Alpha diversity indices. A) Number of observed AMF species (p-value 0.7073), B) Simpson index (p-value 0.94376) and C) Shannon’s Index (p-value 0.92697) of biodiversity detected in Bulk soil (Bs) and in soil associated with the roots of V. vinifera cv. Pinot Noir (Rs) at the two sampling times (1 S = flowering and 2 S = fruit development). Alpha diversity analysis was performed using the phyloseq package of MicrobiomeAnalyst, a free available on-line software (https://www.microbiomeanalyst.ca).
