Improving the Adventitious Rooting Ability of Hard-to-Root Olive (Olea europaea L.) Cultivar Cuttings Through Inhibiting Strigolactone Biosynthesis

Strigolactones (SLs) are synthesized in roots and control plant development. As phytohormones, SLs regulate architecture, including roots. Recently, the inhibiting effects of on adventitious rooting have been identified. Olive (Olea europaea L.) is consumed for oil table Mediterranean countries an economically important crop. Turkey one with highest olive production. has mostly propagated asexually via cuttings, however, capacities some agriculturally cultivars very low. Indole Butyric Acid (IBA) commonly used to promote it can be inadequate. Ayvalık easy-to-root cultivar most common grown production Domat a hard-to-root which IBA insufficient inducing rooting. In our study, synthetic rac-GR24 biosynthesis inhibitor TIS108 ability cuttings were investigated. result, was increased when treated TIS108, indicating promising future olive-cutting Therefore, study will provide potentially new tools propagation strategies using fruit trees.
