Opis:
The health status of 6−16−year−old poplars (mostly Populus robusta) in the sanitary protection zones around Legnica and Głogów copper mills (SW Poland) is described. The health of the poplars was assessed as a frequency of trees with symptoms of stem canker and occurrence of virus diseases on leaves. Fungi were isolated from 24 samples of canker wood (20×20×20 cm each) in five afforested complexes and then identified on the basis of colony morphology and sporulation on PDA and SNA after 40 days of incubation. Cankers occurred on <5−95% of poplar trees. Poplar mosaic virus was observed sporadically in collections of P. robusta, P. balsamifera and P. gerlica. The canker wood was colonized by 20 species of facultative pathogens. Acremonium pteridii, Exophiala sp. and Gibberella baccata were the most common and frequent (in 4−5 complexes). Aureobasidium pullulans, Epicoccum nigrum and Fusarium solani occurred in 3−4 complexes. Alternaria alternata, Cadophora fastigiata, Didymella molleriana, Fusicolla aquaeductuum, Gibberella avenacea, Graphium sp., Leptosphaeria maculans, Nectria inventa, Phoma herbarum, P. minutella, Sarocladium strictum, Trichosporon ovoides and Valsa sordida were less frequent and often occurred only locally. The fungi recorded may serve as indicators of the vitality and health status of trees in industrial zones. The best approach to eliminate the risk of colonization by pathogens is to maintain trees in a state of vigorous growth. Management practices that promote good growth include fertiliza− tion, watering during drought, avoidance of unnecessary wounding of trunk and roots, and using correct pruning procedures.

Opis:
The susceptibility of forest trees to Armillaria butt and root rot is described. The paper characterises the most common Armillaria species and presents the mechanical, physiological and chemical mechanisms of plant resistance against Armillaria. The importance of stress as a cause of increased susceptibility of plants to infection is emphasised. Stress in plants may be caused by drought or an excess of water in the soil, inappropriate temperature, unsuitable soil pH, shortage of oxygen in the ground, wrong nutrition, lack of light, pollution of the soil or air, and the presence of damaging macro−, mezo− or microflora and fauna. Stress decreases the production of cambium in the affected area, the production of resins that limit colonisation, the intensity of photosynthesis, respiration and the transport of nutrients. Stress causes the hydrolysis of carbohydrates necessary for production of energy required for resistance responses, increases accumulation of glucose and other substances used by Armillaria, favours the degradation of phenols that limit colonization, increases susceptibility to other stress factors, and decreases regeneration of the trees.

Opis:
The evidence-based hypothesis is presented that the stems and branches of Pinus sylvestris injured by lightning strikes are colonized first by Therrya fuckelii and successively by Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella abietina and Cenangium ferruginosum. The concomitant occurrence of these usually pathogenic fungi on injured Pinus trees in Poland signals a potential for their increased significance in Europe during climatic changes.
Praca stara się udowodnić, że strzały i gałęzie sosny zwyczajnej uszkodzonej uderzeniami pioruna kolonizowane są przez Therrya fuckelii, a następnie przez Diplodia pinea, Nectria fuckeliana, Hyaloscypha leuconica, Gremmeniella abietina i Cenangium ferruginosum. Sukcesja i wspólne występowanie tych, w większości patogenicznych, grzybów na uszkodzonych sosnach sygnalizuje wzrost ich potencjału i znaczenia w Polsce i Europie. Wynikają one z obserwowanych ostatnio zmian klimatycznych i występowania pogody obfitującej w częste burze i wyładowania atmosferyczne.

