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:
The objective of the research was to study the Armillaria root rot dynamics in the experimental plantation with Scots pine (Pinus sylvestris L.) seedlings non−mycorrhized and mycorrhized with the fungi Hebeloma crustuliniforme and Laccaria bicolor. It was demonstrated that eight years after planting, the container−grown pine seedlings mycorrhized with the fungi H. crustuliniforme were affected by the Armillaria root rot disease in relatively lesser degree in comparison with the seedlings subjected to such treatment.

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).

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:
The economic significance of aspen Populus tremula L. is only marginal, which is the main reason for its low share in the structure of stands. However, aspen can play a decisive ecological role as a pioneer tree in the succession of forest communities and may decrease the occurrence of pathogenic fungi. Aspen is also dying out and in order to determine possible biotic causes, we examined taxa of fungi using classical and mo- lecular methods in the area of the Czerwony Dwór Forest District, Subdistrict Rogale, compartments 74b and 75j. The health of aspen trees and the quantitative and qualitative structure of microorganisms associated with Armillaria spp. was evaluated. Based on our health assessment of the aspen, we conclude that the main reason for its dying out is the intensification of root rot, which is a result of Armillaria spp weakening the trees. In the general pool of Armillaria-associated microorganisms, sapro- trophs were dominating, and the fungus Fomitopsis pinicola commonly inhabited the poplar stems, whereas pathogen antagonists comprised the lowest proportion. In the quantitative and qualitative structure of fungi found in rhizomorphs, the composition of ecological groups inhabiting stumps was found to be favourable nevertheless. The increasing frequency of pathogens on the logs is a major premise for removing trees affected by Armillaria, because aspen stumps are a good food base for A. cepistipes and A. ostoyae which ultimately spread within the stand. Treatment of stumps with preparations stimulating the decomposition of wood is not recommended for logs that form the food base for pathogenic fungi.

Opis:
Black alder Alnus glutinosa (L.) Gaertn. is an important forest−forming species in Poland, with more than 5% participation in the species structure. It is a typical lowland species, especially in the river valleys, on the banks of the lakes and in the land depressions. It is one of the main species in the following habitats: boggy mixed broadleaved forest, alder and alder−ash forest, riparian forest and moist broadleaved forest. As a valuable admixture alder is introduced in the habitat of boggy coniferous forest and boggy broadleaved forest. Until recently black alder was considered in Poland as a species with a very low level of danger from the pests and diseases. The situation changed at the turn of the centuries, when the deterioration of the health status of the alder stands began, which led locally to the mass dieback of the trees, mainly in the stands which are over 20 years old. In the following years, the phenomenon was intensified. The largest number of such stands was recorded in 2006. The strongest deterioration of health condition of the trees was observed in five regional directorates of the State Forests: Białystok, Lublin, Torun, Wrocław and Olsztyn. The study gives information on lignicolous fungi found on black alder in 62 alder stands, which exhibited the most severe signs of the dieback. The research was conducted in 14 forest districts and in Poleski National Park (fig.). The surveys revealed the presence of 49 taxa of the lignicolous fungi (44 Basidiomycota and 5 Ascomycota). The most common species were Xanthoporia radiata, Stereum hirsutum, Daedaleopsis confragosa, Armillaria spp. as well as S. subtomentosum (tab. 2). The disease contributing to the local dieback of black alder in the stands (mainly in the Lublin Regional Directorate of the State Forests) is the root rot caused by Armillaria species. Many species of lignicolous fungi (e.g. Fomes fomentarius, Fomitopsis pinicola, Ganoderma applanatum) penetrate into previously weakened trees, causing decay of wood, which can accelerate the dying of single trees.

In pure medium, T. harzianum exhibited stimulating effect on rhizomorphs of A. borealis (both number and length) and A. ostoyae (only initiation). Cu++ salt totaly inhibited the initiation of rhizomorphs of Armillaria borealis, A. gallica and A. ostoyae. Effect of other compounds on the activity of T. harzianum depended on Armillaria species. The majority of chemical compounds tested supressed the activity of non-volatile metabolites of T. harzianum. Evident stimulating effect was observed under influence of sulphate salts consisting Al++ and Fe+++ on the rhizomorph number of A. borealis and A. gallica, respectively.

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:
Armillaria root disease is one of the most important diseases causing losses in forestry, horticulture, pomiculture and agriculture. Fungi from Armillaria spp. infest roots and stem base in trees and shrubs, causing white wood rot. In Poland the most common species include Armillaria ostoyae (Romagn.) Herink, found both in coniferous and deciduous stands, and A. gallica Marxm. et Romagn. found in deciduous stands. Identification of antagonistic interactions between microorganisms in the soil medium enables to use their activity to protect plants against pathogens. Analyses were conducted on two Trametes versicolor isolates TR31 and TR55, collected from oak stumps, and 5 fungal species from the genus Armillaria: A. borealis Marxm. et Korhonen, A. cepistipes Velen., A. gallica, A. mellea (Vahl) P. Kumm. and A. ostoyae. Profiles of volatile compounds produced by T. versicolor isolates TR31 and TR55 determined in this study varied in their effect on growth of pathogens Armillaria borealis, A. cepistipes, A. gallica, A. mellea and A. ostoyae. TR31 more effectively than isolate TR55 inhibited growth of fungi from the genus Armillaria. Profiles of volatile compounds biosynthesised in the examined fungal cultures were assessed by headspace microextraction in a gas chromatograph coupled with a mass spectrometer. We detected 179 compounds in the analysed fungal cultures. They belonged to the following groups of chemical compounds: amines, alcohols, terpenes, aldehydes, ketones, hydrocarbons, heterocyclic compounds, esters and aromatic compounds (tab. 2). The most numerous group among the isolated volatile compounds comprised hydrocarbons, alcohols and esters at 32.4%, 16.2% and 14.5%, respectively. The highest concentrations reported in RU (i.e. the peak area of a given substances in relation to the peak area of the internal standard, i.e. tridecane) were recorded for aldehydes, alcohols and hydrocarbons. Among all the identified volatile compounds the highest concentration was observed for 2−methylbutanal. However, it was characteristic only of isolate TR31, which exhibited a greater capacity to inhibit growth of Armillaria spp. in comparison to isolate TR55 (fig.).

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:
Comparative cultivation experiment was carried out in the greenhouse to verify the assumption that increased air CO2 concentration (up to 1000 ppm) stimulates the infection intensity and mortality rate of Scots pine and Norway spruce seedlings subjected to the artificial inoculation with Armillaria ostoyae (Romagn.) Herink. It was found that increased air CO2 concentration reduces the intensity of pine and spruce seedlings infection by A. ostoyae, what was expressed both by the greater number of healthy and lower number of died seedlings at the end of 16−months−long experiment. However, the statistical significance of the observed differences was confirmed in case of only one out of three A. ostoyae isolates used in the experiment. It was also found that during the first 12 months of the experiment growth of pine and spruce seedlings was significantly stimulated by 1000 ppm air CO2 concentration compared to the ambient air conditions (approximately 380 ppm CO2) with not statistically significant effect of A. ostoyae presence. It was manifested for both tree species with significantly higher values of diameter at the stem base in all variants subjected to increased air CO2 concentration. No such difference was observed for the height of seedlings. All the findings suggest that elevated air CO2 concentration may compensate negative impact of disease on growth at the early stages of pathogen attack.
