Opis:
Within the framework of Project no. POIG.01.03.01-30/074/08 “Ionic liquids in innovative technologies connected with processing of lignocellulosic raw materials” the Wood Based Panels and Glues Department of the Wood Technology Institute in Poznan carried out research aiming at application of ionic liquids in particleboard technology. The objective of the research was application of [DDA][NO3] and [BA][NO3] ionic liquids in preservation technology of panels resistant to biotic factors. The method for application of ionic liquids to particleboards, the type and amount of chosen ionic liquids, as well as their influence on standard parameters of the panels were investigated. In the tests the amine resin available on the domestic market and particles obtained from debarked Scots pine chips were used. The results of the research demonstrated that ionic liquids worsened parameters of the panels, but improved their resistance to decay fungi.
W Zakładzie Materiałów Drewnopochodnych i Klejów w ramach Projektu nr POIG.01.03.01-30/074/08 „Ciecze jonowe w innowacyjnych technologiach związanych z przetwarzaniem surowców lignocelulozowych” realizowane są badania zmierzające do zastosowania cieczy jonowych w technologii płyt wiórowych. Celem badań jest wykorzystanie cieczy jonowych w technologiach zabezpieczania płyt na działanie czynników biotycznych. Dotychczasowe badania obejmowały opracowanie sposobu wprowadzania cieczy do wiórów przeznaczonych do wytwarzania płyt, poznanie wpływu rodzaju i ilości wybranych cieczy jonowych – [DDA]NO3], [BA][NO3] – na standardowe właściwości. Stosowano klejową żywicę aminową dostępną na rynku krajowym i wióry pozyskane z korowanych zrębków sosnowych. Badania wykazały, że zastosowane ciecze jonowe obniżają właściwości mechaniczne płyt, poprawiają natomiast ich odporność na grzyby rozkładu brunatnego.

Opis:
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].

Opis:
Rozkład drewna w przyrodzie wywołany jest głównie przez grzyby „białej zgnilizny” z klasy Basidiomycetes, do których należy Phanerochaete chrysosporium. Celem pracy było zbadanie produkcji enzymów ksylanolitycznych w hodowli P. chrysosporium w pożywce mineralnej Czapeka z dodatkiem słomy lub otrąb pszennych. Wyniki badań wykazały, że P. chrysosporium wytwarza enzymy ksylanolityczne (endo-1,4-β- ksylanazę i β-ksylozydazę) w pożywce hodowlanej z dodatkiem obu substratów. Aktywność endo-1,4-β-ksylanazy i β-ksylozydazy zależy od temperatury i jest najwyższa odpowiednio w 70 i 60oC. Maksymalną aktywność obu enzymów stwierdzono w odczynie kwaśnym, pH = 4,6.
Degradation of wood in nature is caused mainly by white rot fungus representing Basidiomycetes, such as Phanerochaete chrysosporium. The aim of this studies was to investigate the production of xylanolytic enzymes (endo-1,4-β-xylanase and β-xylosydase) by Phanerochaete chrysosporium cultivated on Czapek mineral medium to which straw or wheat bran was added. The results showed that P. chrysosporium produced both enzymes endo-1,4-β-xylanase and β-xylosydase in culture medium with the two substrates added. The activity of endo-1,4-β-xylanase and β-xylosydase depends on temperature and it is highest at 70 and 60oC. The maximum activity of both enzymes was found for the acid reaction, pH = 4.6.