Opis:
Effects of 62 isolates (of 41 taxa) of fungi on growth of 1-year-old oak (Quercus robur) seedlings were studied in an inoculation experiment. The fungi were isolated from roots of 80–96-year-old Q. robur that had been subjected to periodic flooding and had symptoms of oak decline. The fungal genera included Alternaria, Aspergillus, Calonectria, Chaetomium, Cladosporium, Clonostachys, Corynespora, Cylindrocarpon, Dicyma, Geotrichum, Ilyonectria, Isaria, Metarhizium, Oidiodendron, Ophiostoma, Pezicula, Phialocephala, Phialophora, Pyrenochaeta, Sporendocladia, Sporothrix, Thelonectria, Trichoderma and Trimmatostroma. Mycelial colonies of fungi growing in potato-dextrose broth were used for soil inoculation. Plant growth was assessed 2 years after inoculation, when the plants were 3 years old. Stem lengths, and dry weights of stems, roots and leaves were measured. Stem growth was inhibited by 31 isolates (50%) and root growth by 12 isolates (19%). Stem growth was stimulated by two isolates (3%) and root growth by 17 isolates (27%). The overall ratio of inhibitors to stimulants was 2.1. The proportion of taxa that inhibited stem growth was 16 times greater than that which promoted stem growth. The proportion of taxa that promoted root growth was only 1.5 times greater than that which inhibited root growth. The structure of the fungal communities in periodically flooded oak forests suggests that they are more likely to inhibit than to promote vigour in oaks.

Opis:
The aim of the studies was to check the usefulness of ITS1/2 rDNA and 18S rDNA regions in the molecular investigation of forest soil microbiota structure. Soil studied, originated from a 1−year−old plantation and a 40−year old stand of Scots pine located in Bierzwnik and Międzychów forest districts located 200 km apart. The hypothesis assumed that both approaches lead to the discovery of abundant microbiota communities with different structures and with rare common species. The environmental DNA was extracted with a Power Soil ® DNA Isolation Kit from two soil samples in each site. The ITS1/2 rDNA was amplified with specific primers ITS1 and ewfitsrev 1, and 18S rDNA with universal primers NS1 and NS2. PCR products were cloned into pGEM−T Easy. Inserts were primarily selected in blue/white screening on a X−gal medium. Representative clones were further selected in two separate RFLP analyses with HhaI and BsuRI restriction enzymes. Representative clones purified and sequenced using the Sanger Method in the DNA Research Centre (Poznań). Each sequence was identified to the lowest taxonomic rank. Ninety to 233 clones with DNA of 5−44 taxa including 3−37 taxa of fungi were obtained from 4 samples of soil. After application of ITS1/2 rDNA and 18S rDNA, the fungal DNA was detected respectively in 89,60−100,00% and 11,77−64,8% clones and the number of fungal species detected was respectively 12−37 and 3−19. Fungi were represented by four orders: Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota. Both primers also amplified also DNA of other organisms (mostly from Animalia and Protista Kingdom) represented by 0−9 taxa. If compared, the application of forest soil microbiota structure with ITS1/2 rDNA and 18S rDNA led to detect a lower abundance of fungi and a bigger abundance of other organisms. Considering the higher number of clones and taxa recognized, the region of ITS1/2 rDNA was more effective in the studies of the soil microbiota structure. The region of 18S rDNA was efficient in local detection of Chytridiomycota and Zygomycota and of rare species of fungi from Ascomycota and Basidiomycota. Despite the deficiency of NCBI database the use of the 18S rDNA region in studies on fungal community the region should be included in molecular studies of fungal diversity. It is concluded that studies on the biodiversity of soil microorganisms need the application of a few independent methods of detection and identification.

Opis:
Fungi in soil perform important services related to nutrient cycling, water dynamics and disease suppression. Along with bacteria, they are important as decomposers in the soil food network. Fungi convert hard−to−digest organic material into forms that other organisms can use. They can immobilize or retain nutrients in the soil. Secondary fungal metabolites have the fungistatic properties and are used in biocontrol processes. The hyphae physically binds soil particles together, creating stable aggregates that help increase water infiltration and soil water retention capacity. Fungi help to increase the accumulation of humic−acid rich organic matter that is resistant to degradation and may stay in the soil for hundreds of year.

