The Use of Native Arbuscular Mycorrhizal Fungi from Orchards for the Production of Seedlings

The inoculation of endomychorrhyzal fungi in substrates and disinfected soils in nurseries, dues to their ability to improve the radicular system, may increase biotic and abiotic stresses and leading to the production of high-quality plants in systems that use lower amounts of agricultural inputs (Souza et al., 2002). Another factor that affects the production of inoculum in large quantities is the fact that it is not clear which species is actually colonizing the roots. [...]expectations regarding the use of selected AMF inoculum cannot be made yet, as the knowledge about the colonization strategies and their functioning under field conditions is still insufficient. [...]soil management conditions may determine changes in the profile of predominant species able to colonize the plants present in the area. [...]the importance of identify the species present in a determined region, where certain cultural practices are adopted, aim at the use of these species in the production of seedlings for use in the same region.
