Resumen:
In the Mexican economy, and especially in the Soconusco region of Chiapas, coffee is economically important, and sustainable management most cover pests and diseases. In this study, we searched for native arbuscular mycorrhizal fungi (AMF) that could be used as biofertilizers in coffee cultivation. We collected 21 soil samples from seven coffee plantations (Coffea canephora) in November 2015. We used wet sieving and decanting to quantify abundance, richness and composition of morphospecies, as well as their relationships with soil properties. A total of 20 morphospecies and five new records of AMF were obtained, and the most frequent genera were Acaulospora and Glomus. The Toluca and Victoria sites had more morphospecies richness (17 spp. each) than San Agustín, November 20 and San Luis Nexapa (4-7 spp. each). Providencia and Platanar were intermediate but had the highest spore abundance. The dissimilarity of Victoria and Toluca may reflect a low concentration of PO4 -3 in the soil. P availability, linked to soil acidity, sems to be regulating these mycorrhizae communities at Soconusco. AMF consortia specific for soil P-levels and acidity, i.e. Acaulospora and Glomus consortia, may occur and be common in the environmental conditions of Mexican coffee plantations, Strains should be tested for compatibility and functionality before using them as native biofertilizers. © 2018, Universidad de Costa Rica.
