  • Method of treating plants or plant tissues with C-16,17-dihydro gibberellins
    Patent number: 5532206
    Abstract: 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 dwarfing, 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.
    Type: Grant

  • Promotion of flowering of fruit trees
    Patent number: 5085683
    Abstract: The flowering of broad-leaved trees particularly fruit trees is promoted by applying a selected rapidly metabolizable gibberellin. Use of the method of the invention can promote return flowering and prevent biennial bearing.
    Type: Grant
    Filed: June 1, 1990
    Date of Patent: February 4, 1992
    Inventors: Richard P. Pharis, Norman E. Looney, Lewis N. Mander
  • Promotion of flowering in fruit trees
    Patent number: 4941908
    Abstract: The flowering of broad-leaved trees, particularly fruit trees, is promoted by applying as a foliar treatment, a selected rapidly metabolisable gibberellin chosen from among gibberllin A.sub.4, C-3 epi-gibberellin A.sub.4, gibberellin A.sub.1, and salts and esters thereof. Use of the method of invention can promote return flowering and prevent biennial bearing.
