[The interaction between corn and Burkholderia (Pseudomonas) cepacia].
Burkholderia (Pseudomonas) cepacia is a plant growth promoting rhizobacteria that could improve maize productivity. In this work we studied some properties of B. cepacia strain 0057 in relation to interaction with maize. Spermosphere effect, chemostatic response, indolic compounds and siderophores production were evaluated. We observed inhibitory effect on bacterial growth by maize seeds and their soluble extracts. Root exudates had positive chemiostatic effect. We founded indolic compounds production (20.1 micrograms/ml) and siderophore presence. We think that this microorganisms could improve maize production.
