Opis:
Heterobasidion annosum (Fr.) Bref. is a fungal pathogen causing root rot – one of the most economically important diseases in coniferous stands in Europe, Asia and North America. A major objective of this study was to determine if the offspring of self-sown trees from natural regeneration in old foci of root rot is more resistant to infection by this pathogen than the offspring of plus trees. In experiments conducted in the greenhouse above 700 seedlings grown from seeds collected from 60 trees in 6 old foci of the disease (research plots) and 480 seedlings grown from seeds collected in 4 seed orchards were used. The pathogen was represented by 7 different fungal strains. Plus trees, whose grafts are used to establish seed orchards, were the selected elite of forest trees, but their offspring after inoculation with H. annosum had significantly worse results than the seedlings developed from the seeds collected in old foci of the disease (research plots). The greatest differences were observed in seedling dry weight. In inoculated seedlings from seed orchards it was 14% lower than in the control, while the dry weight of inoculated seedlings from research plots did not differ significantly from that of non-inoculated seedlings.

Opis:
Until recently, the level of industrial air pollution in the Sudetes (a mountain range extending on the Czech Republic and Poland border) was very high.This caused a large-scale forest decline, especially in the western part of the Polish Sudetes: in the Izerskie and Karkonosze Mts. An analysis of data on fir defoliation in that area, collected directly after the period of heavy industrial pollution, showed a clear dependence of the degree of defoliation of the primary crown on canopy density: the lower the density, the higher the degree of defoliation.

Opis:
Japanese larch (Larix kaempferi Sarg.) is one of the most frequent exotic species in Polish woodlands. The basic object of research comprised 60 stands of the studied species, located mainly in the northern and western parts of Poland. The growth results for the studied species, evaluated on the basis of the average height (hg55), were compared with data describing the local climate and the stand location within the botanical and climatic zoning. The results confirm the opinion that the Japanese larch prefers a climate of maritime character and generally shows high degree of flexibility regarding its climatic requirements (very large differences between the growth conditions in the studied area and the country of origin). The dependence between the growth results and precipitation is however lower than expected. The most interesting results include the relatively clear connection between the height of the larch stands and the Degórski’s (1984) ‘floristic’ ‘K’ (continentality) index.

Opis:
Three elm species are native to Poland: wych elm (Scots elm) (Ulmus glabra Huds.), field elm (U. minor Mill.), and European white elm (fluttering elm) (U. laevis Pall.). The epidemic of Dutch elm disease (DED) has led to a decrease in the popularity of elm cultivation. An analysis of forestry data was the first step in the assessment of elm resources. The area of forest stands where elms are dominant has more than doubled since 1978. Lowland alluvial forests rank first in regards to the number of elm localities per unit area of a given forest site type. While this site type is clearly preferred by elms, the majority of elm trees are actually scattered among sites of oak-hornbeam or closely related forests (of the alliance Carpinion betuli). Field research revealed a clear dominance of U. laevis, a species which in the past was predominantly located out of woodland and rarely cultivated. Data analysis indicated that all trees greater than 70 cm in diameter belonged to this species. Data from plots surveyed directly also suggest that the three elm species have slightly different habitat preferences. U. laevis prefers riparian habitats, although the major part of its resources is now on potential sites of oak-hornbeam or closely related forests. U. minor even more often than U. laevis occurs at less humid sites (mostly potential sites of oak-hornbeam or closely related forests), while U. glabra prefers moist slopes. In general, it appears that the impact of DED in the last 20–30 years has been smaller than in the preceding period, however, the disappearance of the disease has not been established. Undoubtedly, U. laevis is the elm species that is least impacted by DED

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.
