Abstract:
Method for increasing and/or prolonging in vivo or in vitro activity of plant growth regulators (PGRs), comprising:a) increasing the sensitivity of the plant and/or plant part(s) to the activity of plant growth regulators by administration or application of one or more means which result in a defensive response in the plant; andb) along with or after the administration or application of the one or more means which result in a defensive response in the plants, locally increasing the concentration of active plant growth regulators in a plant and/or plant part(s) by either or both of the following:i) administering the PGR(s) in encapsulated form; orii) administering PGR(s) that have been chemically modified by linking it (them) to one or more carrier molecules, optionally with interposing of a spacer molecule.
