Opis:
The important role of mycorrhizae for plants, particularly those introduced to hardly−regenerating post−agricultural areas, post−industrial areas or degraded soils, promotes use of artificial mycorrhizal inocula. Their effectiveness depends, to a large extent, on the species or rather strain of a fungus. Analysing the resistance of strains isolated from contaminated and uncontaminated areas attempts were made in the paper towards solving the question about the role of the origin of mycorrhizal fungi used for mycorrhization. Also attempts were made to verify the hypothesis that symbiotic fungi growing in degraded areas are selected and adapted to unfavourable environmental conditions. It was shown that the resistance of fungi, even of the same species, to high concentrations of heavy metals, differ depending on the symbiont's origin. Fungi isolated from contaminated areas are better adapted to high concentrations of xenobiotics.

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:
The effect of two fungicides Falcon 460 EC and Gwarant 500 SC on the state of mycorrhizae and growth of 2−year−old pine seedlings in natural regenerations was investigated. Any of the tested fungicides did not cause changes in the level of mycorrhizal colonisation and seedling growth. Both fungicides had a limiting effect on the formation of one of mycorrhizal morphotypes and development of complex forms produced by this morphotype.

Opis:
The effect of two fungicides Falcon 460 EC and Gwarant 500 SC used at recommended rates and concentrations to protect seedlings in the natural regeneration of Scots pine against Lophodermium needle cast was investigated. Also, the effect of the fungicides on the status of mycorrhizae and growth of seedlings was assessed. Single or twofold application of Falcon or Gwarant to pine seedlings during the growing season may appear insufficient to provide complete protection against Lophodermium needle cast, especially when the threat of infection is higher. Falcon was found to be more effective in protecting pine seedlings against Lophodermium needle cast in comparison with Gwarant. None of the tested fungicides had a limiting effect on the formation of mycorrhizae and growth of seedlings. Both fungicides had a slight limiting effect on the formation of complex dichotomous and coralloid structures only in one−year−old pines.
