    Opis:
    This review is based on our observations and detailed studies conducted in more than 100 bare−root forest nurseries in Poland. We concentrated on recent work on ectomycorrhizal community structure of most common forest trees (pine, spruce, larch, oaks, beech and birch). The following issues are addressed: fungal diversity, host specificity and age, ascomycetes or basidiomycetes predominance, and exploration types of mycorrhizae as well as edaphic factors.

    Opis:
    Pedunculate oak (Quercus robur L.) is among the major managed tree species in Europe. In Poland, oak woodlands cover 6.9% of forest area. Furthermore, the significance of native oaks for Polish forestry is rising because the Polish National Forest Strategy predicts a growth of forest cover from 28.5% to 33% by year 2050 with the primary focus on the increase in contribution of deciduous tree species (from 22% to 33%). Therefore, for establishment of new stands, oak seedlings are grown for 2−3 years in forest nurseries. For optimal growth and development all European oak species are critically dependent on ectomycorrhizal fungi. The objective of this study was to describe the temporal dynamics of ectomycorrhizal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery. Experiment was conducted in forest nursery Miranowo (western Poland). The species structure of an ectomycorrhizal community was assessed every 10 or 15 days from May till October. Mycorrhizal colonization of tested seedlings changed from 0 to 85% depending of the time of sampling. Based on combination of morphological and molecular techniques, nine ectomycorrhizal fungal taxa were distinguished. The first ectomycorrhizas formed by Scleroderma verrucosum were detected 50 days after acorns sowing. In the next sampling days ectomycorrhizal community was dominated consecutively by Inocybe curvipes and Hebeloma sacchariolens (with maximum of abundance 60.98 and 75.55%, respectively). The obtained results were strongly influenced by the infection with the fungal biotroph Erysiphe alphitoides and resulted in a dramatic reduction in the abundance of living ectomycorrhizas down to 7.5%. Our investigation revealed that ectomycorrhizal fungal community of pedunculate oak seedlings during the first year of growth in bare−root forest nursery is rich in terms of number of species and a temporal changes are very dynamic. Thus we suggest, that in case of pedunculate oak artificial inoculation in general is not necessary for oaks seedlings in nursery practice.

    Opis:
    Ectomycorrhizal communities associated with Pinus sylvestris growing on dry coniferous forest habitat after the fire were studied. In order to investigate the fire effect on ectomycorrhizal fungi and changes of soil parameters in the upper (0−15 cm) soil layer three study plots were established: 1 – the control, 2 – fire zone left for artificial renewal (with the economic method of renewal) and 3 – fire zone left for natural renewal. The analysis of mycorrhizae revealed presence of eight mycorrhizal fungi on Scots pine roots and the value of Shannon−Wiener species diversity index H’ equaled to 1.76. The most abundant were mycorrhizae formed by Tomentella feruginea (31.7%) and Hebeloma crustuliniforme (23.3%). The fraction of Paxillus involutus and Rhizopogon sp. mycorrhizae was 16.7% and 13.0%, respectively. The lowest was the number of Thelephora terrestris mycorrhizae (only 1.7%). At the site 2, number of mycorrhizal fungi diminished to five and Shannon−Wiener species diversity index was also lower (1.37). The predominant were mycorrhizae of Cenococcum geophilum (26.7%) and P. involutus (21.7%), whilst the lowest were mycorrhizae of Suillus luteus (1.7%). Although at the third site the number of ectomycorrhizal fungi was the same as on the site 2, the dominance of Thelephora terrestris (66.7%) caused that Shannon−Wiener’s species diversity index was the lowest (1.05). Mycorrhizae of Paxillus involutus and Wilcoxina mikolae were characterised by similar abundance (13.3% and 11.7%, respectively). The lowest number of mycorrhizae was observed for Tomentella sp. (3.3%). Analysis of soil parameters showed an increase of pH on burnt sites in comparison to the control. The soil of burnt sites were also characterised by lower value of C and C/N ratio than the soil on the control treatment. The result showed that ubiquitous mycorrhizal fungi, such as T. terrestis, are able to persist on roots in changed soil environment with low content of nutritions.
