La creciente demanda de Stevia rebaudiana Bertoni como edulcorante natural, exige la búsqueda de sistemas de producción más sostenibles. El fósforo es indispensable en este cultivo, al estar involucrado en procesos de transformación de energía y biosíntesis de fitoquímicos; su poca disponibilidad afecta la producción y retarda el crecimiento de las plantas. La simbiosis con hongos micorrícicos arbusculares (HMA) representa una vía sostenible para aumentar la producción de los cultivos, gracias a una mejor absorción de nutrientes, particularmente fósforo. El objetivo de este estudio fue evaluar el efecto de consorcios de HMA nativos, provenientes de las localidades: Reserva Cuxtal (RC), Tizimín (TZ) y Colonia Yucatán (CY) pertenecientes al estado de Yucatán, en interacción con porcentajes de fósforo en base a su requerimiento nutricional, sobre parámetros de crecimiento y fotosíntesis en S. rebaudiana a nivel invernadero. Se utilizó un diseño completamente al azar con arreglo bifactorial 4 X 5. Los resultados indicaron que, a bajas concentraciones de fósforo, hay mayor colonización micorrícica. Los tratamientos RC+25 % P y CY+25 % P aumentaron el crecimiento, mejoraron la arquitectura aérea de las plantas y la producción de biomasa, derivado de un mayor contenido de clorofila y mejor tasa fotosintética con respecto a plantas no inoculadas.
L Objective: Stevia rebaudiana Bertoni is a crop that can meet the demand for natural sweeteners; however, this demand requires a sustainable production, as a result of the inclusion of its steviol glycosides or active ingredients in the food and pharmaceutical industries. Design/methodology/approach: Modern agriculture implies the integrated use of valid natural resources, such as the arbuscular mycorrhizal fungi (AMF). These microorganisms establish a symbiotic relationship with, at least, 80% of the plants, to which they provide multiple benefits. They can directly and indirectly improve crop productivity, through nutrient (particularly, phosphorus) translocation of the soil solution. Results: As a sustainable alternative for the production of S. rebaudiana, they improve its nutritional state, resulting in a higher biomass production and glycoside concentration —fundamental yield parameters. Additionally, they promote resistance to biotic and abiotic stress factors and improve soil quality. Limitations/implications: It is worth mentioning that this fungi-plant mutualism is approximately 400 million years-old; however, it has only aroused interest during the last few years. Findings/conclusions: Although arbuscular mycorrhizal fungi (AMF) are an exploitable resource, their communities are threatened by biotic factors —such as the interaction with other microorganisms— and abiotic factors —which involve bad agricultural practices.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