Opis:
The experiment conducted in the Kampinos National Park since 2015 was aimed at assessing the sprouting ability of black cherry (Prunus serotina Ehrh.) in response to different measures of mechanical control and mycobiota colonizing the dying trees. Basal cut-stump, cutting at ca. 1 m above the ground and girdling were performed on 4 terms, two plots and applied to 25 trees, 600 trees in total. Sprouts were removed every 8 weeks since the initial treatment for 4 consecutive growing seasons, except winter-treated trees. At the end of the fourth season of control, 515 out of 600 trees were dead (86%): 81% on Lipków and 90% on Sieraków plot. Among 18 experiment variants with sprouts removal, 17 showed more than 80% of dead trees. The lowest, 76% share, concerned summer cut-stump at the base of the tree. For winter measures, the share of dead trees was lower in all cases and ranged from 28% to 64% proving that sprouts removal contributes to the drop of sprouting strength and quicker dying of the trees. Almost 80% of trees showed sporocarps that represented 51 taxa of macrofungi in total, including 6 Ascomycota and 45 Basidiomycota. The group of six most frequently encountered fungi includes: Hyphoderma setigerum, Bjerkandera adusta, Peniophora cinerea, Armillaria ostoyae, Nectria cinnabarina, Stereum hirsutum. Both plots had similar share of black cherry individuals with sporocarps of macrofungi, that is, 81% and 78% for Sieraków and Lipków respectively. The share of colonized trees and the number of reported macrofungal taxa increased significantly compared to the year following the treatment. In addition, the composition of macrofungi changed with the progressing dying of trees. These results broaden the knowledge about macroscopic fungi colonising and living on black cherry within its secondary range of distribution. Moreover, one macrofungus and two microfungi new for KNP are reported.

Opis:
Changes of physical and chemical properties, mass loss and susceptibility of oak wood to decay caused by Basidiomycetes fungi were assessed after wood samples had been taken out of the sea within the framework of MACHU project. Test samples of oak wood of the dimensions of 250 × 10 × 10 mm were placed in coastal waters of the Baltic Sea at the area of medieval seaport in Puck and in waters of the Gdansk Bay at the same longitude as Orłowo (near the wreck of Swedish warship Solen). The samples taken out of the sea were examined visually and described. Changes in mass of the samples, their bending strength and modulus of elasticity, compression strength along the grain, ability to decay caused by Trametes versicolor fungus, content of mineral substances and substances soluble in water, ethanol-benzene mixture and in 1-percent aqueous solution of NaOH, content of cellulose, lignin and pentosanes as well as pH of the wood were investigated. The properties of samples taken out of the sea after 6 months of immersion were compared with the properties of control twin samples of oak wood which had not been immersed. The results obtained so far indicate that noticeable, measurable changes in oak wood immersed in sea occur already in half a year since immersion, so observation of them may be useful for protection and monitoring of underwater archaeological objects.

Opis:
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.

Opis:
Wood degrading capacity of lignicolous fungi was studied by decay test. In which two methods were followed, i) wood chips method ii) wood block method. Eight timbers infected by six fungi were selected for studying percentage of decay and biochemical test was done to know delignification. After 12 months, 90 % of wood block of T. arjuna was decayed by L. stereoides. In teak wood 16.82 % of decay was due to H. apiaria in 3 months. As the percentage of moisture was less, percentage of weight loss was also less; this indicated that decay capacity of fungi will depends on % moisture content in wood. The percentage loss in hot water soluble substrates was more in case of T. crenulata due to L. stereoides for 5 months, whereas lowest in case of teak wood decayed by H. apiaria for 5 months. The percentage loss in ethanol benzene soluble substrate was more in case of Adina wood decayed by C. versicolor for 5 months, whereas lowest in case of teak wood infected with L. stereoides for 3 months. As the incubation period increases, percentage loss in acid soluble lignin was more in case of infected woods. L. stereoides, C. versicolor, and H. apiaria showed selective delignification in all infected woods, whereas T. pini showed simultaneous degradation of lignin in all woods tested. The valuable timber like teak wood was not resistant to wood decay because they loss 50% of lignin. The in vitro wood decay test can‟t be taken as absolute evidence for wood decay behavior of lignin-degrading fungi, so we should conform decay of wood by consider biochemical test. For rapid evaluation of wood decay the wood chip method was best suitable. For the first time the wood decay and biochemical test of 8 wood samples infected by white rot fungi like S. commune, L. stereoides, H. apiaria, C. versicolor, T. pini and soft rot fungi like T. viride was studied.

