Antecedentes: Los hongos micorrízicos arbusculares (HMA) forman asociaciones simbióticas con la mayoría de las especies vegetales, por lo cual es importante conocer la riqueza, diversidad y funcionalidad de estas especies de HMA.Objetivo: Determinar la composición y abundancia de esporas de HMA asociados a la rizosfera de Agave cupreata en la época seca y de lluvia en regiones mezcaleras de Michoacán. Métodos: En dos épocas se muestreó suelo rizosférico de A. cupreata en ocho sitios; parte de los suelos de cada sitio se usó para la propagación de HMA. Las esporas de los HMA se identificaron taxonómicamente con base en su morfología, por sitio, época de muestreo y maceta de propagación.Resultados y conclusiones: Se encontraron 39 morfo-tipos de HMA. Las familias Glomeraceae y Acaulosporaceae registraron la mayor abundancia de morfo-tipos, 37 y 34%, respectivamente. Acaulospora scrobiculata, A. spinosa y Glomus deserticola se encontraron en todos los sitios de muestreo; Rhizophagus intraradices sólo se detectó en las macetas de propagación. El 29% de los morfo-tipos sólo se encontró en la época seca, el 16% en la época de lluvia y el 55% en ambas épocas de muestreo; en las macetas se propagaron sólo el38% de los morfo-tipos.

Glomus Deserticola

Rhizosphere modification through root exudation is an important attribute that regulates not only the availability of nutrients in the soil but also their acquisition by plants. To test the above, 10-year-old Kinnow mandarin plants budded on Troyer citrange were inoculated with arbuscular mycorrhizal fungi (AMF) (Glomus deserticola) and Azotobacter chroococcum in different combinations with organic-farm-yard manure (FYM) and inorganic fertilisers in February when the root system was active. Plants with FYM alone were treated as a control. In the present investigation, a higher release of organic acids such as malic, citric, shikimic, and fumaric acids was evident from symbiotic roots of Kinnow inoculated with AMF (G. deserticola). Soil pH decreased significantly from 8.5 before the start of the experiment to 6.4 at the end of the experiment in the treatment where G. deserticola was applied with FYM. A decrease in soil EC and organic carbon, and an increase in soil availability of N, P, and K, leaf nutrient status, and fruit yield and quality were observed when the plants were inoculated with G. deserticola compared with all other treatments. This study indicates that G. deserticola, when compared with A. chroococcum, modifies the rhizosphere favourably to improve soil nutrient availability and consequent uptake by plants and thus result in better growth, fruit yield, and quality of Kinnow.

Glomus Deserticola

In this study the possibility of using a biostimulant based on Glomus deserticola to improve the growth and quality of Gasteraloe plants and protection against Fusarium sp. was evaluated. Objectives of the work were: i) use Glomus deserticola to assess whether the use of this Arbuscular mycorrhizal fungi can increase the growth rate of Gasteraloe plants generally slow in their growth cycle; ii) consider if the use of Glomus deserticola can lead to an increase in plant resistance under saline substrate conditions; iii) evaluate how the use of Glomus deserticola allows greater protection of plants from Fusarium sp. which often affects the roots of these succulents. The four experimental groups in cultivation were: i) group without Glomus, irrigated with water and substrate previously fertilized; ii) group without Glomus, irrigated with salt water (0.50 g of NaCl Kg-1 dry soil) and substrate previously fertilized; iii) group with Glomus deserticola, irrigated with water and substrate previously fertilized; iv) group with Glomus deserticola, irrigated with salt water (0.50 g of NaCl Kg-1 dry soil) and substrate previously fertilized. The test showed a significant increase in agronomic parameters analyzed in plants treated with Glomus deserticola on Gasteraloe cv. Magica and Gasteraloe aristata x platinum. The test also highlighted how the use of mycorrhizae in particular of Glomus spp. can determine a greater resistance against salt stress and greater protection against attacks of Fusarium sp. The application of mycorrhizae in the cultivation of succulent plants guarantees growers the possibility of obtaining a superior quality product, greater resistance to biotic and abiotic stress, an increase in the growth rate and mineral content of the tissues, aspects that are then found in the improvement of the quality of the plants and consequently their commercialization.
