress of the investigated species in the parks of Poznan. The model was based on the canonical variate analysis (CVA), ie Fisher’s canonical variant of linear discriminatory analysis (LDA). The greatest negative effect on the health status of trees of Tilia cordata Mill. in Poznan parks was found for the small distance of the parks from the city centre and the immediate vicinity of two arterial roads. It was also found that the vicinity of buildings heated with fossil fuels, primarily coal, may have had a negative effect on the health status of Tilia cordata Mill. trees in the Poznan parks. Moreover, it was shown that specimens of the investigated species aged 81–120 years were characterised by the worst health status, while the best health condition was found in trees of Tilia cordata Mill. in the Millennium Park.
    Badania dotyczyły wpływu różnych zmiennych środowiskowych na stan zdrowotny lipy drobnolistnej (Tilia cordata Mill.). W pracy wykorzystano analizy i modele statystyczne stworzone w oparciu o analizę dyskryminacyjną. Wynikiem przeprowadzonych analiz było wykazanie, które zmienne mogą wpływać na stan zdrowotny drzew badanego gatunku na terenie parków Poznania. Do skonstruowania modelu wykorzystano analizę CVA (canonical variate analysis) – kanoniczną odmianę liniowej analizy dyskryminacyjnej Fishera (LDA). Stwierdzono, że największy negatywny wpływ na stan zdrowotny drzew Tilia cordata Mill. w parkach Poznania miała niewielka odległość parków od centrum miasta oraz bezpośrednia bliskość dwóch arterii komunikacyjnych. Stwierdzono również, że bliskość zabudowań ogrzewanych paliwami kopalnymi, przede wszystkim węglem kamiennym, mogły wpływać negatywnie na stan zdrowotny drzew Tilia cordata Mill. na terenie parków Poznania. Wykazano również, że osobniki drzew badanego gatunku z przedziału wiekowego 81–120 lat charakteryzowały się najgorszym stanem zdrowotnym, a najlepszą zdrowotność drzew Tilia cordata Mill. stwierdzono w Parku Tysiąclecia Państwa Polskiego.

    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:
    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.
