“…The EcMF community detected in the nursery roots was relatively rich, which is in agreement with previous studies investigating fungi in nursery‐grown bare‐root coniferous as well as broad‐leaved trees (Leski et al , ; Menkis & Vasaitis ). However, Vosátka et al () proposed that these EcM species might be adapted to nursery conditions and their survival might be limited after outplanting or that their effects on the tree growth and fitness may be low.…”

An extensive field trial was established on a fly ash deposit (1) to evaluate whether the inoculation with arbuscular mycorrhizal fungi (AMF) and/or ectomycorrhizal fungi (EcMF) improves growth and survival of 13 planted tree species and (2) to trace the inoculated mycorrhizal fungi in tree roots after one growing season. Molecular methods were applied to characterize AMF and EcMF entering the studied system (inocula, native soil, and roots of nursery seedlings). Biometric parameters and mortality of the trees were recorded and the presence of AMF and EcMF in sampled trees was determined both microscopically and genetically. Mycorrhizal inoculation did not improve survival or growth of any tree species. Most AMF-host and all EcMF-host seedlings were highly precolonized already from the nursery. An abundant and diverse AMF community was also found in the field soil. The AMF inoculum taxa partially overlapped with AMF in the native soil and in the precolonized roots. After one season, the only two inoculum-unique AMF taxa were detected in host species non-precolonized or only partially precolonized from the nursery. The components of EcMF inoculum were not detected in any sampled tree. After the season, the ectomycorrhizal hosts maintained most of their original EcMF taxa gathered in nursery, some tree species were additionally colonized by EcMF probably originating from the soil. Our results show considerable self-restoration potential of nature on the target site. Mycorrhizal inoculation thus did not bring any conclusive advantage to the planted trees and seems superfluous for reclamation practice on the fly ash deposit.

“…In conclusion, as noted for beech and other forest tree species (Menkis et al 2005;Iwański et al 2006;Rudawska et al 2006;Leski et al 2008Leski et al , 2010Timonen and Kauppinen 2008), ECM fungal communities in forest bare-root nurseries are fairly diverse and the level of colonization of seedlings is very high. We therefore agree with the opinion of Southworth et al (2009) that artificial inoculation in general is not necessary in nursery practice.…”

“…We discovered 27 taxa of ECM fungi on 2-year-old beech seedlings from four bare-root nurseries. The number of recognized taxa was richer than for conifers (Scots pine, Norway spruce, and European larch) and small-leaved lime (Menkis et al 2005;Iwański et al 2006;Rudawska et al 2006;Leski et al 2008;Timonen and Kauppinen 2008), but comparable with pedunculate and sessile oak (Leski et al 2010) grown in nursery conditions. Taxa richness in individual nurseries ranged from 6 to 13, and is a characteristic feature of each nursery rather than a methodological bias causing underestimation.…”

“…Our findings add to the evidence of a growing number of symbionts being able to colonize seedlings in nursery conditions, and emphasize the elucidation potential of molecular tools for detailed descriptions of ECM communities in different environments. Some of the identified fungi (Cenococcum, Tuber, Hebeloma, Laccaria) have been previously noted in forest nurseries as ECM symbionts of coniferous (Menkis et al 2005;Rudawska et al 2006;Leski et al 2008;Menkis and Vasaitis 2011) or deciduous hosts (Leski et al 2010), but some of them have been found for the first time in nursery conditions (Hydnotrya, Hymenogaster, Lactarius), or even as mycorrhizal partners of European beech (Naucoria, Geopora). For more details about the detected ECM fungi, see Online Resource 3.…”

• Context An important feature of forest nursery management is the production of first-rate planting stock, which is closely connected with an adequate development of ectomycorrhizas on seedling roots. • Aims The aim of this study was to provide a detailed assessment of the ectomycorrhizal (ECM) fungal diversity of European beech grown in bare-root forest nursery conditions. • Methods Morphological and molecular analyzes were used to identify ECM fungi, quantify fungal richness, and record differences in the relative abundance of individual taxa. • Results Twenty-seven different mycorrhizal fungal taxa were found in four tested nurseries. Of these 27, only 6 were present in more than one nursery. Taxa richness in individual nurseries ranged from 6 to 13, indicating that ECM colonization potential is nursery-dependent. The most frequent taxa were: Tuber sp. 1, Cadophora sp., Cenococcum geophilum agg., Hebeloma sacchariolens, and Laccaria tortilis. According to the analysis of similarity, ECM fungal communities were significantly different between nurseries (R = 0.7741; p < 0.0001). • Conclusion Beech seedlings grown in bare-root nurseries are colonized by a highly diverse suite of ECM fungi; thus, artificial inoculation of seedlings is generally not necessary in nursery practice.

“…It is clearly seen that the contact type represented mainly by Wilcoxina mycorrhizas, well adapted to the nutrient rich conditions (Rudawska et al 2006;Leski et al 2008), correlates with higher nutrient availability (Fig. 5).…”

Abstract& Introduction In the present study, we describe the aboveground (epigeous sporocarps) and belowground (ectomycorrhizal root tips and their exploration types) composition of ectomycorrhizal (ECM) fungal species on three 20-year-old Scots pine sites. & Objectives The aim of this study was to relate the composition of ECM species to history of the site, stand density and soil chemistry (pH, toxic metal content, etc.) and to show how variable site condition contribute to above-and belowground ECM community changes. & Results ECM fungi were identified by combination of morphotyping and direct sequencing of the PCR-amplified internal-transcribed spacer of n-rDNA. By identifying sporocarps and mycorrhizas, we detected a total of 54 taxa of ECM fungi: 28, 30, and 23 species at the Kórnik (control), Luboń (near the chemical plant) and Głogów (near the Copper Smelter, heavy metal influenced) sites, respectively. The sporocarp survey weakly reflected the analysis of ECM tips in terms of species composition, and largely supplemented the belowground view. Wilcoxina rehmii was the belowgrounddominating species at all three sites and was found at the highest abundance at the site established after the clear cut of poplars and with the highest tree density (Kórnik). At the Luboń site, subdominant mycorrhizas were formed by Phialophora finlandia. On the site near the Copper Smelter in Głogów, a significant shift in species composition was observed compared with the two other sites and a very large proportion of medium-fringe exploration type belonging to Atheliaceae was found. Despite the partial overlap in the nonmetric multi-dimensional scaling ordination, analysis of similarity revealed significant differences between tested sites. & Conclusion Because of the number of covarying site properties which may influence ECM communities, it is difficult, if not unfeasible, to separate the precise reasons of the distribution of ECM fungi. Continued research on the biodiversity of ECM fungi in field sites along an environmental gradient would greatly improve our understanding of the effects of ecological conditions on the functional diversity of mycorrhizal fungi.
