“…Studies on wild sporocarp production of edible Boletus have been carried out in different environmental situations (Rondet and Leprince 2001, Martí-nez 2003, Salerni and Perini 2004. Controlled cultivation and mycorrhizal synthesis studies with Boletus are relatively abundant (Pantidou 1961(Pantidou , 1962(Pantidou , 1964Tozzi et al 1980Tozzi et al , 1981Molina and Trappe 1982b;Poitou et al 1982;Ceruti et al 1983Ceruti et al , 1985Poitou and Mamoun 1984;Zucherelli 1988, Meotto andPellegrino 1989).…”

Field ectomycorrhizae sampled under Boletus edulis and Cistus ladanifer have been characterized and described in detail based on standard morphological and anatomical characters. The described ectomycorrhiza has traits typical of Boletales: whitish with three differentiated plectenchymatous layers in the mantle in plan view forming ring-like structures and rhizomorphs with highly differentiated hyphae. The inflated, smooth cystidia-like clavate end cells on the surface of the rhizomorphs and their slightly twisted external hyphae are additional characterizing features. The Hartig net occupies 1K rows of cortical cells, partly reaching the endodermis. Not all hyphae have clamps. The identification of the fungal symbiont as B. edulis was confirmed by ITS rDNA sequence comparison between mycorrhizas and sporocarps. The singularity of this symbiotic association, as well as its ecological and practical implications, are discussed.

“…The Shannon diversity index, which takes into account the sporocarp occurrence of a given species as well as number of taxa (O'Dell et al 2004) was significantly lower in the CT than in the no-tillage treatments NV, NP and NIP (Shannon Diversity t-test; P \ 0.05; PAST). The higher diversity of sporocarps in the NIP treatment, as also abovementioned for total productivity, can be explained by the increase in water availability in irrigated plots, given the strong influence of moisture on development of fungal fruiting bodies (Wiklund et al 1995;O'Dell et al 1999;Salerni and Perini 2004). The lowest diversity and abundance of fungal sporocarps in the CT treatment are expected since many soil fungi are mainly abundant in the organic layer present on the upper soil surface layers.…”

Chestnut plantations for fruit production in Northern Portugal have been subjected to intensive management system, including soil tillage, mineral fertilization and pruning. Some of these practices have no positive effect on productivity and soilplant-water relations. Other systems (e.g., no tillage with maintenance of grass cover) have been adopted, aiming a multifunctional land use, exploiting nuts, pasture and edible mushrooms. Thus, an experimental trial was installed to assess the effects of such systems on productivity, sustainability and annual net income, as compared with the conventional system, over a six-year period. The treatments were: conventional soil tillage (CT); no tillage with permanent spontaneous herbaceous vegetation cover (NV); no tillage with permanent rainfed seeded pasture cover (NP); and as NP but with irrigation (NIP). Production of nuts, forage and edible mushrooms were measured and sustainability was assessed by production and diversity of fungal sporocarps. Annual net income was estimated by the difference between the annual gross outputs (market values for nuts, forage and edible commercial mushrooms) and the annual input costs. The greatest nut and edible mushroom production and sporocarp biodiversity were achieved in the NIP and NV and the smallest in the CT treatment. The highest annual gross output was estimated for the NV and NIP treatments, whereas the highest annual net income was obtained for the NV. No tillage with maintenance of spontaneous grass cover showed to be the most favourable management system, as it has increased productivity and biodiversity.

“…Obtaining B. edulis mycorrhizae in C. ladanifer plants is a relevant first step toward achieving commercial plantations for early production of B.edulis sporocarps, particularly at a time when wild production of this species is likely to decline each year as a result of overexploitation and lack of regulation of this natural resource (Salerni and Perini 2004). Developing an efficient protocol of controlled mycorrhization is critical to enable the use of an ectomycorrhizal fungus species in forestry (Guerin-Laguette et al 2000).…”

Boletus edulis Bull. is one of the most economically and gastronomically valuable fungi worldwide. Sporocarp production normally occurs when symbiotically associated with a number of tree species in stands over 40 years old, but it has also been reported in 3-year-old Cistus ladanifer L. shrubs. Efforts toward the domestication of B. edulis have thus focused on successfully generating C. ladanifer seedlings associated with B. edulis under controlled conditions. Microorganisms have an important role mediating mycorrhizal symbiosis, such as some bacteria species which enhance mycorrhiza formation (mycorrhiza helper bacteria). Thus, in this study, we explored the effect that mycorrhiza helper bacteria have on the efficiency and intensity of the ectomycorrhizal symbiosis between C. ladanifer and B. edulis. The aim of this work was to optimize an in vitro protocol for the mycorrhizal synthesis of B. edulis with C. ladanifer by testing the effects of fungal culture time and coinoculation with the helper bacteria Pseudomonas fluorescens Migula. The results confirmed successful mycorrhizal synthesis between C. ladanifer and B. edulis. Coinoculation of B. edulis with P. fluorescens doubled within-plant mycorrhization levels although it did not result in an increased number of seedlings colonized with B. edulis mycorrhizae. B. edulis mycelium culture time also increased mycorrhization levels but not the presence of mycorrhizae. These findings bring us closer to controlled B. edulis sporocarp production in plantations.
