In avocado plants, nursery phase, a study to evaluate the colonization with arbuscular mycorrhiza fungi (FMA) formers, using three different soils coming from orchard located at the eastern plains of Colombia was conducted. The objective was to determine the established colonization type using two native strains. Two morphotypes of FMA belonging to the genera Glomus and Acaulospora were isolated and identified and inoculated in three varieties of avocado Lorraine, Santana and Common. It was determined that the predominant colonization for both morphotypes was the Paris form. The highest colonization percentage was obtained in the Common avocado variety, inoculated in a Haplodux type soil with the Glomus isolation.

Keywords : Fungi mycorrhiza formers; acidic soils; colonization type; potential microbial infectivity.
