Controlled Rhizogenesis and Mycorrhization of Hazelnut (Corylus avellana L.) Cuttings with Black Truffle (Tuber melanosporum Vitt.)

Hazelnut (Corylus avellana L.) is commonly used as mycorrhizal host for Tuber melanosporum Vitt. (black truffle). Black truffle orchards have been established in and outside its natural distribution area, currently also in Chile. Hazelnut can be propagated rapidly by cuttings, which, however, may no...
