Resumo: Optimization of seed density range, combined with the use of quality seeds may help generate more profit from wheat production, as these factors affect grain yield and the quality of seeds. The aim of this study was to evaluate the effects of initial vigor level and sowing densities on the productive performance of the plants and the physiological performance of the seeds of two wheat cultivars in two cultivation environments. The experiment was carried out in the cities of Londrina and Ponta Grossa, Paraná, Brazil, in a randomized block design with four replications, following a 2 × 2 × 4 factorial scheme with two levels of seed vigor (high and low), two cultivars (BRS Gralha-Azul and BRS Sabiá), and four sowing densities (150, 250, 350, and 450 seeds m - 2). The following characteristics were evaluated: emerged seedlings, shoot dry matter, spike density, vegetation index, and grain yield. Additionally, the physiological potential of the seeds produced in Londrina was evaluated by first germination count, germination, accelerated aging, seedling emergence, and emergence speed index tests. The increase in density up to 450 seeds m-2 favored the productive performance of the crop in both cultivation environments; however, it reduced the physiological performance of the seeds produced in Londrina. Both cultivars had better performance and grain yield in Londrina and Ponta Grossa, respectively. High-vigor seeds favored the establishment of the stand, especially under unfavorable environmental conditions.

O objetivo do trabalho foi avaliar os efeitos do nível de vigor inicial e das densidades de semeadura sobre o desempenho produtivo das plantas e o desempenho fisiológico das sementes de duas cultivares de trigo em dois ambientes de cultivo. O experimento foi conduzido nas cidades de Londrina e em Ponta Grossa, Paraná, Brasil, em delineamento experimental de blocos casualizados com quatro repetições, em esquema fatorial 2 × 2 × 4, sendo avaliados dois níveis de vigor de sementes (alto e baixo), duas cultivares (BRS Gralha-Azul e BRS Sabiá) e quatro densidades de semeadura (150, 250, 350 e 450 sementes m -2). As seguintes características foram avaliadas: número de plântulas emergidas, matéria seca da parte aérea de plantas, densidade de espigas, índice de vegetação e rendimento de grãos. Adicionalmente, foi avaliado o potencial fisiológico das sementes produzidas em Londrina pelos testes de primeira contagem, germinação, envelhecimento acelerado, emergência de plântulas e índice de velocidade de emergência. O aumento da densidade até 450 sementes m -2 favoreceu o desempenho produtivo da cultura nos dois locais de cultivo, porém, reduziu o desempenho fisiológico das sementes produzidas em Londrina. As cultivares BRS Gralha-Azul e BRS Sabiá apresentaram desempenho e rendimento de grãos superiores em Londrina e Ponta Grossa, respectivamente. Sementes de alto vigor favorecem o estabelecimento do estande, principalmente em condições ambientais desfavoráveis.UEL2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa de CampoPesquisa de Campoapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4213410.5433/1679-0359.2021v42n3Supl1p1595Semina: Ciências Agrárias; Vol. 42 No. 3Supl1 (2021); 1595-1614Semina: Ciências Agrárias; v. 42 n. 3Supl1 (2021); 1595-16141679-03591676-546Xreponame:Semina.
