Resumo: | The objective of this study was to evaluate the effect of seeding treatment to zinc application as regards the nutrition and production of dry matter in maize plants. The experiment was conducted under greenhouse conditions, with completely randomized design, arranged in a 2 x 5 factorial and three replications. The treatments corresponded to two maize cultivars, the BRS 1001 and the PZ 677 and five rates of zinc (0, 25, 50, 100 and 200 g of Zn to 20 kg of seeds) as zinc sulfate. The effect on the outgrowth speed was followed after 28 days of sowing and the dry matter production and the zinc level in the leaves and roots were evaluated. There was accumulation in the level of zinc in the leaves and roots with an increase of the rates. However, a significant increase in the dry matter production was not observed. The plants did not present toxicity symptoms with the rates used. |

O experimento foi conduzido em casa de vegetação, utilizando o delineamento experimental inteiramente casualizado, em esquema fatorial 2 x 5, com três repetições. Os tratamentos foram constituídos de híbridos de milho (BRS 1001 e PZ 677), e cinco doses de zinco (0, 25, 50, 100 e 200 g de Zn por 20 kg de sementes), aplicados na forma de sulfato de zinco. Foi avaliado o efeito dos tratamentos sobre o índice de velocidade de emergência das plântulas e, após 28 dias da semeadura, avaliou-se a produção de massa seca e o teor de zinco na parte aérea e nas raízes. O aumento das doses promoveu elevação do teor de zinco na parte aérea e nas raízes das plântulas de milho, mesmo não existindo aumento significativo na produção da massa seca. Os níveis de zinco utilizados não proporcionaram sintomas de toxicidade nas plântulas.Universidade Estadual de Maringá2008-02-11info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/41010.4025/actasciagron.v29i4.410Acta Scientiarum.
