The invention relates to a treatment to improve the germination of seeds as well as to the seeds which incorporate said treatment, wherein the treatment consists of applying a coating based on an aqueous solution of an enzyme with phytase activity on the surface of the seeds and subsequent drying of the coating in order to obtain a dry seed. The presence of this enzyme in a coating helps the hydrolyzation of the phytic phosphorous, making it more accessible for the seed and thus improving the germination thereof.
