Opis:
A Scots pine forest, affected by the great cormorant colony, was studied by plot-based fungal survey method during the years 2010-2012 in Lithuania. Diversity and composition of fungal communities were investigated at five zones that had been influenced by different stages of breeding colony establishment: starting-point and almost abandoned cormorant colony part (zones A and B), active part (zones C and D), and the edge of the colony (zone E). The control zone G in undamaged by cormorants pine stand was assessed too. A total of 257 fungal species of ascomycetes including anamorphic fungi, basidiomycetes and zygomycetes were recorded. Seven species were registered for the first time in Lithuania. Species richness in the examined zones varied, lowest being in zones B (51 species), C (46) and D (73) and almost twice as high in the zones A and E (129 and 120, respectively). The comparison of fungal species compositions of different zones showed that their similarity was rather low (SS: 0.22–0.59). The most obvious changes in the trophic structure of fungal communities in the territory occupied by the bird colony were a strong decrease of mycorrhizal species, the presence of coprophilous fungi on forest litter, and the appearance of host-specialized fungi on alien and non-forest plants that have established in the disturbed forest.

Opis:
The aim of the research described in this paper is to classify groundwater level patterns in pine stands of forest fresh sites. The approach has been employed with the view to facilitate explaining interactions between physiographic characteristics and groundwater dynamics in prospective research. The methods which have been employed so far for explanation of groundwater level dynamics interactions with local physiographic conditions do not let to draw firm conclusions. The classification of groundwater dynamics patterns requires employing more sophisticated methods, because of a relatively extensive range of groundwater dynamics site-to-site variability expressed, e.g., by amplitude and cycle period. The methods of groundwater patterns classification proposed in the literature focused either on hydrogeological criteria or, if related to forest ecosystems, focused on water balance elements in forest habitats. The area selected for investigation represented typical features for the Northern European Lowland forests defined by soil and form of terrain pattern shaped by the last glacial period (Vistulian glaciation) and dominant share of Scots Pine (Pinus sylvestris L.) in stand species composition. The research period covered the 2002-2007 hydrological years. The measurement used in analysis covered 35 sites equipped with measurement wells.

The paper shows differences in morphological and anatomical features of the Scots pine (Pinus sylvestris L.) growing on former agricultural and forest lands. It was found that at the same age and in the same climatic conditions Scots pines from former agricultural land had larger stem dimensions and needle sizes as compared with the trees growing on forest land. These results lead to an interesting conclusion connected with future afforestation and reforestiation in the Krynki Forest District.

