Opis:
Soil salinity is an important abiotic stress factor that reduces both plant growth and development and decreases diversity and metabolic potential of microorganisms, particularly fungi. However, some fun- gal isolates, including mycorrhizal fungi, can increase tolerance of plants to salinity, e.g. by activation of de- fense mechanisms. Main aim of our study was: (i) to identify and characterize fungal strains isolated from fruitbodies growing at saline test sites and (ii) to determine the effect of fungal inoculation on the growth and salinity tolerance of Alnus glutinosa Gaertn. seedlings. Two ectomycorrhizal strains (Amanita muscaria OW-10 and Paxillus involutus OW-5) and a saprotrophic one (Gymnopus sp. OW-6) were isolated from fruit- bodies collected at naturally saline test sites. The plant growth promotion was observed after inoculation of plants with the ectomycorrhizal fungus – P. involutus OW-5, while the use of Gymnopus sp. OW-6, displaying the highest hydrolytic activity, decreased seedling growth parameters. Moreover, P. involutus OW-5 (char- acterized by characterized by medium salt tolerance salt tolerance) promoted growth of black alder in the presence of salt, while A. muscaria OW-10 (with the highest salt tolerance) increased fresh and dry mass of seedlings only in the absence of salt. Black alder seedlings inoculated with P. involutus OW-5 revealed higher synthesis of proline in aboveground organs compared to the control plants which suggested that accumulation of this compound can be a mechanism protecting black alder seedlings against salt stress. In conclusion, we recommend the use of P. involutus OW-5, which displayed the best plant growth promoting ability and salt tolerance, for inoculation of black alder trees used in reclamation of saline habitats

Opis:
In this study, we examined the effect of the presence of mycorrhiza and ascomata of summer truffle (Tuber aestivum) on the bacterial composition of roots from small trees growing in selected sites of the Nida Basin. Qualitative DNA sequencing methods such as Sanger and next-generation sequencing (NGS) were used. The Sanger method revealed different bacterial species compositions between the samples where summer truffle ascomata was recorded and control samples. Five genera of bacteria could be distinguished: Bacillus, Erwinia, Pseudomonas, Rahnella and Serratia, among which the most numerous were Pseudomonas (Gammmaproteobacteria class) at 32.9%. The results obtained by the NGS method also showed differences in species composition of the bacteria depending on the study sample. Seven genera of bacteria were distinguished: Rhizorhabdus, Methylotenera, Sphingomonas, Nitrosospira, Streptomyces, Methyloceanibacter and Niastella, which dominated in roots from the truffle sites. Telmatobacter, Roseiarcus, Granulicella, Paludibaculum, Acidipila, Acidisphaera and Aliidongia dominated in roots from the control sites. With the NGS method, it is possible to identify the microbiome of a whole root, while only a root fragment can be analysed by the Sanger method. These results extend the scope of knowledge on the preferences of certain groups of bacteria associated with truffles and their influence on the formation of ascomata in summer truffles. Our results may also be useful in selecting and monitoring sites that promote ascomata of Tuber aestivum.

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:
This study evaluates the influence of repeated artificial drought stress on the fine root charac- teristics – including ectomycorrhizae – of Norway spruce [Picea abies (L.) Karst]. The experimental site consisted of two plots in a mature spruce monoculture stand. The water regime at parts of both plots was regulated by shelters and an isolation trench during vegetation season (spring to autumn) since 2010. Root samples were collected during autumn in 2010, 2012, and 2013. Root analyses revealed the effect of drought stress on mycorrhizal root tips changed over time. While a density of active mycorrhizae was about 34% lower in drought-stressed areas compared to nonstressed (control) areas in 2010, it increased by 15% in 2012 and by 22% in 2013 over both plots. We observed the less pronounced effect of drought on a proportion of active mycorrhizae, but it generally followed the pattern of active mycorrhizae density. The density of nonactive mycorrhizae was not influenced by drought but significantly fluctuated during the course of the experiment. Other root characteristics such as the dry mass of fine roots (< 1 mm), the specific length of fine roots (< 1 mm) and the composition of the ectomycorrhizal community (primarily dominated by Amphinema byssoides, Tylospora fibrillosa, Tylopilus felleus, and Cenococcum geophilum) were also not significantly influenced by drought. Our results indicate the ability of Norway spruce fine roots to com- pensate for repeated drought stress of the intermediate intensity.

