Abstract

The characterization of some bacterial genera present in the plant rhizosphere of gerbera (Gerbera jamesonii) and carnation (Dianthus barbatus and Dianthus caryophyllus) was carried out on a Compacted Red Ferralitic soil located in San José de las Lajas. The rhizobacteria studied (Pseudomonas (Burkholderia) cepacia, P. fluorescens and Azospirillum brasilense) showed chemoattraction of root exudates. In both cases, the Spermospheric Model was used. Results demonstrated that Pseudomonas is a dominant population over Azospirillum, Bacillus and Streptomyces. Pseudomonas (Burkholderia) cepacia showed the maximum chemotactic responses to root exudates of gerbera and carnation after 14 days and 40 minutes of exposure.
