Soil management, in terms of tillage and cropping systems, strongly influences the biological properties of soil involved in the suppression of plant diseases. Fungistasis mediated by soil microbiota is an important component of disease-suppressive soils. We evaluated the influence of different management systems on fungistasis against Fusarium graminearum, the relationship of fungistasis to the bacterial profile of the soil, and the possible mechanisms involved in this process. Samples were taken from a long-term experiment set up in a Paleudult soil […]

The high availability of metallic ions in the soil, including Mn2+, may inhibit arbuscular mycorrhizal fungi (AMF), slowing down spore germination and, consequently, the mycorrhiza formation, therefore decreasing the symbiotic effectiveness. The aim of this study was to evaluate the effect of Mn2+ ions on spore germination in six AMF species of the genera Glomus, Acaulospora, Gigaspora and Scutellospora under in vitro conditions. Different Mn2+ doses (15, 30 and 75 mg kg-1) as MnCl2.4H2O were added to a washed sand […]
