Resumen

In the present study, attempts were made to analyze the effect of co-inoculation with an efficient phosphate solubilising native isolate Pantoea sp J49 and the symbiotic nitrogen fixing Bradyrhizobium sp SEMIA 6144 strain on Arachis hypogaea L. plants growth. Single and coinoculation of peanut plants growing in plastic pots containing soil with low P content were developed. Plants were harvested at R1 and R4 growth stages and were analyzed in different growth parameters. Survival of strain Pantoea sp J49 was analyzed in soil samples and in root tissues. Plants inoculated only with Pantoea sp J49 showed the highest shoot and root weight in both reproductive growth stages evaluated. Plants co-inoculated with this strain and Bradyrhizobium sp SEMIA 6144 showed increase in aerial dry weight at R1 stage. Survival assays demonstrated that Pantoea sp J49 survives not only in the peanut rhizosphere but also inside plant tissues, including nodules formed when it was co-inoculated with Bradyrhizobium sp SEMIA 6144. Results obtained in this study confirm the great potential of the native Pantoea sp J49 isolate in the promotion of peanut plant growth, probably related with its capacity to solubilise phosphate.