Opis:
Two different communities of microorganisms were identified in soils by application of the classical method of fungi isolation (soil dilution, culturing on artificial media, morphotyping) and a molecular method (extraction of the environmental DNA, amplification with universal primers NS1 and NS2, cloning and sequencing of representative clones). No organisms were common to both communities. Apart from rare representatives of the Animalia, communities included single fungus−like Eucarya belonging to the Protista, Class Oomycota, and numerous fungi belonging to Chytridiomycota, Zygomycota, Ascomycota and Basidiomycota orders. In total, 88 species were identified in four soil samples. Fungi were mostly Ascomycota. The classical method was particularly effective in detection of fungi important for creation of phytosanitary conditions of soil, i.e. antagonists (Penicillium, Tolypocladium and Trichoderma) and potential stimulants (dark−pigmented Hormiactis candida, Humicola spp. and Phialophora spp.) of phytopathogens (including the common forest genera Armillaria and Heterobasidion). Application of the classical method allowed the detection of mycorrhizal Ascomycota from the genus Oidiodendron. Application of the molecular method allowed the detection of 13 mycorrhizal Basidiomycota. Although primers NS1 and NS2 were designed from a match with DNA of culturable organisms, they also amplified the DNA of non−culturable organisms. This emphasizes their potential usefulness in studies of the biodiversity of microorganisms in environmental samples. The shortage of reference sequences in the database discourages use of the 18S rDNA region in studies on fungal communities. The studies on the biodiversity of microorganisms need the application of a few independent methods of detection and identification.

Opis:
Aspecimen of Goidanichiella sphaerospora was found in Pinus sylvestris forest soil in Międzychód, northwestern Poland (52.601, 15.889883), in October 2009. This is the world’s second record of G. sphaerospora. Bimorphic conidial heads and conidia are reported for the first time. Goidanichiella sphaerospora forms Aspergillus- and Penicillium-like conidial heads. Conidia formed at +24oC are oval to ellipsoidal, often apiculate, smooth, rather thick-walled, hyaline, with one oil drop inside, 3-4 × 2-3 μm. Additional ellipsoidal to cylindrical, thin-walled, 4-6.5 (-8) × 2-3.0 μm conidia are formed only after incubation for at least 7 days at +4oC in darkness.
Goidanichiella sphaerospora znaleziono w glebie leśnej, w młodniku Pinus sylvestris, w Międzychodzie (Polska północna, 52.601, 15.889883), w październiku 2009. Jest to drugie stanowisko tego grzyba na świecie. Poprzednio grzyba stwierdzono w glebie leśnej w Japonii. Grzyb tworzy zarodniki konidialne na bimorficznych konidioforach przypominających konidiofory Aspergillus i Penicillium. Wystepują dwa rodzaje zarodników. W temperaturze 24oC, na PDA i SNA , tworzą się konidia, które są owalne do eliptycznych, ostro zakończone u podstawy, gładkie, grubościenne, hialinowe, z jedną kroplą wewnątrz, 3-4 × 2-3 μm. W temperaturze 4oC, przy braku światła, tworzą się dodatkowe konidia, które są eliptyczne do cylindrycznych, cienkościenne, 4-6,5 (-8) × 2-3,0 μm.

Opis:
Scots pine sawdust, composted bark or coarse, post-harvest woody debris from conifers had been spread over the surface of barren forest soil before planting with Scots pine. The effects of the Scots pine sawdust, composted bark or coarse, post-harvest woody debris from conifers on the abundance and diversity of culturable fungi were investigated. The amendments were aimed at increasing the soil suppressiveness to Armillaria and Heterobasidion. The classical soil-dilution method was chosen for qualitative and quantitative analyses of fungal communities in soils because of its proven reliability and consistency. The soil was inhabited by saprotrophic fungi from Ascomycota and Zygomycota, including species known to be potential antagonists of Armillaria or H. annosum (i.e. Clonostachys + Trichoderma spp., Penicillium commune, P. daleae, P. janczewskii) or stimulants of Armillaria (i.e. Pseudogymnoascus roseus, Trichocladium opacum). Eleven years after treatment, the abundance and diversity of fungi, the abundance of P. commune, and locally the abundance of P. janczewskii increased, while Clonostachys + Trichoderma spp., and locally, P. daleae and T. opacum decreased. Amending the barren soil with organic matter does not guarantee effective, long-term suppressiveness of the sandy loam soil to Armillaria and Heterobasidion. Increased abundance of entomopathogenic and nematophagous species, 11 years after treatment, does suggest the long-term possibility of insect or nematode control in soil.

