Increased Induction of Adventitious Rooting by Slow Release Auxins and Elicitors

摘要: Indolebutyric acid (IBA) is the auxin that commonly used for induction of adventitious roots. Our experiments show IBA not active itself but exerts its action by conversion (β-oxidation) into indoleacetic (IAA). This implies a naturally occurring slow release source IAA. We mimicked this principle synthesizing sources, and so decreasing rate metabolic inacti- vation after uptake in plant tissue. The synthetic sources proved to be more effective than standard auxins root induction. Also, method was developed increase action: breakdown products cell structures are known involved plants defense processes (elicitors) enhance tissue sensitivity auxin. combined application elicitors resulted high rooting percentages on very recalcitrant woody plants.
