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:
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:
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 first seed orchards of lime trees Tilia cordata Mill. were established in Poland in the Susz Forest district in 1985. Currently, there are 21 seed orchards of this species in the country in order to satisfy the seed demand and preserve the species as well as genetic diversity. due to disease symptoms occurring on Tilia trees and irregular fruiting, an attempt was made to collect information on the problems of seed orchards and their characteristics in Poland. In order to achieve this goal, the average annual seed yield and the total amount of seeds collected in plantations located in Poland were analyzed and compared. each of the selected plantations currently has several dozen different Tilia clones, which mainly serve to preserve the genetic diversity. these orchards are producing seeds from which new tree seedlings are grown and therefore increases in yield are desired. In this study, we analysed orchard location and their seed yield based on the information provided by Forest districts and the National Seed register, in which foresters record data on the collection of seeds as well as breeding difficulties resulting from unsuitable soil types. we were able to determine that the seed yield is primarily influenced by the age of the trees. In addition, trees are exposed to changing weather conditions each year, which may not always be conducive to seed formation. Furthermore, it is during seed collection that disease symptoms or nutritional deficiencies of trees are noticed and recorded, which may not occur every year due to variability in seed formation and demand. In addition, trees are exposed to changing weather conditions each year, which may not be conducive to seed formation.

Opis:
Road traffic emits a cocktail of pollutants that can influence the vegetation and plant diversity in neighboring areas. However, the recovery potential of bryophytes after traffic abandonment is still little explored. In addition, the effects of the main pollutants of road verges, such as metals and salinity, on moss flora need to be investigated. In our study, we compared the moss richness and diversity in two closely related veteran tree allees of high conservation importance. The allees in Gryżów and Lubrza, Poland, were chosen because of their similarity in age, geographical location, type of surrounding areas, and tree species. The only difference was that the trees in Gryżów had not been exposed to direct road pollution for almost 30 years. The moss richness and diversity differed significantly between the sites. Altogether, 20 moss species were recorded on 229 trees, 17 species in Gryżów (abandoned road), and 13 in Lubrza (busy road). We found considerable differences between moss cover on the road-facing and opposite sides of tree trunks. In Lubrza, mosses on the road-facing side were very scarce. The moss cover in Gryżów was highly balanced between trunk sides as well as among trunk heights. Typical epiphytic species such as Bryum moravicum, Dicranoweisia cirrata, Leskea polycarpa, and Orthodicranum tauricum preferred the Gryżów tree stands, where they were present in numbers almost twice as high as that at Lubrza. The study shows that constructing a bypass road could be an effective conservation measure for veteran tree protection with their epiphytic moss flora.

Opis:
W wyniku szczegółowych obserwacji stanu zachowania roślin drzewiastych (klonu pospolitego (Acer platanoides), klonu jaworu (Acer pseudoplatanus), jesionu wyniosłego (Fraxinus excelsior) oraz lip (Tilia cordata, T. x europaea) w pasach drogowych Krakowa stwierdzono masowe występowanie u większości badanych drzew podobnych objawów uszkodzeń, w postaci nekrotycznego zbrunatnienia blaszek liściowych, obejmującego 10-80% powierzchni blaszki oraz przedwczesnego opadania liści, niezależnie od rodzaju i gatunku. Ponadto obserwowano zamieranie pędów, zwłaszcza w środkowej części koron. Susz obejmował niejednokrotnie 80-90% konarów i gałęzi. Często w miejsce przedwcześnie opadłych liści rozwijały się nowe, jasnozielone, o zredukowanej powierzchni blaszki. Analiza fitopatologiczna i entomologiczna badanych próbek drzew wykluczyła działanie organizmów żywych. Wyniki pomiarów próbek gleb, pobranych spod chorych drzew, wykazały nadmierne jej zasolenie - od 0,5 do 0,8 mS·cm⁻¹. Stwierdzono również występowanie podwyższonego alkalicznego odczynu podłoża, przyjmującego wartość w zakresie pH 8-10. Biorąc pod uwagę całokształt wyników obserwacji sugeruje się, że masowe uszkodzenia drzew w pasach przydrożnych centrum Krakowa są spowodowane zniszczeniem gleby jako środowiska wzrostu korzeni drzew, w szczególności nadmiernym jej zasoleniem i alkalizacją.
As a result of the thorough observation of the performance of tree plants (Acer platanoides, Acer pseudoplatanus, Fraxinus excelsior and Tilia cordata, T. x europaea) along the communication routes of Kraków a significant demonstration of similar damage was detected. In particular, it took the forms of necrotic browning of leaves, this effect concerned from 10 to 80 % of the leaves or the premature falling of leaves regardless of the genus or species. In addition dying of branches was observed, in particular in the middle part of the tree crones. The dryness frequently concerned as much as 80-90% of twigs and branches. Often in the place of fallen leaves new ones were formed, however with a smaller surface of the blade leaf (20-30% decrease of leaf area). The phytopathological and entomological analysis of the examined tree samples excluded an influence of any living organisms. The results of the analysis of the soil samples collected from under the damaged trees showed that it was high salinated, from 0.5 to 0.8 mS·cm⁻¹. It was also determined that there is a higher alkaic pH factor of the ground (about 8-10). Taking into consideration the entire results of the observation it is suggested that the massive damages to the trees along the communication routes of the centre of Kraków are caused by the destruction of soil as a environment of root growth, in particular its excessive salinity and alkalisation.