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:
Phytophthora and Pythium species (Oomycota) are known to be serious pathogens of forest trees. Little is known, however, about their presence in Polish oak forests and their role in the oak decline, especially in the flooded areas. The aim of this study was (1) to detect and compare populations of microorganisms from Oomycota and fungi in roots and soil of healthy and declining pedunculate 30−126 years old oak stands, which had been flooded by the Odra River for three months in 1997 and one month in 2010, (2) to demonstrate the relationship between different chemical factors of soil and the occurrence of microorganisms, and (3) to assess the contribution of Oomycota to oak decline. Study was carried out in Wołów Forest District (south−western Poland). Microorganisms were isolated from fine (1−5 mm in diameter) roots and non−rhizosphere soil collected from 0−50 cm horizon. Isolation procedure from roots included surface sterilization and plating the root segments on the nutrient agar. An oak leaf baiting method was used for isolation of Oomycota from soil. Identification of microorganisms was based on morphology and sequencing of the ITS1/2 rDNA. Oomycota was represented by: Globisporangium, Phytophthora and Pythium and fungi mostly by: Aspergillus, Chaetosphaeria, Cylindrocarpon, Mortierella, Mucor, Penicillium, Trichoderma and Umbelopsis. Globisporangium attrantheridium (syn. Pythium attrantheridium) occurred locally and was found in roots of only one flooded oak. This is the first record of this species on oak and in Poland. G. intermedium, P. gibbosa/P. gregata, P. plurivora and Pythium sp. were found in soil of flooded and non−flooded (control) oak stands. The organisms occurred in podzolized brown soils, brown alluvial soils and gley soils that had most nitrogen (21−60 mg/kg), various amounts of calcium (61.1−347.6 mg/100g) and moderate acidity (pH=3.85−4.2). There was often a significant association between exposure to flood and the health status of oak trees assessed by the scale of defoliation. Oomycota seemed to be only moderately associated with increased tree defoliation as a symptom of oak decline.

Opis:
Two diploid isolates of Armillaria gallica and 143 diploid isolates of A. solidipes were obtained from 145 samples of rhizomorphs, fruit bodies and infected wood of sessile oak and Scots pines from 5–10-year-old Scots pine plantations in three Forest Districts located 100–350 km apart in west-central Poland. Based on pairings among the 145 isolates, 18 somatic compatibility groups (genets) of A. solidipes were distinguished in the three plantations. Sequencing of ITS1/2 rDNA of 18 isolates representing the 18 genets delineated four nuclear haplotypes. This suggests that many of the A. solidipes genets are closely related and were possibly established by sib-related basidiospores. With a few exceptions there was general geographical specialization of genets but not haplotypes. Geographical specialization of genets and the dominance of single haplotypes suggest that the A. solidipes population results from clonal rather than sexual reproduction. Sequencing of the ITS1/2 and IGS-1 rDNA showed small nucleotide diversity in ITS1/2 rDNA and much more diversity in IGS-1 rDNA of the isolates of A. solidipes studied. However, none of these regions has sufficient resolution for the clear differentiation of A. solidipes from A. borealis. The sequences of the EF 1-alpha gene showed high interspecific variability in Armillaria species and very low intraspecific variability in A. solidipes. This gene is the most appropriate for reliable identification of biological species and subgroups of Armillaria. Its application is the most useful in ecological and epidemiological studies of Armillaria.

Opis:
Application of the correct methods of study is essential for a proper description and understanding of natural communities of microorganisms and their relationships. Classical methods used for detection and identification of soil microorganisms resulted in underestimation of the microbiota. It has been claimed that classical methods, based mainly on morphology, led to the identification of only 1% of the soil microbiota, usually species that predominate in culture because of their fast growth and abundant sporulation. Molecular methods allow rapid, accurate, sensitive and cost−effective identification and enumeration of microorganisms. They are designed to replace and/or support classical approaches. This review summarizes some of the current and emerging nucleic acid−based molecular approaches used for detection, discrimination and quantification of microbes in the environment, mostly in soil.

