The invention herein relates to a procedure to assist in the germination, growth and development of seeds or plants, from a support of plant origin especially from macrophyte plants.A fundamental part of the procedure involves a support of plant origin which consists of a longitudinal segment of the leaf of a macrophyte plant that has been dried, the result being the appearance of a macaroon, having an outer plant coating and an inner circular portion filled with a porous tissue. This procedure described herein involves the use of the support of plant origin described above for the germination of seeds contributing to the growth and feeding of the seed until it becomes a plant, using the segment of macrophyte, said segment having particular characteristics as provider of oxygen and nutrition.
