    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:
    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:
    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:
    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:
    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:
    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.

    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.

    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:
    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).