Opis:
Mixture of the Penicillium adametzii metabolites present in the chloroform extract usually did not inhibit the growth of damping−off fungi, including C. destructans, F. oxysporum. F. sambucinum, F. solani and R. solani, in vitro. Extract from the P. adametzii liquid culture: (i) protected the inoculated pine seedlings from the damping−off only temporarily, (ii) decreased the health of the non−inoculated seedlings, (iii) caused the temporary increases of the fungal population in soil, (iv) changed structure of the soil fungi communities, and (v) caused the continuous increase of Trichoderma, mostly T. aureoviride population. The increase of pine seedlings damping−off was connected with the increase of T. aureoviride population in soil. Natural isolates of P. adametzii cannot be considered as the effective biological factor in the biological control of damping−off.

Opis:
The presence of microorganisms in the substrate is detected with increasing frequency using chemical methods. During the first 9 weeks ergosterol concentration in sterile or not sterile soil inoculated with one of the damping−off fungi reached 966 μg/g, while number of colony forming units (cfu) went up to 247×103 cfu/g. Ergosterol concentration was correlated with the size of the soil fungal community estimated in terms of the number of colony forming units in soil. Pearson's correlation coefficient was 0.700−0.946 for sterile and not sterile soil. Higher content of ergosterol was observed for F. sambucinum var. sambucinum, H. haematococca and T. cucumeris while higher average content of cfu was observed for H. haematococca and T. cucumeris.

Opis:
Effects of Scots pine wood amendment on the fungal community in forest soil infested with cockchafers and foraged or non-foraged by wild boars and hares were investigated. We hypothesized that sawdust amendment would increase the abundance of entomopathogenic and insect-associated species effective in cockchafer predation. The soil dilution method and morphotyping were used for fungal isolation and identification in order to quantify and qualify the viable components of the microbiota that are important for evaluating soil functions. There was usually increased abundance and decreased diversity of soil fungi one year after sawdust amendment. Application of pine sawdust more often increased than decreased the abundance of some insect-associated fungi or dermatophytes and keratinophilic species and decreased the number of cockchafer larvae. Abundance of Geomyces pannorum, Mortierella spp. + M. luteus, Pseudogymnoascus roseus, Tolypocladium inflatum and Trichoderma koningii increased, at least locally, whilst Chrysosporium merdarium, Penicillium spp. (including the most common P. citrinum, P. daleae and P. janczewskii), Sporothrix schenckii and Trichoderma spp. decreased. Application of pine sawdust under roots of 1-year-old Scots pine seedlings significantly increased the abundance of Phoma + Pyrenochaeta spp. in neighbouring soil, thus increasing the risk from Phoma blight. Trichoderma strigosum was among the dominants (frequency >5%). Another six and two Trichoderma species were among the subdominants (frequency 1–5%) and subrecedents (frequency <1%), respectively. Dermatophytes, coprophilous and keratinophilic species, e.g. Cephalotrichum, Chrysosporium merdarium or S. schenckii, occurred only or mostly in foraged plots. The altered communities resulting from pine sawdust amendment may contribute to biological control of the cockchafer larvae.

