Ecological Studies on Truffles (Tuber Spp.)

Truffles are naturally distributed in the region of North Temperate and Frigid Zore in Western Europe relied on the environmental conditions,such as climatic characteristics and soil properties.Solils with limestone formations known as `Scaglia rossa'are the typical type for the growth of truffles,which usually produce a `burned'area around their symbiotic plants as a result of phytotoxic action by volatile substances released from turffle sporophores.Trees of genera Quercus,Fagus,Alnus,Castanea,Abies etc are the most common hosts to be associated by truffles in Europe.Some Chinese truffles, such as T.indicum,T.sinense and T.xizangense,present in mixed forests of Pinus and Quercus.Trees of genera Alnus,Coriavia and Rhododendron are also considered to have relationships with truffles in China.Dynamics of fungal and bacterial populations of the rhizosphere of some truffle-producing trees were discussed in this paper,Experimental results supported the hypothesis that the truffle ascocarps become autonomous at some stage in its development.
