Old avenues, or alleys of trees, form an important part of the cultural landscape. They used to be planted mainly in gardens and parks; later, they started playing an even more important role, particularly in the open areas, and within urban landscapes. Nowadays, they are frequently regarded as inconvenient formations, which exert a negative impact on traffic and impede road construction. However, it is is worth bearing in mind that avenues play a number of crucial functions in terms of climate, ecology and aesthetics, and as such they deserve particular care. The article is devoted to the linden trees planted in an avenue layout along the Nałęczowska street in Lublin town in Poland. The layout currently consists of 85 individual trees in varying health condition, that is, 35% of healthy trees, nearly half exhibiting signs of reduced vitality, and 16% in the state of advanced decay.

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

Inonotus rickii (Pat.) Reid is a pathogenic wood-decaying fungus that causes severe decay in several ornamental urban trees in Europe. It has been known to occur on different hosts in Sicily (Italy) since 1985, and in Rome (Italy) since 2003. Some physical and mechanical wood features were studied according to the standards in order to propose an investigation methodology to set a deterioration ranking of urban trees. In this phase of the study, Celtis australis L., Acer negundo L., Acer campestre L., Robinia pseudoacacia L., Tilia × vulgaris Hayne, Ulmus minor Mill., Platanus × acerifolia (Aiton) Willd. and Quercus ilex L. were studied. The data were analyzed using ANOVA and M-ANOVA tests to check the differences among the specimens. A risk matrix was created in order to combine the features that showed statistical differences between the control specimens and the inoculated specimens, in order to establish, in vitro, a degradation ranking among the wood species. The wood species which showed no in vitro durability to I. rickii, were the same ones that displayed susceptibility in the living trees.

Urban environments create unfavourable conditions for tree growth, particularly for street trees, thus, the selection of tree species to severe growth conditions tolerance is of high importance. In our research, the chlorophyll a fluorescence technique was applied to monitor the physiological state of young trees of 8 species and cultivars growing in a street environment in Warsaw. Trees growing 2-3 m away from a road were compared to others growing minimum 8 meters away. Most of the measured parameters concerning photosynthesis, i.e. F0 and FV/FM revealed satisfying values in Acer campestre, Gleditsia triacanthos, Platanus x hispanica cv. Acerifolia and Pyrus calleryana cv. Chanticleer and close proximity to a road had no negative effect on the photosynthetic apparatus. Roadside trees of Ginkgo biloba, Tilia cordata cv. Greenspire and Tilia x europaea cv. Pallida often revealed higher F0 values and lower FV/FM values than the control trees. The results allowed us to distinguish the tolerant species growing under harsh streetside environmental conditions. The chlorophyll a fluorescence technique was found to be a convenient and rapid method for application in in situ experiments.

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.

The paper examines the influence of industrial emissions of sulphur (IV) and nitrogen (IV) oxides on the percentage of stem anatomical characteristics of the autochthonous woody plant species undergrowth of Acer platanoides L. and Fraxinus excelsior L. in the southern industrial zone of the city of Dnipro (Ukraine). It is ascertained, that the ratio of the primary cortex share to the central cylinder share does not change in the stems of annual shoots of the both studied woody plant species when they are exposed to the influence of the toxic gases. However, there are significant changes in the ratio of shares of histological elements in the undergrowth stems of F. excelsior. The use of both absolute and relevant values of anatomic parameters of the plant vegetative organs is needed to analyse the woody plants resistance to technogenic pollution of the environment.