Opis:
Ectomycorrhizas of Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.) were sampled in a mature forest ecosystem exposed for more than 40 years to moderate levels of gaseous and dust pollutants. Soil of the forest site was characterised by low pH and accumulation of heavy metals (Pb, Mn, Zn, Cu, Cd, Fe). Mycorrhizal vitality and enzyme activity of the root-surface and soil acid phosphatase (AcPase) were studied at 17 measurement points (0–5 cm soil depth) in relation to the content of inorganic phosphate (Pi) and aluminium ions (Al3+) in the soil. Anatomy of Scots pine and beech mycorrhizas taken from different measurement points was observed. The concentration of essential nutrients (C, N, P, Ca, Mg) and the ratios Ca/Al, Mg/Al and N/P were analysed in fine roots. High concentrations of Al3+ in the soil (40–118 meq kg-1) and low levels of Pi (12–44 mg P2O5 kg-1) were accompanied by high activity of the root-surface AcPase of pine and beech mycorrhizas (25–67 and 33–86 μmol pNP g-1 fresh weight h-1, respectively) and soil AcPase (6.8–22.4 μmol pNP g-1 dry weight h-1). The results indicate that fine tree roots are undoubtedly under stress as evidenced by a disturbance in P uptake and accumulation. However, the high vitality of mycorrhizas and the high Ca/Al ratio in fine roots suggest that the defence mechanisms of mycorrhizas and the rhizosphere are still able to ameliorate the influence of anthropogenic pollution.
Badania ektomikoryz sosny (Pinus sylvestris L.) i buka( Fagus sylvatica L.) prowadzono na Pogórzu Karpackim w dorosłym drzewostanie, który przez ponad 40 lat znajdował się pod wpływem gazowych i pyłowych zanieczyszczeń powietrza o średnich stężeniach. Gleby badanego ekosystemu leśnego cechowało niskie pH oraz znaczna akumulacja metali ciężkich (Pb, Mn, Zn, Cu, Cd, Fe). Badano zależność między stężeniem nieorganicznego fosforanu w glebie, a aktywnością enzymatyczną kwaśnej fosfatazy mikoryz i gleby. Analizowano także stężenia pierwiastków odżywczych (C, N, P, Ca, Mg) oraz jonów glinu (Al3+) w korzeniach drobnych. Mikoryzy sosny i buka były analizowane pod względem budowy anatomicznej oraz żywotności. Stwierdzono stosunkowo wysokie stężenie jonów Al3+ w glebie (40–118 meq kg-1) i niski poziom nieorganicznego fosforanu (Pi) (12–44 mg P2O5 kg-1). Jednocześnie zarejestrowano wysoką aktywność powierzchniowej kwaśnej fosfatazy mikoryz sosny i buka(odpowiednio, 25–67 i 33–86 μmoli pNP g-1 świeżej masy h-1) oraz kwaśnej fosfatazy gleby (6,8–22,4 μmoli pNP g-1 suchej masy h-1). Stężeniafosforu w korzeniach drobnych (poniżej stężeń uważanych za optymalne) oraz wysoki stosunek N/P pokazują, że pobieranie i akumulację fosforu przez systemy korzeni drobnych sosny i bukajest niedostateczne, mimo wysokiej aktywności kwaśnej fosfatazy. Budowa anatomiczna mikoryz, stosunkowo duży udział żywych mikoryz w systemie korzeni drobnych oraz wysoki stosunek Ca/Al w korzeniach sosny i buka(odpowiednio, 1,79 i 2,38) sugerują, że mechanizmy obronne mikoryz i mikroorganizmów ryzosfery mają zdolność łagodzenia wpływu zanieczyszczeń antropogenicznych.

Opis:
Mycorrhizal syntheses of pine seedlings were conducted with Suillus luteus (L.) S.F. Gray, a strain No 14 characterised by high tolerance to Al3+ ions and a strain No 62, sensitive to aluminium. The experiment was performed as a semi-sterile culture in a peat-perlite medium with Al3+ ion concentration of 11 mM. Abundant coralloid and cluster mycorrhizas of S. luteus were formed on roots of the inoculated plants at the beginning of the experiment. Aluminium treatment limited mycorrhizal morphotypes to single and dichotomous and significantly reduced the total number of mycorrhizal tips but had no effect on extramatrical mycelium development in the potting substrate. Al treatment did not affect growth of the above-ground part of the tested plants but significantly reduced root growth of mycorrhizal seedlings. The effect of Al on the internal nutrient status was variable and not very much pronounced. A considerable amount of Al was absorbed by the roots and translocated to the shoots. Mycorrhiza formation with both strains of S. luteus did not prevent Al3+ translocation to the upper parts of the tested seedlings. The results suggest that low pH and high Al availability may harmfully influence mycorrhizal symbiosis of Scots pine (Pinus sylvestris L.) by anega tive effect on fine-root production and fewer short root tips available for colonisation rather than through a direct negative effect of Al3+ ion concentrations on extramatrical mycelium in the soil.
Syntezę mikoryzową siewek sosny (Pinus sylvestris) z odpornym naglin szczepem Suillus luteus nr 14 i wrażliwym na glin szczepem nr 62 przeprowadzono w warunkach półsterylnych w szklarni. Po nawiązaniu mikoryzy siewki przez 6 miesięcy traktowano roztworem glinu o stężeniu 11 mM przy pH = 3,8. W warunkach kontrolnych (bez glinu) oba szczepy S. luteus tworzyły obfite mikoryzy pojedyncze oraz dichotomicznie i koralowato rozgałęzione. Traktowanie glinem zredukowało morfotypy mikoryzowe do pojedynczych i dichotomicznych oraz znacząco zmniejszyło całkowitą liczbę wierzchołków mikoryzowych na korzeniach siewek, ale nie ograniczyło rozwoju grzybni ekstramatrykalnej. Wwarunkach kontrolnych (bez glinu) rozwój grzybni ekstramatrykalnej, mierzony zawartością ergosterolu w podłożu był podobny w przypadku obu testowanych szczepów. Traktowanie glinem spowodowało pewien wzrost rozwoju grzybni ekstramatrykalnej szczepu tolerancyjnego i nieznaczne zahamowanie wzrostu szczepu wrażliwego. Glin ograniczył znacząco wzrost korzeni, natomiast nie stwierdzono negatywnego wpływu glinu na wzrost części nadziemnych siewek. Siewki traktowane glinem absorbowały w korzeniach znaczne ilości tego metalu, który był także przemieszczany do pędów. Stwierdzono niewielki wpływ glinu na zawartość pierwiastków mineralnych w siewkach. Badania wykazały, że przy zastosowanym wysokim stężeniu glinu szczep Nr 14 wyselekcjonowany w warunkach in vitro jako odporny na glin, nie zahamował przemieszczania jonów Al3+ do części nadziemnych siewek sosny. Wyniki sugerują, że szkodliwe działanie jonów glinu na symbiozę mikoryzową w warunkach niskiego pH polegara czej naogra niczeniu liczby wierzchołków korzeni drobnych, które potencjalnie mogą tworzyć mikoryzy, niż nabezpośrednim wpływie na grzybnię mikoryzową.

