Opis:
The abundance and diversity of wood decomposing fungi were investigated by isolating and cultivating filamentous fungi from wood and by detection of fruit bodies of ascomycetous and basidiomycetous fungi. The objective was to study the impact of forest management on fungi in 100-year-old oak and 87-year-old Scots pine forests in Northern Poland. Fungi were found on coarse woody debris of decayed stumps and fallen logs, boughs and branches in each of the three (managed and unmanaged) examined stands. In total, 226 species of Oomycota and fungi were recorded. Oak wood was colonized by one species of Oomycota and 141 species of fungi including Zygomycota (19 species), Ascomycota (103 species) and Basidiomycota (19 species). Scots pine wood was also colonized by one species of Oomycota and 138 species of fungi including Zygomycota (19 species), Ascomycota (90 species) and Basidiomycota (29 species). In the first, second and third stages of decomposition, the oak wood was colonized by 101, 89 and 56 species of fungi respectively and pine wood was colonized by 82, 103 and 47 species respectively. Eighty three of the observed species (37%) occurred on both types of wood, while the other species displayed nutritional preferences. A decrease in the number of species with advancing decay indicates the necessity for a continuous supply of dead wood to the forest ecosystem. This supply would secure the continuity of fauna and flora and guarantee a stable forest development. The nutritional and ecological preferences of many fungal species furthermore indicate the necessity of supplying the forests with wood of different species. In commercially managed forests the results obtained here will aid in: (i) the development of strategies for effective dead wood management in the context of forest productivity and future wood stock growth, as well as (ii) finding a compromise between forest management requirements and environmental protection.

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 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:
On the basis of literature data and own research, algorithms for the calculation of the amount of released CO2 and C per hectare per year were developed taking into consideration 1) the share of trees infected by root pathogens in 80−year−old pine stands, 2) the weight of tree roots, 3) the share of cellulose in the wood of roots and 4) the loss of cellulose degraded by fungi. The developed model after transformations contains only a) the merchantable timber volume of trees per hectare to be harvested based on measurements or SILP database and b) the area of occurrence of fungi causing wood decay in roots and stumps (here: Heterobasidion spp., Armillaria spp. and Phlebiopsis gigantea). These data can also provide estimates of the level of carbon sequestration in the non−infested forest stands.

Opis:
The aim of this preliminary study was to assess the activity of laccase, diverse peroxidases as well as the level of micromolecular compounds in Heterobasidion parviporum isolates grown on pieces of Norway spruce wood (sapwood and heartwood) during 50 days of incubation under the laboratory conditions. H. parviporum isolates secreted extracellular enzymes: laccase, manganese peroxidase (MnP), lignin peroxidase (LiP) and versatile peroxidase (VP). Hydroxy− and methoxyphenols were also released during this process. The above−mentioned enzymes showed low activity in mycelium grown on both sapwood and heartwood. The activity of laccase ranged from 0 to 0.513 mU/mg protein on sapwood, and from 0 to 0.106 mU/mg protein – on heartwood. MnP activity of H. parviporum isolates ranged from 0.024 to 0.667 mU/mg protein on sapwood, and from 0.038 to 1.585 mU/mg protein – on heartwood. LiP activity was small and ranged from 0 to 1.281 mU/mg protein on sapwood, and from 0.013 to 0.166 mU/mg protein – on heartwood. Activity of VP oxidizing manganese ions was low. It ranged from 0 to 3.063 mU/mg protein on sapwood, and from 0.059 to 3.054 mU/mg protein – on heartwood. The activity of VP oxidizing guaiacol ranged from 0.006 to 1.490 mU/mg protein on sapwood and from 0.038 to 1.147 mU/mg protein – on heartwood. The hydroxyphenols produced by H. parviporum isolates ranged from 15.037 to 110.149 mg of protocatechuic acid/ml on sapwood, and from 11.236 to 27.220 mg of protocatechuic acid/ml – on heartwood. Methoxyphenols produced by H. parviporum isolates ranged from 3.393 to 24.253 mg of vanillic acid/ml on sapwood, and from 4.955 to 12.005 mg of vanillic acid/ml – on heartwood.

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.
