In order to verify the interference of the excision of corn seed parts on their biological performance, this research was carried out by removing nearly 0, 14, 28 and 37% in weight from the seed, without influencing the embryo. The evaluation which was carried out in laboratory (germination and vigor) and in the field (outgrowth and yield) allowed the following conclusions: - There is a biological possibility of excising corn seed parts (±14% in weight), in pre-sowing and with fungicidal treatment, in high physiological quality lots to be sowed in suitable areas for the species upgrowth; the remotion of corn seed parts leads to the reduction of its conservation potential.
