Corn Responsiveness to : Accessing the Effect of Root Exudates on the Bacterial Growth and Its Ability to Fix Nitrogen.

Corn has shown different degrees of positive response to inoculation with the nitrogen- fixing bacteria of the genera . Part of it has been attributed to the plant genotypic variation, including the root exudates, that are used by the bacteria as energy source. In this study, we grew two corn hybrids that differ for their response to , to investigate the effect of different exudates profiles on the bacteria growth and nitrogenase activity.
