    Opis:
    The paper describes the results of investigation on the range of trophic abilities and preferences of fungi causing the wood decay of the brown rot pattern. Fomitopsis pinicola, Laetiporus sulphureus, Piptoporus betulinus and Serpula lacrymans fungi were tested. Wooden samples made from wood of 25 different, both European and exotic, tree species were used. They were put on mycelium of every tested fungus. After 30, 60 and 90 days of exposition samples were weighted and the loss of their mass was calculated to compare the differences of wood destroying abilities between examined tree species. The results indicated that the range of trophic abilities in ex situ conditions of tested fungi species was much wider than in nature. All examined fungi were able to decay the wood of more tree species and their trophic preferences occurred to be different as well.

    There are over 100 thousand old trees protected as nature monuments in Poland. Their health condition in many cases is not satisfying and the new methods of their conservancy against pathogenic, wood decaying fungi are necessary to be prepared. In this paper the evaluation of practical usability of some phenolic compounds naturally existing in wood is described. Natural chemical substances as eugenol, isoeugenol, resorcinol, pyrogallol and 2−furaldehyde (furanone) seem to be very useful in this matter. Artificially applied directly into the stem of living tree by hydrostatic injection, they are able to protect it from the inside as well as commonly used synthetic fungicides, being also less dangerous for the natural environment.

    Opis:
    Black cherry is an important invasive species in forest ecosystems in Poland. It developed mainly in Scots pine stands. The aim of the study was to identify microscopic fungi colonies inhabiting black cherry stumps. In the spring of 2017, wood samples were collected from stumps created after cutting in each subsequent month of 2016 in the Podanin Forest District (19°28'00'E, 52°04'00'N). Stumps up to 5 cm and more than 5 cm in diameter were selected for the study. In total, 72 discs from the first stage of the decomposition of wood were collected. The discs were drilled to obtain fine sawdust for further analysis. The trials were divided into four periods. DNA isolation was performed using the Plant Genomic DNA purification kit (ThermoScientific). The ITS1/2 rDNA region was used for species identification. The analysis was carried out using specific primers. The obtained product was purified and sequenced using the Illumina SBS technology. The resulting sequence was compared using the BLAST algorithm with reference sequences from the NCBI database. The communities of fungi inhabiting the black cherry stumps differed from each other. The highest number of taxa was identified in samples from stumps over 5 cm sheared in autumn and winter, while the lowest in stumps up to 5 cm sheared in spring and winter. Fungi belonging to the Ascomycota and Basidiomycota, Blastocladiomycota, Glomeromycota, Zygomycota and non−cultivable fungi and organisms belonging to other kingdoms were identified. Saprophytes from Menispora sp. dominated on the analysed stumps. The collection of fungi of larger stumps was more diverse and more numerous than on stumps with a smaller diameter. A greater diversity of taxa was distinguished by the stumps of tree fallen in the growing season. The majority of the analyzed samples were dominated by Ascomycota. Basidiomycota clusters dominated in the winter. The predominant share of saprotrophs shows the distribution of stumps. The most desirable effect of the research would be the indication of naturally occurring saprotroph, whose operation would reduce the black cherry’s yield strength. The applied method of sequencing based on the Illumina System was effective to determine the composition of the fungal population.

    Paper presents results of laboratory experiments on the usability of selected phenolic compounds naturally existing in wood for artificial wood protection against wood decay caused by fungi. Some of these substances are believed to work as inhibitors of mycelium’s growths and prevent wood against biological destruction. Six different phenolic compounds were tested individually or mixed together. Lime wood samples were artificially saturated by their water solutions using vacuum methods. Then they were put on the mycelium of Laetiporus sulphureus and Trametes versicolor. The samples were taken out after 30, 60 and 90 days. The loss of their weight was compared with control samples saturated only by water. The differences between these results allowed to improve the potential ability of particular natural compounds for artificial wood protection against biological decay.

    The paper reports the laboratory research on the natural wood resistance against white pattern fungal wood decomposition. Wood samples of 25, both European and exotic, tree species were collected and used (tab. 1). All samples were dried and weighted, then put on the mycelium of four different white rot causing fungi species: Fomes fomentarius ((L.: Fr.) Kickx), Schizophyllum commune (Fr.: Fr.), Stereum hirsutum ((Willd.: Fr.) Gray) and Trametes versicolor ((L.: Fr.) Pilát). After 30, 60 and 90 days of exposition the samples were put out, cleaned, dried and weighted again. The weight loss indicated the range of wood decomposition and allowed to estimate its natural resistance against fungal wood decay. The results showed that in laboratory conditions the range of all fungi species trophic abilities were much wider than the one observed in nature. Examined fungi were able to destroy wood from trees they never occur on. The reasons of this could be both mechanical (the absence of bark – natural barrier for fungi) and chemical (the less of chemical substances occurring in wood of living trees that could be responsible for its natural resistance against fungi).

