The main objective of the project is to understand the positive role of AMF in improving the fitness of Riesling and Pinot Blanc vines under drought conditions. Initially, a pot trial will be conducted to test the efficiency and positive effect of three AMF bioproducts on three vines under low-water conditions and using two different soils from two vineyards in the Rheingau (WP1). Parallel to WP1, the Institute for Grapevine Breeding at Hochschule Geisenheim University will graft the three rootstocks used in WP1 with the Riesling and Pinot Blanc scions (WP2). This will allow us to select from the pool of grafted plants those with the best performing and AMF-compatible rootstocks to be used in the subsequent field (WP3) and greenhouse (WP4) trials. The field trial will be conducted in two different vineyards in the Rheingau, which are characterized by different soil types and topography. WP3 will give us the opportunity to test under real field conditions the compatibility and effectiveness of AMF on Riesling and Pinot Blanc grafted plants in two different vineyard ecosystems. The additional greenhouse experiment (WP4) will be conducted in rhizoboxes to evaluate in detail the AMF compatibility and the positive effect of the AMF inoculum and the type of grafted plants not only on plant fitness and development, but also on various soil/plant properties, such as soil microbiome structure, root exudates, root architecture and edaphic properties.
