“…This fact suggests that P. nigra subsp. salzmannii may better tolerate increases in soil pH and/or exchangeable calcium that occurs inside Tuber brûlés, as proposed by García-Montero et al (2009.…”

“…As a result, the truffle production of brûles of the same size was much greater in pines (2.23 and 1.61 times greater) that than the production in oaks. García-Montero et al (2009 hypothesized that the ecological significance of the brûlé is to modify the soil environment, increasing active carbonate and exchangeable calcium and/or soil pH, to stress the host plant with nutritional deficiencies by lime induced chlorosis. The plant would respond to the stress by increasing the number of root tips and, therefore, favoring Tuber spp.…”

Natural production of Tuber aestivum in central Spain: Pinus spp. versus Quercus spp. brûlés

Aim of study: Tuber aestivum is the most widespread edible truffle, with increasing commercial interest. This species can produce carpophores with conifer hosts, in contrast with the inability of Pinus spp. to induce fruiting in other truffle species such as Tuber melanosporum. Therefore the objective is to compare the characteristics and carpophore production of T. aestivum brûlés associated with Pinus spp. versus Quercus spp.Area of study: We studied the natural habitats of T. aestivum in the Alto Tajo Nature Reserve in central Spain. Material and methods:During 5 years, we monitored the production of carpophores and brûlé size of 145 T. aestivum brûlés associated with Pinus nigra subsp. salzmanni and P. sylvestris and Quercus ilex subsp. ballota and Q. faginea hosts. Statistical treatment was performed using the Statistica Program v. 6.Main results: The size of brûlés associated with Pinus was significantly smaller than that of brûlés associated with Quercus. However, carpophore production per brûlé, and especially for brûlés of similar size, was greater when the host plant was a pine. After accounting for brûlé size, the production of brûlés associated with Pinus spp. was 2.23 (95% CI, between 1.35 and 3.69) and 1.61 (95% CI, between 1.02 and 2.54) times greater than the production of brûlés associated with Quercus faginea and Q. ilex subsp. ballota, respectively.Research highlights: The considerable ability of Pinus nigra subsp. salzmanni and P. sylvestris to form effective brûlés and to produce carpophores of Tuber aestivum in natural conditions was clearly demonstrated, and suggest that those species can be of use in the culture of T. aestivum.

“…Tuber mycorrhizal activity, mycelium growth and carpophore production take place inside the brülé, mainly behind the brülé line (Callot, 1999). Some authors have explained the production and development of brülés (Granetti et al, 2005;Sourzat, 2004) but others have indicated that the ecological conditions relating to brülés are yet to be clarified García-Montero et al, 2009, 2014aRicard, 2003). There is virtually no reference to the possible effects of Tuber species on soil fauna.…”

“…As with ECM mats, García-Montero et al (2009) indicated that Tuber brülés can also alter soil biogeochemistry and some authors described how T. melanosprum brülés decreaseTOC in internal soils in relation to external soils (Callot, 1999;García-Montero et al, 2014a;Granetti et al, 2005;Ricard, 2003). In calcareous Mediterranean áreas, García-Montero et al (2014b) indicated that T. aestivum significantly increases soil pH and significantly decreases total carbonate in the internal soils of brülés compared to external soils.…”

“…Conversely, Sourzat (2001) and Jaillard et al (2008) found truffles grown on acidic soils (on granite or gneiss) whose upper horizons were carbonated by human practices and had less than 20 g active carbonate kg -1 of soil. These data led some authors (Jaillard et al, 2007(Jaillard et al, , 2008García-Montero et al, 2007a, 2009a to assume that the presence of active carbonate is critical for truffle production, even if it is in small amounts.…”

Aim of study: The program "Typology of truffle stations in the Pyrenean Regions" aimed to define the ecological conditions and culture practices that favor Tuber melanosporum growth and fruiting in this area.Area of study: Navarra, Catalonia, Midi-Pyrénées and Languedoc-Roussillon.Material and methods: The program was based on the survey of 212 wild and cultivated truffle beds of evergreen oaks (Quercus ilex). The data collected in the field consisted of photographs, samples of soil, roots and mycorrhizae, and information on cultural practices followed by truffle growers.Main results: (i) truffle soils are alkaline, from neutral, dolomitic, to moderately or very calcareous soils; (ii) truffle soils are light, well-structured and stable to water immersion; (iii) mycelium that colonizes roots survives in suboptimal conditions, but it does not necessarily bear ascocarps. Finally our results suggest that T. melanosporum is a relatively ubiquitous fungus able to grow, or at least to persist, in a wide range of physical and chemical soil conditions. We propose a probabilistic model of the environment favorable for fruiting, built around a two-dimensional graph with an axis for the chemical conditions, like soil alkalinity, and another axis for the physical conditions, like soil structure. Research highlights: Soil alkalinity and structure allow to built a convenient representation of the ecological capacity of a place to be good T. melanosporum habitat, and thus of the probability for truffle growers to harvest truffles according to the environmental properties of their truffle orchards.Keywords: dolomite; limestone; mycorrhizae; Quercus ilex; field survey; Tuber melanosporum.
