Abstract
A glasshouse experiment was conducted to observe the behavior of the artificial Tuber melanosporum-hazel symbiosis after outplanting in soil infected with the same Tuber species (104 spores cm−3 soil) or T. brumale (102 and 104 spores cm−3 soil). Despite a low level of Tuber-infection at planting, infection with T. melanosporum was maintained or increased, whereas infection by other mycorrhizal species remained low. In contrast, in non-inoculated control soil, infection with T. melanosporum declined and was almost completely replaced by other species. This investigation emphazises the importance of the intensity of T. melanosporum infection at planting. The effects of the diversity of mycorrhizal species and density of the soil fungal-inoculum, including indigeneous Tuber species on the spread of the introduced symbiosis after outplanting are reported. Intra- and interspecific competition for infection within the genus Tuber are discussed.