Opis:
The frequency and diversity of fungi in branches, roots and soil was examined in 3–10-years-old diseased Juniperus x media trees growing in the surroundings of the sewage treatment facility in Poznań. Symptoms of branch dieback appeared first on the older parts inside the crown and mostly in the lower part of trees subsequently spreading upwards and outwards. Our analyses included extraction of environmental rDNA from branches, roots and soil, amplification of the rDNA with fungi specific primers and sequencing. Fungal taxa from Ascomycota, Basidiomycota, Chytridiomycota, Glomeromycota and Zygomycota were detected with a total of 695, 135 and 196 taxa in branches, roots and soil, respectively. Fungal communities included plant pathogens, opportunistic pathogens, epiphytes or endophytes, mycorrhizal taxa, saprotrophs common on organic debris and in soil, human and animal pathogens, entomopathogenic taxa, mycoparasites, white and black yeasts, taxa with antagonistic and medicinal properties and lichenized fungi. The frequency of potential plant pathogens was 2.64–33.12% in branches, 0.88% in roots and 1.29–2.93% in soil. The most common pathogens were species from Chalara, Cytospora, Fusarium, Ilyonectria, Mycosphaerella, Setomelanomma (Ascomycota) and Armillaria, Rhizoctonia (Basidiomycota) genera. The less frequent pathogens included species from Leptosphaeria, Lophodermium and Septoria genera. In conclusion, oxygen deficiency and the presence of poisonous gases in the air around the sewage plant is likely to have had damaging effects on plants infected or colonized by opportunistic and facultative parasites.

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:
Occurrence of culturable Fungi and Oomycota in root-soil habitat of potato cv. Owacja in organic and integrated production systems at Osiny (northern Poland) was compared in 2008–2010. The densities of both pathogens were significantly greater in the organic system. The eudominant fungal taxa (with frequency > 10% in at least one habitat) included species of Fusarium + Gibberella + Haematonectria, Penicillium, Phoma and Trichoderma. The dominant taxa (with frequency 5–10%) included species from 13 genera. In the rhizoplane, rhizosphere and non-rhizosphere soil, the total density of potential pathogens was greater in the integrated system, and of potential antagonists in the organic system. Among eudominant and dominant pathogens, Fusarium oxysporum and Gibellulopsis nigrescens occurred at greater density in the integrated system and Haematonectria haematococca and Phoma spp. in the organic system. Among eudominant antagonists, Trichoderma species occurred at greater density in the organic system. The organic system provided more disease suppressive habitat than the integrated system. The occurrence of brown leaf spot and potato blight was however similar in both systems. The mean yield of organic potatoes (24.9 t · ha–1) was higher than the mean organic potato yield in Poland (21.0 t · ha–1) and similar to the mean in other European countries (Germany 25.1 t · ha–1, Great Britain 25.0 t · ha–1). The organic system, based on a 5-year rotation, with narrow-leafed lupin, white mustard and buckwheat as a cover crop, inorganic fertilization based on ground rock phosphate + potassium sulphate, and biological and chemical control of insects and diseases (Bacillus thuringiensis ssp. tenebrionis + copper hydroxide + copper oxychloride), may be recommended for use in central Europe.

Effects of pre−planting soil preparation on the clear−cut on the community structure of soil fungi and bacteria, their possible biological activity towards Armillaria and Heterobasidion, and mortality of Scots pine trees were studied in 40−year−old Scots pine plantation in Międzychód Forest District (W Poland). Pre−planting soil preparation included: (i) deep ploughing, (ii) shallow furrowing, (iii) making holes for planting, and (iv) shallow turning of the topsoil. The soil−dilution method was used for detection of fungi and bacteria in soil. Morphotyping was used for identification of fungi. Phenotypic traits and biochemical properties were used for identification of bacteria. Molecular method, MID−66 or BIOLOG® systems were additionally applied for identification of the most common bacteria. Deep furrowing, making holes for planting or shallow turning of the topsoil before planting increased abundance of fungi and bacteria in soil 40 years after treatment. Increased abundance of fungi and bacteria was associated with increased presence of taxa considered as antagonistic to Armillaria and Heterobasidion. The highest mortality of Scots pines was observed on sites with deep ploughing or shallow furrowing before planting, while the lowest mortality was found on sites with making holes for planting or shallow turning of the topsoil. The majority of dead trees were infected by H. annosum. Moderate intervention into the soil habitat on the clear−cut site before planting of Scots pine seedlings seems to create the habitat beneficial for the future growth of trees.

