Opis:
Two field inoculation experiments were conducted to study intraspecific variation in vertical spread of the P-, S- andF-IS-group isolates of Heterobasidion annosum in stems of Pinus sylvestris, Picea abies and Abies alba. Host-plants were inoculated with four isolates of each IS group after 10 mm long wounds made with a sterile knife (experiment 1) or 3 mm diameter radial holes made with a drill (experiment 2). On pine, the P-group isolates were more virulent than S andF isolates in terms of infection frequency, mortality rate andvertical spread in sapwood. The S isolates had higher incidence of infection and extensive growth on spruce than on pine. The F isolates were significantly less virulent on pine andspruce than on fir. Vertical spreadof all IS groups on fir was similar. In spite of between-strain-within-IS group variation in vertical spreadon each host, the study provided strong evidence for the occurrence of intraspecific differences in the host preference. In the interspecific analysis with three hosts, the isolates, IS groups andhost × strain andhost × IS group interactions accountedfor most of the explainedvariation, while host-plants accountedfor the smallest portion of the variance.

Background. Although the parasitofauna of wild carnivorous mammals in Poland is quite well recognized, there has been only one research carried on this issue so far in Białowieża Forest - the last lowland primeval forest of temperate zone in Europe. Material and methods. Twelve wild and two domestic species of carnivorous mammals are living in Białowieża Forest. In our work faeces or intestines of all of them except ermine (Mustela erminea) have been examined and parasites or their eggs (or oocysts) recorded. In total 222 faecal probes from 13 species and 11 intestines of weasels have been investigated. Results. All species of examined carnivorous mammals were infected with parasites. The most infected species has occurred red fox Vulpes vulpes (over 70% infected with parasites) meanwhile only about 30% of otters Lutra lutra were infected. We found at least three protozoan species, one trematode, one tapeworm and nine species of nematodes. Except trematode Alaria alata, all of them are reported for the first time from Białowieża Primeval Forest. Oocysts of coccidia have been found in faeces of nine host species, with the highest prevalence (29.4%) in badger. Six species of carnivorous mammals have been occurred infected with trematodes (highest prevalence 42.1% in wolves) and two with tapeworms (Diphyllobothrium latum with the prevalence 2.6% in otter and 31.6% in wolves). All examined host species were infected with nematodes (with prevalence from 14.7% in lynx to 72.7% in red fox). Results of our work should be treated as preliminary researches on the species composition of parasitic fauna invading carnivorous mammals in Białowieża Primeval Forest.

Tolerance of several strains of the P-, S-, and F- intersterility groups of Heterobasidion annosum to low pH and high concentration of aluminium ions was studied on malt extract agar. There were marked intraspecific, but not intergroup, variations in tolerance to both factors. Some strains were relatively tolerant or sensitive to low pH and aluminium, while the others were tolerant to low pH but sensitive to Al. There was no relationship between tolerance of the strains to low pH and their tolerance to aluminium stress.

Opis:
Investigations of genetic diversity of Heterobasidion spp. in Scots pine, norway spruce and european silver fir stands indicated that almost all of identified genets occurred in those stands were small occupied only a single stump. in some cases two, three or even four genets could effectively exist in an individual stump. genetic similarity of H. annosum s.s. genets varied from 0% to 62%, H. parviporum from 0% to 38% and H. abietinum from 0% to 55%. the oldest and biggest genet was found in laying fir log and overgrew the wood for at least 14 years. this genet belonged to H. abietinum. the size of genets was related to thinning operation, spore dispersal, age of stand or competition in wood colonization.
Badania nad zróżnicowaniem genetycznym gatunków rodzaju Heterobasidion w drzewostanach sosnowym, świerkowym i jodłowym wskazały, że niemalże wszystkie genotypy wystę-pujące w badanych drzewostanach były małe i zasiedlały co najwyżej jeden pniak. wkilku przypadkach stwierdzono występowanie dwóch, trzech, a nawet czterech genotypów w jednym pniaku. Podobieństwo genetyczne genotypów H. annosum s. s. wynosiło od 0% do 62%, H. parviporum od 0% do 38%, a H. abietinum od 0% do 55%. najstarszy i największy genotyp stwierdzono w leżącej kłodzie jodłowej, której drewno przerastał, przez co najmniej 14 lat. ten genotyp należał do H. abietinum. rozmiar genotypów był związany z intensywnością cięć pielęgnacyjnych w drzewostanach, rozprzestrzenianiem zarodników, wiekiem drzewostanów oraz konkurencją w zasiedlaniu drewna pomiędzy genotypami.

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:
Prepenetration and penetration phenomena after inoculation of roots of Pinus sylvestris seedlings grown in vitro with the P-, S- and F-group isolates of Heterobasidion annosum were observed using scanning electron microscop. There were no differences in the behaviour of hyphae and in the appearence of mycelia formed by the three IS-group isolates. Four types of the root penetration by hyphae were observed. In the first, the entrace of hypha into root was achieved throught tiny pore formed in walls of the cortical cells. In the second, swellings resembling appressoria were formed by the hyphal tips at the points of contact with the root surface. In the third, the hyphae penetrated cells through holes in eroded areas of roots, and in the fourth by the natural crevices at points of the cortical cell junctions. It is concluded that the different frequencies of the four types of penetration observed after inoculation with isolates of the three IS group should be carefully explained in term of their different pathogenic and saprobic capabilities on pine.

Opis:
The growth of hyphae and prepenetration phenomena on Abies alba roots after inoculation with the P-, S- and F-group isolates of Heterobasidion annosum were observed using scanning electron microscope. Elongated hyphae emanating from the inocula grew indiscriminately across and along root tips and entered the cortical cells randomly, while in subapical root areas they quite often grew along grooves at points of cell junctions. The ridges, folds and depressions seen on the root surface obviously directed the hyphal growth and their further entrance into roots through natural crevices or cracks. Although hyphae of all the isolates could penetrate the roots directly through small openings, the hyphae of the F isolate penetrated preferably more eroded and older parts of roots. A peculiar habit of the direct penetration, characterized by formation a structure resembling infection peg, was observed only after inoculation with the P and S isolates. It is suggested that specifically frequent penetration the roots in eroded areas by the hyphae of the F isolate may be one of the factors connecting with its lower pathogenic capabilities.
