MYCORRHIZATION OF CORYLUS AVELLANA L. AND QUERCUS ROBUR L. SEEDLINGS WITH TUBER AESTIVUM VITTAD

Mycorrhization could be a valuable tool in order to produce a remarkable and a high economical interest mushroom. Corylus avellana L. and Quercus robur L. are known as mycorrhizal hosts for Tuber aestivum Vittad. (Truffle). Cultivating truffles, is important to know the necessary pH level of the soil, on which the mycorrhization occurs. The selected tree species are known to have a high percentage of inoculation level under the effect of truffle spore inoculum. In the study, seedlings of the previously mentioned species were subjected to truffle infection at three soil pH levels (7.3, 7.5, 7.7). During the experiment two different weight of truffle and two inoculation methods (soil-inoculation and inoculation with suspension) were tested. Our results show that significant changes were obtained at 7.5 pH level, when the weight of the truffle added to the roots influenced the mycorrhization level in a positive way, and also inoculation method significantly influenced the T. aestivum appearance. In conclusion, our data suggests that Common hazel and European oak mycorrhization occurred, yet it is important to ensure the necessary growth requirements for a greater and higher quality production of truffles.