Opis:
Deadwood is an important functional and structural component of forest ecosystems since it regulates nutrient cycling, serves as a carbon (C) pool, increases the C content in the soil, and is a source of resources, including water, for a wide range of saproxylic and non-saproxylic organisms. The abundance and diversity of wood-inhabiting fungi in six fallen, horizontally lying logs of Quercus petraea, in the 1st, 2nd and 3rd decay classes, in the Drawa National Park in Poland in 2015, were studied using the Illumina se- quencing technique. The total number of OTUs obtained (264 307) included sequences of culturable fungi (242 369 = 91.70%) and non-culturable fungi (7 056 = 2.66%). The dead oak wood was colonized by 277 taxa. Culturable fungi of Zygomycota, Ascomycota and Basidiomycota comprised 75% of taxa detected and were represented by 14, 139 and 53 taxa respectively. Non-culturable organisms were represented by 70 taxa. Fungi were classified into 18 groups: (i) typical soft rot fungi, (ii) phytopathogens potentially hazard- ous to trees, (iii) epiphytes and endophytes or weak, opportunistic pathogens, (iv) ectomycorrhizal species, (v) ericoid mycorrhizal species, (vi) crust fungi, (vii) resupinate basidiomycetes, (viii) saprotrophs and soil fungi, (ix) opportunistic human pathogens causing superficial or systemic mycoses, (x) pathogens of warm- or cold-blooded animals, (xi) ascomycetous yeasts, (xii) basidiomycetous yeasts, (xiii) antagonists of fungi, (xiv) producers of metabolites effective against pathogens, (xv) hyperparasites, (xvi) lichen-form- ing species, (xvii) partners of other fungi, (xviii) species rare or uncommon in nature. It was shown that: (i) coarse, woody debris of oak is host to abundant and diverse mycobiota, (ii) abundance and diversity of fungi increase with the decay continuum, (iii) oak logs can be a habitat of phytopathogens potentially haz- ardous to forest health, (iv) different phytopathogens favour wood in different decay classes, (v) abundance of pathogens decreases, and of ericoid mycorrhizal (or soil) species increases with the decay continuum. Maintaining different types of deadwood increases fungal diversity, but also the risk of diseases.

Opis:
Incidence of Armillaria root disease and the population structure of associated Armillaria spp. were studied in 5-17-year-old Scots pine plantations in west-central Poland. Two infection centres (1.14– 9.30 ha) in each of three forest districts (Siemianice, Zielonka and Złotów) were intensively sampled. Root collars were examined for mycelial fans, decayed wood, and rhizomorphs. Twenty two isolates of Armillaria ostoyae collected from epiphytic rhizomorphs from 20 living and two dead trees in the six infection centres were identified with somatic incompatibility group. Only one somatic incompatibility group for A. ostoyae was found. Twenty one isolates produced rhizomorphs on oak-wood discs submerged in a sand-forest soil substrate. Isolates from Siemianice formed the smallest rhizomorph networks and those from Złotów the most abundant. There were 16 different genets among 22 isolates of A. ostoyae distinguished by RAPD analysis. Genetic similarity among genets was 25.6–97.5%. The large diversity in A. ostoyae suggests that sexual reproduction may occur in nature more often than expected.

Opis:
Effects of post−harvest wood−debris utilization and pre−planting soil preparation in clear−cut forest on the community structure of soil fungi and bacteria and their possible biological activity towards Armillaria and Heterobasidion were studied in 1− and 10−year−old Scots pine plantations in Bierzwnik and Międzychód Forest Districts (W Poland). Post−harvest wood−debris utilization included: (i) removal from the surface, (ii) spread of the coarse or chipped wood−debris on the surface and (iii) mixing of the chipped wood debris with the soil. Pre−planting soil preparation included: (i) deep furrowing, (ii) shallow turning of the topsoil, (iii) ridging and (iv) no ground preparation. The soil−dilution method was used for detection of fungi and bacteria in soil. Morphotyping was used for identification of fungi. Phenotypic traits and biochemical properties were used for identification of bacteria. Molecular method, MID−66 or BIOLOG® systems were additionally applied for identification of the most common bacteria. Removal of post−harvest wood−debris from the surface of the clear−cut land and shallow turning of the topsoil or ridging before planting increased abundance of fungi in soil of 1−year−old Scots pine plantation. Deep furrowing resulted in increased abundance of fungi and no ground preparation in increased abundance of bacteria in soil of 10−year−old Scots pine plantation. Increased abundance of fungi and bacteria was associated with increased abundance of taxa considered as antagonistic to Armillaria and Heterobasidion. Removal of the post−harvest wood debris and moderate or no mechanical intervention into the soil habitat on the clear−cut site before planting of Scots pine seedlings seems to create the habitat, which may be beneficial for the growth of young trees.