    Opis:
    Black alder is an important forest−forming species in Poland. Its wood is decomposed by many species of fungi. Ganoderma lucidum (Curtis) P. Karst. is a species of Basidiomycetes which belongs to family Ganodermataceae, order Polyporales. This fungus causes white rot decay of wood in dead and sometimes living alder trees. G. lucidum has been under partial protection in Poland since 2014. It is also red−listed as a rare species (category R – taxa with small populations) on the ‘Red list of the macrofungi in Poland’. The fungus was cut out with a sizeable fragment of wood from the alder stump in Łuków Forest District (eastern Poland) and transported to the laboratory of the Department of Mycology and Forest Phytopathology, Warsaw University of Life Sciences−SGGW. Pure culture of G. lucidum mycelium was obtained from a fragment of fruitbody. The aim of this study was to investigate, through laboratory decay tests, the ability of G. lucidum to degrade alder wood. Sterilization of wood samples (30×20×20 mm) consisted of placing the material in an accelerator and irradiating it with high−energy electrons at a dose of 30 kGy at the Institute of Nuclear Chemistry and Technology in Warsaw. On the next day, wood samples were put into 200 ml flasks with mycelium of G. lucidum on agar−wort medium (2 samples per flask). The flasks were placed in a Heraeus BK 600 incubator for 180 days, with a constant temperature of 22°C and humidity of 80 ±5%. Every 30 days 10 flasks were randomly selected, i.e. 20 samples of alder wood from this experiment. After each incubation period the samples were removed from the flasks, cleaned to remove mycelia and dried at a temperature of 105°C until they reached constant weight. By comparing mass of the samples at the start and the end of experiment in an absolutely dry state, the relative wood mass loss was calculated. After exposure times 180 days, the relative weight loss of alder wood as a result of decay by G. lucidum mycelium was on average 10.88%. The rate of the decay was almost constant during the study period. On some alder wood samples structures resembling fruitbodies of G. lucidum were noticed.

    Opis:
    The aim of the study was to characterize the state and dynamics of dead wood resources in the stands of the Świnia Góra strict forest reserve, which was excluded from use for a longer period of time (from 1938/1953), and to compare the results with the state and dynamics of living trees resources. The reserve covers 51 hectares of an upland forest in the Świętokrzyska Forest (central Poland). Data was collected in 2000, 2007 and 2014 on 95 systematically distributed 500 m2 sample plots. The location and dimensions of living trees, standing dead trees (snags, including stumps) and downed trees (logs) on each sample plot were determined and measured. The decay stages of dead wood were estimated using a four−point scale classification. The average volume of dead wood was 198 ±32 m3/ha (43 ±8% of living trees) in 2000 and 138 ±17 m3/ha (24 ±3%) in 2014 (fig. 1). The ratio of the volume of snags to logs decreased from 30 ±5% in 2000 to 24 ±6% in 2014. Silver fir was the dominant species among both living and dead trees (fig. 2). The share of dead wood volume in decay stages 1 and 2 was the highest among snags, while in stages 2 and 3 – among logs. The number of highly decomposed wood increased in the period 2000−2014 (fig. 3). The decay rate of wood calculated over a 7−year period was more rapid for logs (fig. 4). In the period of 14 years, 119 ±23 m3/ha of dead wood underwent a complete decomposition. Volume of trees that died within that period was 59 ±10 m3/ha (fig. 5). The complete decomposition of snags amounted to 64 ±10% and logs to 58 ±5% of the initial dead wood volume. The dead wood resources in the investigated period were not balanced: the amount of decayed wood was larger than the amount of wood replenishing the resources. The lack of this balance was due to the lack of the balance of living trees – dead wood resources were insufficiently replenished by trees that had died during analysed 14 years. The dead wood resources at a level of approximately 200−230 m3/ha might be balanced via their continuous replenishment by newly died trees in the amount close to the current volume increment.

    The objective of the research was to analyse the level of fungal infection of spruce wood in the mature and overmature stands and determine the age of their technical maturity. Trees from seven stands aged 49−137 were examined. Age was found to have a statistically significant effect on the level of infection of trees caused by wood−rotting fungi. A high infection level was also detected in the bark−stripped spruces of the lower storeys of multi−storeyed stands. The obtained results enabled determination of the age at which spruces are considered mature (technical maturity) for felling at 80−90 years.

    Dead wood in the city parks is removed for safety and aesthetic reasons. ‘Polesie Konstantynowskie’ nature reserve (9.8 ha) located in the western part of Łódź is an exception. In this reserve dead wood is left for natural decomposition. So far in this reserve research was conducted on the vascular flora and stand structure only, but the amount of wood was not measured. The aim of this study was to assess the volume of coarse woody material of various types (coarse woody debris, snags), species, size, (dbh and height) and decay classes. The study was carried out in 2010. The volume of coarse woody debris was estimated with a method proposed by Van Wagner [1968]. The criterion of division into five decomposition classes follows Maser et al. [1979].
