Background: Edaphic properties influence the abundance of spores and the colonization of arbuscular mycorrhizal fungi, however, there are few studies of the properties that have a greater impact on arbuscular mycorrhiza in the dry and rainy season in banana crops.
Objectives: To determine the influence of edaphic properties on the abundance of spores and the colonization of mycorrhizal fungi in banana plantations in two seasons of the year.
Methods: Soil and banana roots were collected in Tecoman, Colima, and the influence of edaphic properties on the abundance of spores and colonization of mycorrhizal fungi was determined by principal component analysis.
Results and conclusions: The highest value of spore abundance (1700 spores/100 g of soil) and colonization of mycorrhizal fungi (63.3 %) were found in the rainy and dry season, respectively. Twenty three morphotypes of the Claroideoglomus, Acaulospora, Rhizophagus, Racocetra, Funneliformis, and Glomus genera were identified, the latter being the most common. The edaphic properties that promote or reduce the abundance of spores and colonization of AMF differ in each season, with a greater number of factors that influence the abundance of spores.