Opis:
Dutch elm disease (DED) still occurs in Poland. Previous studies confirmed occurring O. ulmi and two subspecies of O. novo-ulmi: subsp. novo-ulmi and subsp. amerciana. In this study the population of Ophiostoma occurred in Poland was investigated. The disease incidence was investigated on elms growing in 39 locations. The pathogen’s mycelium was isolated from elm branches and twigs collected from 22 plots. The disease symptoms were noted in 5% to 35% trees. Fungi were identified based on the PCR amplification of the ITS 1/2 rDNA together with phylogenetic analysis of this region. Ophiostoma novo-ulmi was the only agent caused DED on Ulmus glabra, U. minor and U. laevis. There were no genetic diversity of O. novo-ulmi Polish population in analyzed ITS region. All kind of specific symptoms and disease intensity occurred independently on elm species and host age. Ulmus minor was infested most sever among the three elms species.

Opis:
Pedunculate oak (Quercus robur L.) is the most valuable deciduous tree species in Poland. For almost 30 years, an oak decline resulting from stress factors leading to a decrease of tree vitality in the long-term has been observed. The aim of the present study was to determine the proportion of leaves infected by the fungus Erysiphe alphitoides, the cause of powdery mildew, in post-flood oak stands situated in the Forest District Wołów (51°32’N, 16°62’E) as well as to evaluate effects of powdery mildew with respect to the oak decline. In order to record the powdery mildew incidence, we selected three trees in each of the ten investigated oak stands, and 200 leaves were collected from the upper part of the crowns. The percentage of infected leaves as well as the reduction of carbon assimilation capacity was assessed. Furthermore, we evaluated the average reduction of carbon assimilation capacity and the percentage of withering branch tips in 25 adjacent trees. Incidences of powdery mildew were observed in seven out of the ten stands. The maximum tree damage did not exceed 22% leaf infection and mean defoliation within the study areas ranged from 18% to 61.4%. Non-withering branch tips were observed in one post-flood area as well as in one area situated outside the flooded region. Within the remaining areas studied, the average proportion of withering branch tips ranged from 0.4% to 13.8%. Statistical analyses showed that differences between the investigated stands with regard to the rate of powdery mildew occurrence were not significant. Correlating the means, however, revealed a relationship between powdery mildew incidence and branch tip withering. This relationship is a possible indication of the ongoing oak dieback. No statistically significant relationship between tree defoliation and powdery mildew incidence was found. The lack of statistical significance, as observed here, implies that water stagnation within the investigated stands had no effect on Erysiphe alphitoides infection.

Opis:
Effects of different pre-planting soil preparations and post-harvest wood debris applications in a clear-cut Scots pine plantation, on the abundance, diversity, and activity of culturable microorganisms were investigated. The investigation was done 9 years after the re-plantings had been done. This formed part of an investigation of silvicultural practices for conservation and the biological control of Armillaria and Heterobasidion in northern temperate forests (Poland). The treatments being compared, were expected to have altered the soil’s physical and chemical properties, and consequently, its biological properties. Only soft-rot microfungi from the Ascomycota and Zygomycota were detected in the soil. Fungi, including those antagonistic to Armillaria and Heterobasidion, were more abundant after shallow ploughing than after deep ploughing or ridging, and where chipped rather than coarse wood debris was left on the soil surface or incorporated. Scots pine trees had the most biomass and the least mortality after ridging and leaving coarse wood debris on the surface (associated with only a relatively moderate abundance of fungi).
