摘要
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 brines associated with Pinus spp. versus Quercus spp. %26lt;br%26gt;Area of study: We studied the natural habitats of T. aestivum in the Alto Tajo Nature Reserve in central Spain. %26lt;br%26gt;Material and methods: During 5 years, we monitored the production of carpophores and brine size of 145 T aestivum brides 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. %26lt;br%26gt;Main results: The size of brines associated with Pinus was significantly smaller than that of brines associated with Quercus. However, carpophore production per brine, and especially for brines of similar size, was greater when the host plant was a pine. After accounting for brine size, the production of brines 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 brines associated with Quercus faginea and Q. ilex subsp. ballota, respectively. %26lt;br%26gt;Research highlights: The considerable ability of Pinus nigra subsp. salzmanni and P sylvestris to form effective brines 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.
