ABSTRACT: Plant-associated
bacteria that inhabit the rhizosphere may influence the plant growth by their
contribution to the endogenous pool of phytohormones and by the activity of ACC
deaminase to decrease the ethylene concentration. The aim of this study was to
analyse the root length growth by the promoting effect of indole acetic acid
producers phytobacteria with ACC deaminase activity, on inoculated seeds of Lens esculenta as synergistic effect on
root elongation. In this study, although the roots of L. esculenta seedlings do
not show a significant promotion, these phytobacteria could be recommended to
treat plants analyzing their added inoculum to increase plant biomass and
retard the effect of ethylene on cultures supplied with Tryptophan and ACC.
