Abstract

Asociaciones fúngicas de micorrizas y endófitos septados en gimnospermas del sur de la India Sólo un pequeño porcentaje de las asociaciones fúngicas de plan-tas que crecen en ambientes naturales han sido examinadas. Por ese motivo, nosotros examinamos asociaciones fúngicas de 15 gimnospermas del sur de la India. Todas estas plantas fueron colo-nizadas por micorrizas arbusculares y 7 de ellas fueron co-coloni-zadas por hongos endófitos septados Se cita por primera vez la presencia de asociaciones micorrizas arbusculares y endófitos septados en 10 y 5 gimnospermas, respectivamente. La coloniza-ción por micorrizas arbusculares caracterizadas por morfologías Paris e Intermedio se citan por primera vez para 11 especies de plantas. Se han asociado 6 esporas de micorrizas arbusculares, de los géneros Glomus, Claroideoglomus, Funneliformis y Scutellos-pora, a las rizosferas de gimnospermas. Palabras clave: Micorriza arbuscular, Ectomicorriza, Glomus, Hongos endófitos septados. Abstract Only a small percentage of plants growing in natural habitats are examined for their endophytic fungal associations. Therefore, we examined 15 gymnosperms growing in southern India for their en-dophytic fungal associations. All gymnosperms were colonized with arbuscular mycorrhizal fungi, of which seven had co-colonization by septate endophytic fungi. Presence of arbuscular mycorrhizal and septate endophytic fungal association has been reported for the first time in ten and five gymnosperms respectively. Arbuscular mycorrhizal colonization characterized by Paris-and intermedi-ate-type morphologies have been reported for the first time in 11 plant species. Six AM fungal spore morphotypes belonging to Glomus, Claroideoglomus, Funneliformis and Scutellospora were associated with the rhizospheres of the gymnosperms.
