Caracterización de micorrizas autóctonas en suelo y raíces provenientes de fincas ganaderas en Montecristi, República Dominicana
Among the main problems faced by Dominican livestock are: the poor quality of pastures, high costs of raw materials for the manufacture of concentrated feed and poor pasture management practices, among them there is no culture of fertilization of the pastures by producers. An alternative to improve pasture quality is mycorrhizal fertilization. This study was carried out in 12 grazing cattle farms in the Montecristi province, in the northwest of the Dominican Republic. A sampling was carried out in 12 cattle farms under grazing and the response variables of the number of spores and the percentage of mycorrhizal colonization were evaluated. The collection of the samples in each farm was in zig-zag. The spore isolation was done by the method of Gerderman and Nicholson (1963). For root staining, the method recommended by Phillips and Hayman (1970) was used. The presence of mycorrhizal fungi spores was found in the soil, as well as in the roots structures of the same were observed. Nine spore morphotypes were identified, of which three genera were characterized: Glomus, Acaulospora and Gigaspora. Using the Polymerase Chain Reaction (PCR) technique, the existence of the genus Paraglomus was determined.
