Resumo: White oats are cereals that are grown in different regions of the globe because they have good adaptability and final destination. Thus, their cultivation has shown significant increases in order to meet demand, especially for forage production, grains, and animal and human consumption. High-quality seeds are necessary for crop cultivation and white oats are sown in winter when thermal fluctuations may occur. Therefore, the objective of this study was to evaluate the physiological changes in oat seeds exposed to different temperatures during the germination phase. The experiment was a completely randomized design with four replications in a 6 × 4 factorial design. Six cultivars were evaluated: Aphrodite, Altiva, Artemis, Brava, Corona, and Guará at temperatures of 15, 20, 25, and 30 °C, and the following measurements were taken: first germination count, germination, germination speed index (IVG), and seedling length and mass. The results were analyzed using analysis of variance (F test) and the means were compared using Tukey’s test. The cultivars were physiologically affected at the minimum and maximum temperatures. At 15 °C, normal seedlings did not form, whereas the highest germination values were recorded at 20 and 25 ºC, which showed that these temperatures were the most favorable temperatures for the germination process. Vigor declined at 30 °C and there was a greater number of abnormal seedlings and dead seeds.

O uso de sementes de alta qualidade é necessário para a formação da lavoura. O cultivo acontece no inverno e ocorrem oscilações térmicas durante a implantação da cultura, sendo assim, o objetivo do presente trabalho foi avaliar as alterações fisiológicas em sementes de aveia expostas a diferentes temperaturas durante a fase de germinação. O experimento foi disposto em delineamento inteiramente casualizado, com quatro repetições, em fatorial 6 × 4. Foram avaliadas seis cultivares, Afrodite, Altiva, Artemis, Brava, Corona e Guará nas temperaturas 15, 20, 25 e 30 °C por meio de testes de primeira contagem de germinação, germinação, índice de velocidade de germinação (IVG), comprimento e massa seca de plântulas. Os resultados foram submetidos à análise de variância (teste F) e as médias comparadas pelo teste Tukey. As cultivares foram afetadas fisiologicamente nas temperaturas mínima e máxima. A 15 °C não houve formação de plântulas normais. A 20 e 25 ºC foram obtidos os maiores valores de germinação, mostrando-se, portanto, como temperaturas mais propícias ao processo germinativo. A 30 °C, o vigor foi reduzido, apresentando ainda uma tendência de maior número de plântulas anormais e sementes mortas.UEL2021-04-22info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionO artigo aborda as alterações fisiológicas em sementes de aveia submetidas a germinação em diferentes temperaturas.application/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/4139110.5433/1679-0359.2021v42n3Supl1p1473Semina: Ciências Agrárias; Vol. 42 No. 3Supl1 (2021); 1473-1486Semina: Ciências Agrárias; v. 42 n. 3Supl1 (2021); 1473-14861679-03591676-546Xreponame:Semina.
