Abstract

The arbuscular mycorrhizal fungi are represented in all soils and colonize more than 80 % of terrestrial plants. His association depends on many factors edaphoclimatic, plant and fungus. In rice cultivation mycorrhizal symbiosis was reported under anaerobic conditions. That is why the research was conducted in order to evaluate the response in rice plants inoculated with different strains of arbuscular mycorrhizal fungi (Claroideoglomus claroideum, Glomus cubense, Rhizoglomus intraradices y Funneliformis mosseae) in flooded soil conditions Hidromórfico Gley Nodular Ferruginoso Petroférrico, with a water depth 5 cm in the Scientific Technological Base Unit “Los Palacios”. The results demonstrate that rice colonized, even with low percentages due to the presence of the water layer, which affects the establishment of the fungus in the plant. As for height, tillering, dry mass of the aerial part and roots in rice plants they increased when inoculated with different strains than the control uninoculated observed a symbiotic efficiency higher depending on tillering and dry mass of the aerial part with strains R. intraradices, G. cubense and C. claroideum, but always strains R. intraradices and G. cubense were among the strains of inoculum of HMA that showed greater effect on plant development. These results suggest the use of these strains in the production of bio-fertilizers for rice cultivation.
