Abstract: Methods for reducing leaf senescence in plants or portions of plants by treating them with methyl dihydrojasmonate are disclosed. The methyl dihydrojasmonate may be in the form of an aqueous foliar spray, which may also include additives such as wetting agents, adjuvants, emulsifiers, dispersants, spreaders, surfactants, anchorage, disintegrants, and plant nutrients.

Abstract: Methods of seed treatment with one or more jasmonates are described. One method comprises exposing a seed to a formulation containing methyl dihydrojasmonate (MDHJ) at an amount and duration effective for improving a germination characteristic of the seed. Another method comprises exposing a seed to a formulation containing MDHJ at an amount and duration effective for improving a stress tolerance characteristic of the seed. Seeds comprising an effective amount of MDHJ for improving a germination or stress tolerance characteristic are also described.

Abstract: Compositions and methods for improving a plant's resistance to biotic and/or abiotic stress are provided, including methods of seed production comprising: (a) providing a plant or part thereof; (b) exposing the plant to a composition comprising one or more defense activators present in a concentration ranging from 0.01 mg/l to 25 g/l or from 0.25 nM to 10 mM and chosen from jasmonates, salicylic acid, chitin, acibenzolar-S-methyl, harpins, microbes, and one or more defense peptides comprising a consensus amino acid sequence: wherein: X is an amino acid chosen from Alanine (A), Cysteine (C), Aspartic acid (D), Glutamic acid (E), Phenylalanine (F), Glycine (G), Histidine (H), Isoleucine (I), Lysine (K), Leucine (L), Methionine (M), Asparagine (N), Proline (P), Glutamine (Q), Arginine (R), Serine (S), Threonine (T), Valine (V), Tryptophan (W), or Tyrosine (Y); (c) growing the plant to produce developed seeds from the plant comprising defenses induced by the defense activators.

Abstract: Methods for reducing leaf senescence in plants or portions thereof by treating them with a solid preparation of methyl dihydrojasmonate are disclosed, as are appropriate solid preparations of methyl dihydrojasmonate. The solid preparations may be applied, for example, to the roots or to the growth medium of the plants.

Abstract: Methods for reducing leaf senescence in plants or plant portions by treating them with methyl dihydrojasmonate are disclosed. The methyl dihydrojasmonate may be in the form of an aqueous foliar spray, which may also include additives such as wetting agents, adjuvants, emulsifiers, dispersants, spreaders, surfactants, anchorage, disintegrants, and plant nutrients.

Abstract: Methods and formulations for improving the flowering characteristics of plants, such as rose plants, are disclosed. The formulations include methyl dihydrojasmonate: Methods and formulations according to embodiments of the invention may increase the duration that cut flowers last, increase the degree to which buds open to full flower, and increase the turgidity of stems. They may also prolong flower opening on intact flowering plants.

Abstract: Formulations and methods for treating and preventing biotic attack, including disease and insect infestation, in plants are disclosed. The formulations include methyl dihydrojasmonate: Formulations according to embodiments of the invention are particularly suitable for controlling insect infestation and disease in roses.