Opis:
A lichenological inventory was conducted in the pine stands in the south-eastern region of Żerków-Czeszewo Landscape Park. The aim of this study was to recognize the lichen species diversity on the bark of Pinus sylvestris by considering tree age and forest habitat type. In total, 26 species of lichenized fungi were found on the bark of P. sylvestris. The biota comprises common and widespread species in Poland. Tree age positively and significantly influenced the species richness on the bark of P. sylvestris. The suitability of the pine tree age for lichens evident as alpha diversity seemed to be independent from the habitat of the trees. The age of phorophytes strongly affected the presence of Hypocenomyce scalaris. Mixed fresh coniferous forests were characterized by higher beta- and gamma diversity compared to fresh coniferous forests. There was no correlation between the number of species per tree (alpha diversity) and diversification of species composition in relation to the distance between pines. The findings indicate that maintenance of a variety of phorophytes and age-diversified tree stands can prevent impoverishment of the lichen biota in the south-eastern part of Żerków-Czeszewo Landscape Park.

Opis:
Provenance trials with forest trees provide valuable information about growth and adaptability of populations often transferred over large geographical and climatic distances. In this study we evaluated growth and survival of 19 Scots pine (Pinus sylvestris L.) populations representing most of the natural range of the species in Europe, growing in a 30-year-old provenance trial in the northeastern Poland. We used cluster analysis to investigate differentiation among those populations in growth and survival. We also used published data on needle morphology and allozyme and DNA marker variation for those same populations to compare groupings of populations based on growth and needle traits and markers. We found significant variation among tested populations in all investigated traits – the largest variation was found for stand volume which integrates information on growth and survival. Variation in growth traits was related to the latitude of population origin with populations from the latitudinal band between 49° N and 54° N showing the best performance. Populations originating from both north and south off of that region showed lower productivity, which for southern provenances resulted from their particularly low survival, reflecting the lack of adaptation to the environment of the research site. Grouping of populations based on growth traits revealed three clusters corresponding to the three latitudinal regions – northern, central and southern. Needle morphological traits were not appropriate as markers of productivity. Clustering of populations based on needle morphology, and especially based on biochemical and molecular markers, did not correspond to the grouping based on growth traits.

Opis:
DNA amplification was investigated in order to determine fungal species present in the Koronevka forest nursery (eastern part of Belarus). For this purpose, needles and roots of Scots pine (Pinus sylvestris L.) seedlings as well as soil collected around roots were examined for ITS1– 5.8S RNA-ITS2 region sequences and compared with GenBank data. DNA analysis of seedlings microflora and soil samples allowed identification of twelve different species of fungi. Among these Cladosporium herbarum Link, Davidiella tassiana Crous and U. Braun, Alternaria alternata Nees and Cryptococcus pinus Vuill. were often found in symptomatic needles. Pathogenic fungal species were detected in 57% of shrunken needles. Examination of DNA extracted from seedling roots revealed occurrence of Wilcoxina mikolae Chin S. Yang and Korf, C. herbarum, and A. alternata. In soil samples there were identified fungi of the same species, with predominance of mycorrhizal fungus W. mikolae (in 100% of samples) and C. pinus (in 20% of samples). The results demonstrated usefulness of molecular markers for the detection and identification of fungi.

