Opis:
Oak and lime trees constitute nearly 2/3 of an overall number of trees considered as nature monuments in Poland. Being exposed to a number of agents their health condition often is poor. The wood−decaying fungi are the major age−limiting agents for trees. This paper presents the results of studies on the presence of various fungal species on 160 oak and lime trees. The author makes an attempt to define associations of fungi causing wood decay in ancient oak and lime trees in Poland.

Opis:
Awareness of the importance of the presence of deadwood in forest ecosystems has increased in recent decades. Today, deadwood is not only recognized as a key element in carbon sequestration, nutrient supply and water retention, but is also known to be a reservoir of saproxylic species (species associated with the decay of wood on living and dead trees). The amount of deadwood in clear−cut forest is currently higher than 100 years ago. The issue of how much deadwood and of what quality (including size) there should be in order to promote the conservation of saproxylic biodiversity and sustainable forest management is still vivid. Mycological analyses to determine (i) structure of fungal communities in Scots pine wood debris, (ii) sources and reservoirs of fungi, (iii) nutritional preferences of fungi, and (iv) potential rate and dynamics of wood decomposition were carried out on an ‘old' and ‘fresh' wood (stumps, branches and boughs) from Jedwabno Forest District (north−eastern Poland). Fungi from 62 wood samples were isolated on two artificial media (PDA and SNA) and identified according to their morphology. Eleven species of Zygomycota, 79 of Ascomycota and 15 of Basidiomycota were detected. The majority of species (91%) colonized many samples. Only 9% of species colonized single samples only. The most common species, with high rates of colonization, included Acremonium spp., Alternaria sp., Aspergillus spp., Aureobasidium pullulans, Cladosporium spp., Epicoccum nigrum, Lecythophora spp., Mariannaea elegans, Ophiostoma + Sporothrix spp., Penicillium spp., Phialocephala spp., Phialophora spp., Phlebiopsis gigantea, Phoma spp., Sarocladium strictum, Scytalidium lignicola, Sydowia polyspora, Trichoderma spp. (mainly T. harzianum and T. viride) and Umbelopsis spp. A few species occurred only on stumps or only on branches. More species occurred on 'old' wood than on 'fresh' wood. The average level of sample colonization by a single fungal species was higher (non−significantly) on 'old' than on 'fresh' wood, and on branches than on stumps. The results show that deadwood is a habitat for many fungal species that occur in succession. The presence of deadwood in clear−cut forest and in its neighborhood is necessary for the conservation of saproxylic fungal diversity and ecological sustainability of forests.

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:
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.

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.

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.
