520			_aVariations in Glomeromycota species composition in a wheat crop under different tillage systems. Agricultural practices affect the dynamics and biodiversity of Glomeromycota. Field experiments were carried out in order to assess the variations of the arbuscular mycorrhizal fungi community in a wheat crop, which was evaluated at different phenological stages under different tillage systems (conventional tillage and no-tillage) and nitrogen fertilization during 2 years. We found 24 species, which is considered a high number in contrast to other studies in agroecosystems. The species belonging to the family Glomeraceae showed a higher dominancy, especially in no-tillage. The lack of tillage in this system did not promote a higher specific richness or evenness in the distribution of Glomeromycota, as other researchers have pointed out, but in contrary the opposite tendency was found.
