Experimento: Germinação e Análise de Sementes de Milho (Zea mays)

Abstract

Brazil has advanced in seed technology research and especially in commodities such as corn (Zea mays) given the great nutritional and commercial importance of the crop. So many researches are aimed at germination tests in the Rules for Seed Analysis (BRASIL, 2009). A Seed germination is influenced by environmental factors such as: temperature, type of substrate, seed quality and adequate nutritional conditions for effective germination. Technically, these factors influence the percentage, speed and uniformity of germination, resulting in seedlings more vigorous, as well as reduced production costs. In corn, rapid germination and emergence uniformity are fundamental characteristics to allow high productivity. The depth of Sowing is the factor that most influences the emergence and development of this crop. The project Integrated proposed in the Major Crops module brings the challenge of cultivating and analyzing the seeds of corn at different depths to evaluate seed vigor and the implications of seed depth. seeding in the final crop stand over time. Thus, studies by Yorinori (1996) on the emergence of corn served as inspiration to pursue the proposition that depth impacts the germination process. Therefore, the objective of this research was to verify the implications of the depth sowing method used by rural producers, correlating with information on the physiology of germination and growth of seedlings.
