RESUMO:

Cassava (Manihot esculenta Crantz) is a crop of great importance in the world agricultural scenario, due to the use of its roots that stand out as an energy source, being consumed by millions of people. Cassava is frequently planted in sandy soils with low fertility, making eminent the need for it to make beneficial associations with endophytic microorganisms that may contribute to the development of this crop. The objective of this study was to isolate endophytic bacteria associated with cassava roots and investigate their potential for the production of indole acetic acid (IAA) and the solubilization of calcium phosphate. Twenty-one endophytic bacteria from six cassva accessions of the BAG of Embrapa Amazônia Oriental were isolated. The IAA production was evaluated by the colorimetric method (Salkowski Reagent) and for the evaluation of the phosphate solubilization capacity, the bacteria were inoculated in NBRIP solid medium. The results showed that 95% of the isolated endophytic bacteria were able to produce AIA and 33% solubilized calcium phosphate in vitro. Thus, these tests revealed important traits for growth stimulation of cassava plants.
