Method for the stimulation of seeds of dicotyledonous plants wherein the seeds are primed in a solution containing nonionic nanoparticles of a metal selected from: silver (Ag) gold (Au) copper (Cu) and platinum (Pt) at a concentration from 0.05 ppm to 50 ppm to obtain 40 60% by weight of water content and then dried at room temperature to obtain 10 40% by weight of water content. The invention also relates to the use of a solution of nonionic nanoparticles of a metal selected from: silver gold copper and platinum to stimulate seeds of dicotyledonous plants.
