1 . A kit for preparing an imbibition medium in a treatment for priming seeds, comprising and configured for a combined application of (a) and (c), wherein (a) and (c) are:
(a) (1) nitrates, (2) sulfates, (3) phosphates, (4) gibberellins, and (5) sodium nitroprusside, wherein the concentration of each of (a)(1), (a)(2), (a)(3), (a)(4) and (a)(5) in the imbibition medium is 0.001-10 mM, and
(c) proline, ascorbic acid and/or its salts, and reduced glutathione.
2 . The kit according to claim 1 , further comprising:
(b) one or more agents capable of providing protection to said seeds and/or the plants resulting therefrom, the concentration of each of said agents in the imbibition medium being 0.1-10 mM.
3 . The kit according to claim 1 , wherein
the concentration of each of (a)(1), (a)(2), (a)(3), (a)(4) and (a)(5) in the imbibition medium is 0.01-10 mM.
4 . The kit according to claim 1 , further comprising nitrites, ethylene, precursors of ethylene, ammonium salts, or mixtures thereof.
5 . The kit according to claim 1 , wherein (a) is potassium nitrate at a concentration in the imbibition medium of 0.1-10 mM, calcium nitrate at a concentration in the imbibition medium of 0.1-10 mM, magnesium sulfate at a concentration in the imbibition medium of 0.1-10 mM, monobasic potassium phosphate at a concentration in the imbibition medium of 0.1-10 mM, potassium hydrogen phosphate at a concentration in the imbibition medium of 0.1-10 mM, gibberellic acid at a concentration in the imbibition medium of 0.01-1 mM and sodium nitroprusside at a concentration in the imbibition medium of 0.01-1 mM.
6 . The kit according to claim 2 , wherein the agent(s) (b) is/are chosen from the stimulators of the natural defenses of the seeds and the stimulators of the natural defenses of the plants resulting from said seeds, in response to a biotic stress and/or an abiotic stress.
7 . The kit according to claim 6 , wherein the stimulators of the natural defenses of the seeds are chosen from molecules of the salicylate family at a concentration in the imbibition medium of 0.05-3 mM, derivatives of salicylic acid, and acibenzolar-S-methyl.
8 . The kit according to claim 7 , wherein the derivatives of salicylic acid are chosen from sulfosalicylic acid and methyl salicylate, and are in a concentration in the imbibition medium of 0.1-5 mM.
9 . The kit according to claim 1 , wherein the proline is in a concentration in the imbibition medium of 0.1-30 mM.

12 . The kit according to claim 1 , wherein the reduced glutathione is in a concentration in the imbibition medium of 0.01-5 mM.
13 . A method for treatment of seeds comprising the following steps:
imbibing the seeds in an imbibition medium obtained from a kit according to any one of claim 1-3, 4, 5-8, 9-10, or 11-12 , and then
dehydrating the imbibed seeds.
14 . The method according claim 13 , wherein the seeds are imbibed by impregnation or spraying with said imbibition medium.
15 . The method according to claim 13 , wherein the seeds are chosen from seeds of cultivated or cultivable plant species.
16 . The method according to claim 15 , wherein the seeds are chosen from vegetable seeds, aromatic seeds, floral seeds and field seeds.
