abstract：:In field conditions, grapevine roots normally are colonized by arbuscular mycorrhizal fungi (AMF). However, little is published, from either morphological or molecular studies, on the species composition of these symbionts in production vineyards. The AMF biodiversity of two Piedmont vineyards (at Neive and Lessona), ...
