Resumo: In wheat crops, it is often observed that the number of plants per area is lower than that of viable seeds used, which may be related to both environmental conditions and seed vigor. The aim of this study was to assess the effect of seed vigor level at different sowing densities on growth, development, and grain yield in wheat cultivars. The experiments were conducted in Londrina and Ponta Grossa, PR, Brazil, under a randomized block design in a 2 × 2 × 3 factorial scheme, with four replications. Two seed vigor levels (high and low), two sowing densities (200 and 400 viable seeds per m2), and three wheat cultivars (BRS Sabiá, BRS Gaivota, and BRS Gralha Azul) were assessed. In order to assess growth and development, plant samples were collected at the phenological stages of seedling growth, stem elongation, booting, and ear emergence. We assessed the emergence of seedlings, height and dry matter of plant shoot, and grain yield. The sowing density of 200 seeds per m2 led to a higher shoot dry matter production per plant at the stages booting and ear emergence. The cultivar BRS Sabiá presented the highest grain yield in Londrina, while BRS Sabiá and BRS Gralha Azul presented the highest grain yield in Ponta Grossa. High vigor seeds favor stand establishment, growth and development of plants at early phenological stages, and grain yield of wheat.

O objetivo foi avaliar o efeito do nível de vigor de sementes, em diferentes densidades de semeadura, sobre o crescimento, o desenvolvimento e o rendimento de grãos em cultivares de trigo. Os experimentos foram conduzidos em Londrina e Ponta Grossa, PR, Brasil, sob o delineamento experimental de blocos casualizados, em esquema fatorial 2 x 2 x 3, com quatro repetições. Foram avaliados dois níveis de vigor de sementes (alto e baixo), duas densidades de semeadura (200 e 400 sementes viáveis por m2) e três cultivares de trigo (BRS Sabiá, BRS Gaivota e BRS Gralha Azul). Para avaliação do crescimento e desenvolvimento foram realizadas coletas de plantas nos estádios fenológicos de desenvolvimento da plântula, alongamento do colmo, emborrachamento e emergência da inflorescência. As avaliações efetuadas foram: emergência de plântulas, altura e massa seca da parte aérea de plantas e produtividade de grãos. A densidade de semeadura de 200 sementes por m2 acarreta maior produção de massa seca da parte aérea por planta nos estádios de emborrachamento e emergência da inflorescência. Em Londrina, a cultivar BRS Sabiá e, em Ponta Grossa, a BRS Sabiá e a BRS Gralha Azul apresentam maiores produtividades de grãos. Sementes de alto vigor favorecem o estabelecimento do estande, o crescimento e o desenvolvimento das plantas nos estádios fenológicos iniciais e a produtividade de grãos de trigo.Universidade Federal Rural do Semi-Árido2018-10-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufersa.edu.br/caatinga/article/view/749210.1590/1983-21252018v31n411rcREVISTA CAATINGA; Vol. 31 No. 4 (2018); 891-899Revista Caatinga; v. 31 n. 4 (2018); 891-8991983-21250100-316Xreponame:Revista Caatingainstname:Universidade Federal Rural do Semi-Árido (UFERSA)instacron:UFERSAenghttps://periodicos.ufersa.edu.br/caatinga/article/view/7492/9858Copyright (c) 2018 Revista Caatingainfo:eu-repo/semantics/openAccessAbati, JuliaBrzezinski, Cristian RafaelZucareli, ClaudemirFoloni, José Salvador SimonetiHenning, Fernando Augusto2023-07-20T13:52:53Zoai:ojs.periodicos.ufersa.edu.br:article/7492Revistahttps://periodicos.ufersa.edu.br/index.php/caatinga/indexPUBhttps://periodicos.ufersa.edu.br/index.php/caatinga/oaipatricio@ufersa.edu.br|| caatinga@ufersa.edu.br1983-21250100-316Xopendoar:2024-04-29T09:46:35.294238Revista Caatinga - Universidade Federal Rural do Semi-Árido (UFERSA)true
