Azospirillum baldaniorum Sp245 Induces Anatomical Changes in Cuttings of Olive (Olea europaea L., cultivar Leccino): Preliminary Results

The purpose of the research was to assess potential effectiveness Azospirillum baldaniorum Sp245 in stimulating induction processes related adventitious root formation. In this short communication, we present preliminary results obtained for first time Leccino olive cultivar (Olea europaea L.). Semi-hardwood cuttings were collected at different sampling times (autumn, winter, and spring) subjected root-inductive treatments with strain (AZO) indole-3-butyric acid (IBA), most employed synthetic auxin used nursery production plants. Moreover, two growing substrates, perlite (an inorganic medium) Elepot® (a blend peat, coconut fiber, perlite) tested. Histological assays carried out identify main cellular changes leading highest rates showing more advanced stages rooting inductive signals observed spring sample. events after AZO comparable those IBA, which mainly associated substrate. positive responses semi-hardwood could provide possibility replacing IBA develop perspectives a context organic systems where alternative compounds, able improve rate cuttings, substitute non-permitted agents. induced significant activities be considered valid agent.