Opis:
To evaluate the geographic variability of Pinus sylvestris populations seven morphological traits of needles of pines from IUFRO 1982 provenance trial have been analyzed. The studied populations originated from northern (>55°N in Russia, Sweden and Latvia), central (55-47°N in Poland, Germany, Belgium, France, Slovakia) andsouthern (<47°N in Hungary, Bosnia, Montenegro andTurkey) European ranges of Scots pine. The analyzedprovenance trial experimental areas were locatedin Kórnik (western Poland) andin Supraśl (north-eastern Poland). The greatest variation was found in needle length and number of stomata rows on the flat and convex side of a needle, whereas number of stomata per 2mmof needle length on flat and convex side of a needle was stable, with minor interpopulational variation. Biometrical analyses revealed a significant population × location interaction anda geographical pattern in interpopulational differentiation in both experimental sites, with the northern andsouthern European Scots pine groups of provenancesdiffering significantly from the group of central origin. The results obtainedare compatible with previous results of studies on provenance variability of the Scots pine from IUFRO 1982. In the light of available data, the influence of the Balkan glacial refugia of Pinus sylvestris on a present genetic diversity of this species in Europe and the reconstruction of Scots pine migration routes after the last glacial period are discussed.

The aim of the study was to determine whether there is a correlation between breast height diameter, tree height and stem total volume of Scots pines, on the one hand, and volume and proportion of juvenile wood, on the other. The investigations comprised pure pine stands of the IInd, IIIrd, IVth and Vth age classes developed in conditions of fresh mixed coniferous forest. A distinct curvilinear correlation was found between volume and proportion of juvenile wood in tree stems and breast height diameter, height and stem total volume. Because of high values of determination coefficients (R2), which characterised the above-mentioned correlations, it seems appropriate to use these regularities to assess the quality of the timber raw material regarding the proportions of its volume and juvenile wood in stems of Scots pine trees.

Opis:
Ectomycorrhizal communities associated with Pinus sylvestris growing on dry coniferous forest habitat after the fire were studied. In order to investigate the fire effect on ectomycorrhizal fungi and changes of soil parameters in the upper (0−15 cm) soil layer three study plots were established: 1 – the control, 2 – fire zone left for artificial renewal (with the economic method of renewal) and 3 – fire zone left for natural renewal. The analysis of mycorrhizae revealed presence of eight mycorrhizal fungi on Scots pine roots and the value of Shannon−Wiener species diversity index H’ equaled to 1.76. The most abundant were mycorrhizae formed by Tomentella feruginea (31.7%) and Hebeloma crustuliniforme (23.3%). The fraction of Paxillus involutus and Rhizopogon sp. mycorrhizae was 16.7% and 13.0%, respectively. The lowest was the number of Thelephora terrestris mycorrhizae (only 1.7%). At the site 2, number of mycorrhizal fungi diminished to five and Shannon−Wiener species diversity index was also lower (1.37). The predominant were mycorrhizae of Cenococcum geophilum (26.7%) and P. involutus (21.7%), whilst the lowest were mycorrhizae of Suillus luteus (1.7%). Although at the third site the number of ectomycorrhizal fungi was the same as on the site 2, the dominance of Thelephora terrestris (66.7%) caused that Shannon−Wiener’s species diversity index was the lowest (1.05). Mycorrhizae of Paxillus involutus and Wilcoxina mikolae were characterised by similar abundance (13.3% and 11.7%, respectively). The lowest number of mycorrhizae was observed for Tomentella sp. (3.3%). Analysis of soil parameters showed an increase of pH on burnt sites in comparison to the control. The soil of burnt sites were also characterised by lower value of C and C/N ratio than the soil on the control treatment. The result showed that ubiquitous mycorrhizal fungi, such as T. terrestis, are able to persist on roots in changed soil environment with low content of nutritions.
