Description
Abstract
La actividad microbiana de la rizosfera es, en gran medida, responsable del funcionamiento
del ecosistema y de la fertilidad de los suelos agrícolas. Entre los microorganismos benéficos del
suelo, tanto los hongos formadores de micorrizas arbusculares (MA) como las bacterias rizosféricas
promotoras del crecimiento (BRPC), constituyentes claves de la zona rizosférica, contribuyen
a mejorar el desarrollo y la nutrición de la planta, así como a incrementar la tolerancia de los
cultivos frente a determinadas situaciones de estrés de tipo biótico o abiótico. La integración de
estos microorganismos en los sistemas garantizan la sostenibilidad, contribuyendo a optimizar la
calidad y la salud del suelo, limitar el aporte de nutrientes e incrementar los rendimientos. En el
presente capitulo, se resumen los avances en el manejo de estos microorganismos rizosféricos en
los agrosistemas de Canarias, así como algunos resultados de los efectos de su aplicación durante
las primeras fases del cultivo, sobre diferentes especies de interés agrícola en el archipiélago (forrajeras,
hortícolas, frutales tropicales, etc.), en presencia o no de patógenos de raíz.
Abstract: Microbial activity in the rhizosphere is greatly responsible for the good functioning of the ecosystem and for the fertility of agricultural soil. Amongst the micro-organisms that are beneficial to the soil, arbuscular mycorrhizal fungi (AMF) such as the plant growth promoting rhizobacteria (PGPR), key constituents of the rhizosphere zone, contribute to improved growth and feeding of the plant, in addition to increased plant tolerance to biotic or abiotic stress. Introducing these micro- organisms to systems guarantees sustainability by helping to optimise soil quality and health, to reduce the release of nutrients and increase yield. This chapter summarises advances in the handling of these rhizospheric micro-organisms in Canary agricultural systems and some of the effects of their being applied, in the first stages of plant growth, to various species of agricultural interest in the archipelago (fodder crops, horticultural crops, tropical fruits, etc.), with or without the presence of root pathogens.
