    Opis:
    One−year−old pine seedlings were raised in the open−terrain nurseries in Biłgoraj and Spała. Part of the seedlings were treated with fungicides, the untreated seedlings were used as a control. The level of myc−orrhization was determined on the basis of the number of autotrophic and mycorrhizal apices along the root system. Differences in the results were defined on the basis of the samples 0.1, 0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.8 and 0.9 of the root length. The greatest difference ±18.2% was found for one of the variants sprayed with fungicides in the nursery in Spała for the sample 0.1, and the smallest –0.1% – for the vari−ant with Gwarant and the sample 0.9 and +0.1% for the variant with Sadoplon and the sample 0.4 in the nursery in Biłgoraj.

    Opis:
    Basing on recent findings and experiments of the State Forests National Forest Holding with controlled seedling mycorrhization, the new research and practical needs have been presented. They should serve the broadening of the spectrum of fungal species to be applied in controlled mycorrhization of trees and embracing a broader species and age range of trees and shrubs subject to mycorrhization treatments in the future.

    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:
    Scots pine (Pinus sylvestris L.) seedlings which were inoculated with ectomycorrhizal fungus – Thelephora terrestris and grown in different regimes of N fertilization [Hilszczanska, Sierota 2006], next year were planted out on post−agricultural land. The development of fine roots after 6 months of vegetation, number of mycorrhizas, identity of some mycorrhizas and growth parameters of Scots pine seedlings were studied. Mycorrhizal abundance was higher in the inoculated previously variants than in non−inoculated ones. PCR RFLP analysis confirmed share of two different isolates of Thelephora engaged in mycorrhizal symbiosis. Growth parameters was higher in non−inoculated seedlings. Vitality of seedlings was lower at lower level of N fertilization in non−inoculated treatment.

    Opis:
    The effects of tree genotype on below−ground ectomycorrhizal fungal communities of 40 years old European larch from Kowary, Bliżyn, Świętokrzyski National Park and Szczytna Śląska origins was investigated. The research was carried out in the provenance trial in the Experimental Forestry Unit in Krynica Zdrój (Beskid Sądecki Mountains, S Poland). Ectomycorrhizal fungal communities were assessed by a combination of morphological and molecular techniques. In total 22 fungal taxa has been distinguished (from 17 to 20, depending on larch provenance). Thirteen ectomycorrhizal fungal taxa were common to all analysed origins. The mean taxa richness, Shannon diversity and Simpson dominance coefficient did not differ significantly between provenances. Based on fungal taxa composition (Jaccard coefficient) tested larch origins were characterized by a high level of similarity of ectomycorrhizal fungal communities. Six detected fungal taxa have not been previously reported as symbiotic partners of European larch.

    Opis:
    The effects of pine and oak forest litter on mycorrhizal status of 2−year−old Pinus sylvestris L. seedlings grown in a bare−root nursery was investigated. The research was carried out in the nursery of Vilnius University Botanical Garden in Lithuania. Ectomycorrhizal communities were assessed by a combination of morphological and molecular techniques. Statistical analysis revealed significant effect of litter treatment on some growth parameters of seedlings: seedling height, needle dry weight and total seedling weight. The survival rate of seedlings was significantly highest for oak litter, intermediate for pine litter, and lowest for control soil. Pine seedlings were colonized by indigenous ecto− and ectendomycorrhizal symbionts. Seven mycorrhizal species (Suillus luteus, S. variegatus, Wilcoxina mikolae, Tuber sp., Tomentella sp., Cenococcum geophilum, Amphinema byssoides) were distinguished on the roots of pine seedlings as well as one ectomycorrhizal symbiont not identified to species level. In total, 6 mycorrhizal types were found in control soil, 5 in pine litter, and 8 in oak litter. Suilloid (S. luteus and S. variegatus) and Wilcoxina mycorrhizae were dominant on tested seedlings, irrespective of litter addition. Seedlings grown in untreated nursery soil were 34% colonized by W. mikolae, while suilloid mycorrhizae were dominant after litter treatment (81% in pine litter and 63% in oak litter). We may conclude that suilloid mycorrhizae are better adapted to the conditions related to litter addition than W. mikolae.
