Method of treating plants or plant tissues

Abstract From the Canadian patent

A method is provided for treating plants or plant tissues (including cuttings roots, bulbs, corns, tubers, rhizomes and seeds) in order to induce a desired tissue morphology and/or a desired physiological state by applying to the plant an amount of a C-16,17-dihydro gibberellin or C-16,17-dihydro gibberellin precursor effective to produce an at least partial inhibition of the formation of effector gibberellins in said plant. Effects obtainable include dwarling, stem and shoot and/or root (radicle) growth retardation, flowering, improved fruit quality inhibiting fruit ripening, improving fruit set controlling weed growth, inducing, male sterility retarded bud break and tillering.
