Cultivation Practices

The highly prized black truffle (Tuber melanosporum) has become a model species for ectomycorrhizal fungi biology. However, several questions concerning its reproductive phase remain unanswered. To provide new hypotheses on the fruitbody formation process, we have explored the causal links among development characters of black truffle fruitbodies that are primarily linked to either the mating process, fruitbody growing stage, or maturation. Path analysis was applied to test causal models outlining the relationships among fruitbody development characters such as fruiting depth, weight, shape, and spore maturity. These characters were investigated over a two-season survey and three soil typologies (plus peat-based substrate) under irrigated conditions. We found a clear and generalized relationship between fruitbody weight and shape. Among clusters of fruitbodies we found a positive relationship between the weight of the largest fruitbody and the weight of the remaining fruitbodies. However, no generalized relationships among characters linked to different development stages appeared. Our results were noticeably consistent across soil typologies, both for fruitbodies growing singly and in clusters, indicating that early-developing fruitbody characters did not influence characters linked to subsequent morphogenetic stages. The lack of links among stages opens new perspectives for pre-harvest quality management with stage-specific cultivation practices.

Collective Influence

Although soil is one of the factors in the biology of Tuber melanosporum (black truffle of Périgord), which has been the subject of much study, there are few quantitative analyses relating to its effects on carpophore production. The aim of this work is to establish the statistical relationship between T. melanosporum productivity in 20 soil surface horizons and their conventional soil properties (granulometric texture, pH, calcareous fractions, organic carbon, total nitrogen, exchangeable cations). The study area is situated in the centre of the Iberian Peninsula under a Mediterranean climate. Statistical analysis shows that the collective influence of these conventional soil features is low, as principal component analysis explains only 27% of the variance in T. melanosporum production. However, a high percentage of active limestone (calcium carbonate extractable with ammonium oxalate) accounts for 40% of the variance in T. melanosporum production. Active limestone is very important to T. melanosporum because it regulates soil pH and exchangeable Ca2+ availability and participates in the organisation and maintenance of the soil structure; it also plays a role in the truffle’s nutrition. These results obtained for active limestone may be of use in truffle cultivation.

Total Market

There are about 2500 recorded species of edible mushrooms. The most expensive and sought after of these mushrooms belong to the mycorrhizal group and include Tuber melanosporum Vitt. (Périgord black truffle), Tuber magnatum Pico & Vitt. (Italian white truffle), Tricholoma matsutake (Ito & Imai) Sing. (matsutake), Boletus edulis Bull: Fr. sensu lato (porcini) Cantharellus cibarius Fr.: Fr. (chanterelle), and Amanita caesarea (Scop.: Fr.) Pers: Schw. (Caesar's mushroom). The total market for these is measured in billions of US dollars. Over the past 100 years, harvests of many mycorrhizal mushrooms have declined dramatically, which has prompted interest in the development of methods for their cultivation. So far only a few species of truffles have been produced in commercial quantities, although methods have been developed that may see the cultivation of species such as Cantharellus cibarius, Lyophyllum shimeji (Kawam.) Hongo, and Lactarius deliciosus (L.: Fr.) Gray. Despite this, many of the most expensive mycorrhizal mushrooms, including Tuber magnatum Pico & Vitt. and Tricholoma matsutake, have defied cultivation. Our paper will attempt to highlight possible reasons why mycorrhizal mushrooms have proven to be so difficult to grow and how we might better manage mycorrhizal mushroom forests to sustain natural production.Key words: edible, ectomycorrhiza, mushroom, truffle.