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.

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 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:
Ectomycorrhizas of Scots pine (Pinus sylvestris L.) and beech (Fagus sylvatica L.) were sampled in a mature forest ecosystem exposed for more than 40 years to moderate levels of gaseous and dust pollutants. Soil of the forest site was characterised by low pH and accumulation of heavy metals (Pb, Mn, Zn, Cu, Cd, Fe). Mycorrhizal vitality and enzyme activity of the root-surface and soil acid phosphatase (AcPase) were studied at 17 measurement points (0–5 cm soil depth) in relation to the content of inorganic phosphate (Pi) and aluminium ions (Al3+) in the soil. Anatomy of Scots pine and beech mycorrhizas taken from different measurement points was observed. The concentration of essential nutrients (C, N, P, Ca, Mg) and the ratios Ca/Al, Mg/Al and N/P were analysed in fine roots. High concentrations of Al3+ in the soil (40–118 meq kg-1) and low levels of Pi (12–44 mg P2O5 kg-1) were accompanied by high activity of the root-surface AcPase of pine and beech mycorrhizas (25–67 and 33–86 μmol pNP g-1 fresh weight h-1, respectively) and soil AcPase (6.8–22.4 μmol pNP g-1 dry weight h-1). The results indicate that fine tree roots are undoubtedly under stress as evidenced by a disturbance in P uptake and accumulation. However, the high vitality of mycorrhizas and the high Ca/Al ratio in fine roots suggest that the defence mechanisms of mycorrhizas and the rhizosphere are still able to ameliorate the influence of anthropogenic pollution.
Badania ektomikoryz sosny (Pinus sylvestris L.) i buka( Fagus sylvatica L.) prowadzono na Pogórzu Karpackim w dorosłym drzewostanie, który przez ponad 40 lat znajdował się pod wpływem gazowych i pyłowych zanieczyszczeń powietrza o średnich stężeniach. Gleby badanego ekosystemu leśnego cechowało niskie pH oraz znaczna akumulacja metali ciężkich (Pb, Mn, Zn, Cu, Cd, Fe). Badano zależność między stężeniem nieorganicznego fosforanu w glebie, a aktywnością enzymatyczną kwaśnej fosfatazy mikoryz i gleby. Analizowano także stężenia pierwiastków odżywczych (C, N, P, Ca, Mg) oraz jonów glinu (Al3+) w korzeniach drobnych. Mikoryzy sosny i buka były analizowane pod względem budowy anatomicznej oraz żywotności. Stwierdzono stosunkowo wysokie stężenie jonów Al3+ w glebie (40–118 meq kg-1) i niski poziom nieorganicznego fosforanu (Pi) (12–44 mg P2O5 kg-1). Jednocześnie zarejestrowano wysoką aktywność powierzchniowej kwaśnej fosfatazy mikoryz sosny i buka(odpowiednio, 25–67 i 33–86 μmoli pNP g-1 świeżej masy h-1) oraz kwaśnej fosfatazy gleby (6,8–22,4 μmoli pNP g-1 suchej masy h-1). Stężeniafosforu w korzeniach drobnych (poniżej stężeń uważanych za optymalne) oraz wysoki stosunek N/P pokazują, że pobieranie i akumulację fosforu przez systemy korzeni drobnych sosny i bukajest niedostateczne, mimo wysokiej aktywności kwaśnej fosfatazy. Budowa anatomiczna mikoryz, stosunkowo duży udział żywych mikoryz w systemie korzeni drobnych oraz wysoki stosunek Ca/Al w korzeniach sosny i buka(odpowiednio, 1,79 i 2,38) sugerują, że mechanizmy obronne mikoryz i mikroorganizmów ryzosfery mają zdolność łagodzenia wpływu zanieczyszczeń antropogenicznych.

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:
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.

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.

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.