Opis:
Globally, tree-holes are important ecological component of forest and woodlands. Numerous microorganisms rely on cavities, both natural and those excavated by primary cavity nesting birds, mainly by woodpeckers, for their survival and reproduction. However, the fungi occurring in cavities are not well characterized. Specifically, very little is known about the fungal communities inhabiting the woodpecker nest cavities. Therefore, in this study, we investigated the fungal diversity of cavities in southern Poland. The samples were collected from freshly excavated woodpecker nest cavities using a nondestructive method (ND). The spatial distribution of fungal communities within the cavities was evaluated by sampling different parts of a single cavity using a destructive method (D). We detected 598 fungal isolates that included 64 species in three phyla and 16 orders using the ND method. Most of the fungi isolated from the cavities represented the phylum Ascomycota (73.9% of the isolates) with 11 orders, and Microascales was the predominant order (30% of the isolates). The most common species detected was Petriella musispora, which was isolated from 65% of the cavities. A total of 150 isolates (25%) were members of Basidiomycota, with Hymenochaetales being the dominant order (16% of the isolates). The basidiomycetous fungi were isolated from 55% of the cavities. Several taxa closely related to the pathogenic fungi and associated with secondary animal infections were detected in the wood of cavities. We identified different fungal communities in the three cavity parts using the D method. The cavity entrance had more number of species than the middle and bottom parts. The results of this study advanced our current knowledge on the mycobiota in woodpecker nest cavities and provided preliminary evidence for tree cavities being the hotspot for fungal diversity.

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.

Evaluation of the fungicidal properties of essential oils from Leptospermum scoparium and Azadirachta indica in relation to selected fungi causing wood decay. The publication presents the results of evaluation of the fungicidal effect of two essential oils from Leptospermum scoparium (manuka) and Azadirachta indica (neem) on fungi that cause the decomposition of Trametes versicolor and Coniophora puteana wood. Research results indicate that the growth of the tested fungi is clearly inhibited with the participation of the highest concentrations of essential oils used. At the same time, it was found that the action of neem oil was stronger compared to the Traetes versicolor fungus. In contrast, manuka essential oil has a stronger inhibitory effect on the growth of Coniophora puteana.

W publikacji przedstawiono wyniki oceny działania fungicydowego dwóch olejków eterycznych z L. scoparium (manuka) i A. indica (neem) na grzyby powodujące rozkład drewna Trametes versicolor i Coniophora puteana. Rezultaty badań wskazują, że wzrost testowanych grzybów jest wyraźnie hamowany przy udziale największych z zastosowanych stężeń badanych substancji chemicznych. Jednocześnie stwierdzono, że działanie olejku neem było mocniejsze w stosounku do grzyba T. versicolor. Z kolei olejek manuka działał silniej inhibujaco na wzrost grzyba C. puteana.

Opis:
Hericium flagellum (Scop.) Pers. is considered a rare, wood-decaying fungus that occurs on coniferous trees, predominantly on silver fir (Abies alba). In this paper, a new locality of H. flagellum in Wielkopolska Voivodship is presented, along with the macro- and micromorphological features of the collected specimens. Basidiomata of H. flagellum were found in November 2016 and 2017 in the “Olbina” nature reserve (ATPOL Dc-97, Kalisz Forest District), located in a continental mixed coniferous forest close to the northern border of the natural range of silver fir. In 2016, H. flagellum was found growing in the hollow of an old stump of silver fir, and in the following year, this fungus was recorded on a fallen log of silver fir. The implications for conservation are briefly presented. Prospects of further development of the basidiomata of H. flagellum in the “Olbina” reserve are also discussed.

Opis:
Species of the genus Ganoderma are an example of some of the most thoroughly studied representatives of Basidiomycota both in terms of chemical composition and biological activity. Among the compounds found in this kind, the therapeutic effect is primarily associated with the polysaccharides that are heteroglycans or β-D-glucans and terpenoids represented mainly by triterpenes. Triterpene compounds have a structure composed of 30 carbon atoms, usually forming a system of five six-membered rings. Characteristic of these structures are functional groups (hydroxyl, carboxyl or ketone) and double bonds. Mycochemical studies have led to the isolation of numerous triterpenes of the lanostane type (ganoderic acids, aldehydes, alcohols, esters), lucidenic acids and others from various species of the Ganoderma genus. The broad spectrum of biological activity determined by triterpene compounds includes anti- tumor, anti-inflammatory, antioxidant, hepatoprotective, antidiabetic, and antiviral effects. This work describes biologically active triterpenes in selected species of the genus Ganoderma: Ganoderma lucidum, Ganoderma applanatum, Ganoderma adspersum, Ganoderma pfeifferi, Ganoderma colossum and others. These species are sources of natural compounds valued for thousands of years in the traditional medicine of the Far East, while ongoing research has confirmed their medicinal properties nowadays.

Opis:
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.
