We evaluated the mycorrhizal status of Jacaratia mexicana A. DC. and the presence
of arbuscular mycorrhizal fungi (AMF) in three patches of dry deciduous forests located on
the slope of the Gulf of Mexico. There were no mycorrhizal structures in any of the materials
collected in field, and therefore the susceptibility of this specie to AMF was determined. The
study revealed the presence of arbuscles and vesicles 15 days after inoculation. Six
morphospecies were identified: Glomus intraradices, G. constrictum, G. sinuosum, Glomus
sp. 1, Glomus sp. 2. and Entrophospora infrequens. The only related morphospecies in
sampled sites were G. intraradices and G. sinuosum, and they were also fairly abundant in
Veracruz (8, 870 and 5), Campeche (958 and 448) and Yucatán (3,708 and 16). All of them
have not been reported associated with J. mexicana in our country before.
