    Experimento: Germinação e Análise de Sementes de Milho (Zea mays)
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2023-10-20) SILVA, Alex Campelo da; LANZA, Daniela Ap.; ASSIS, Guilherme Jr de; JUNIOR, Paulo Cesar Ap. Leal; SILVA, Pedro H. Souza da; Santos, Vanessa Gomes; BLUMER, Silvia
    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.

    Grandes Culturas & Tecnologia na Produção de Sementes
    (Centro Universitário da Fundação de Ensino Octávio Bastos, 2023-10-20) LOGUINI, José Geraldo; FUNARO, Lucio Bolonha; BATIS, Mauricio A.; ALVARENGA, Nelson A.; SANTOS, Pedro H. P. Lopes dos; GIRALDIN, Rafael R.; DEVECHIO, Fernanda de Fátima da Silva; BLUMER, Silvia; COLL, Bruna do Amaral Brogio
    The PI involves study units related to seed production and technology and large agricultural crops. Conducting an experiment with free-choice cultures, using these materials: Trays of different depths for seedling formation, washed medium sand, substrate with balance in (physical and nutritional) composting. Method: sowing in different depths of white lupine culture. With 4 repetitions per depth, 2 reps. in Mogi Mirim, one in Vargem Grande do Sul and another in Casa Branca, where evaluations were carried out, the The main ones were germination up to 21 DAP and calculation of IVG/IVE.
