Abstract
Incorporating biofertilizers, such as arbuscular mycorrhizal fungal (AM fungi) inoculants, into vineyard management practices may enhance vine growth and reduce environmental impact. Here, we evaluate the effects of commercially available and local AM fungal inoculants on the growth, root colonization, and nutrient uptake of wine grapes (Vitis vinifera) when planted in living field soil. In a greenhouse experiment, young wine grapes were planted in field soil and inoculated with either one of three commercially available mycorrhizal inoculant products, or one of two locally collected whole soil inoculants. After four months of growth, inoculated vines showed no differences in plant biomass, colonization of roots by AM fungi, or foliar macronutrient concentrations when compared to uninoculated controls, but vines grown with local inoculants had greater shoot biomass than vines grown with commercial mycorrhizal inoculant products. This suggests that inoculations with AM fungi may not improve young vine performance in field soils with a resident microbial community, and effects seen from inoculations on vine growth can vary by inoculant type and source. This study revealed that despite disturbance, the effects of microbial communities found in field soil can outweigh effects seen from AM fungal inoculants. However, local whole-soil inoculants may provide more plant growth benefits than commercially available inoculants.
