An analysis of the climatic parameters needed for Tuber melanosporum cultivation incorporating data from six continents

Climatic parameters associated with sites producing Tuber melanosporum fruiting bodies within countries that have a natural population of Tuber melanosporum and those without such records were compared. Represented continents include Africa, Asia, Australia, Europe, North America and South America with only Antarctica remaining outside the scope of this study. The compiled data presents a broader than expected range of climatic parameters that are suitable for truffle cultivation. Development of fruiting orchards in countries that do not have a history of natural populations has expanded our understanding of the suitable climatic ranges of this species. Truffle cultivation is successful in areas that have a lower temperature and higher rainfall levels than expected. The data compiled here is of use to truffle scientists as well as cultivators in choosing suitable locations for a plantation.
