Abstract

[Autom. eng. transl.] The consumption of hazelnuts is growing strongly. In Italy it has reached over 140,000 t / year, only partly covered by national production. Faced with these data, the cultivation of the hazel is becoming increasingly important even in areas that are not traditionally suited, as a valid crop alternative to the crisis of other species both from fruit and herbaceous. This choice must include a careful assessment of the adaptability of the varieties so far spread in the various cultivation environments, taking into account sustainability aspects, including the economic one. One of the emerging and most interesting technologies in the field of agro-sustainability is the use of symbiotic microorganisms and in particular of mycorrhizal fungi. The mechanism of action of these fungi consists in creating surfaces of nutritional exchange with the host, in which the mycorrhiza absorbs nutrients from the ground that are not very mobile to give them to the plant and receive photosynthes (sugars in the first place) in exchange. The mycorrhizal fungus forms a vast extra-radical mycelial network that allows you to explore a much greater volume of soil than the root can do on its own, significantly increasing the amount of water and nutrients that can be reached. In the arbuscular mycorrhizas, the intra-radical hyphae produce small branched structures of short life, called arbuscles, responsible for the nutritional exchanges between the two symbionts, while the extra-radical hyphae have the function of absorption of nutrients and phosphorus in particular, whose availability it is reduced in soils with acid and alkaline pH due to the phenomenon of retrogradation.
