Resumo: Dormancy in tropical grasses is associated with physiological or physical causes present in freshly harvested seeds. The aim of this study was to evaluate the effect of different concentrations of GA3 in the percentage of germination and suppuration of dormancy of Brachiaria brizantha. Seeds of B. brizantha ‘Marandu’ and ‘MG5’ were immersed in different concentrations of GA3 (0, 25, 50, 75 and 100 mg.L-1) for 2h. After this process, the germination and viability of seed were determinated. The design was completely randomized consisting of 5 treatments with 4 replications for both cultivars. Germination was affected by different concentrations of gibberellins and best results were obtained with the use of 62 and 57 mg.L-1 GA3 for ‘Marandu’ and ‘MG 5’, respectively.

Este trabalho teve o objetivo de avaliar o efeito de diferentes concentrações de giberelina (GA3) na germinação e superação da dormência das sementes de Brachiaria brizantha. As sementes de B. brizantha ‘Marandu’ e ‘MG 5’ foram imersas nas diferentes concentrações (0, 25, 50, 75 e 100 mg.L-1) do regulador de crescimento GA3 por um período de 2 horas. Após esse processo, foram determinadas a germinação e a viabilidade das sementes. O delineamento foi o inteiramente casualizado, constando de 5 tratamentos com 4 repetições, para ambas as cultivares. A germinação foi afetada pelas diferentes concentrações de giberelinas e os melhores resultados foram obtidos com emprego de 62 e 57 mg.L-1 de GA3, para as cultivares Marandu e MG 5, respectivamente.UEL2013-05-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresPesquisaapplication/pdfapplication/mswordhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/874210.5433/1679-0359.2013v34n2p657Semina: Ciências Agrárias; Vol. 34 No. 2 (2013); 657-662Semina: Ciências Agrárias; v. 34 n. 2 (2013); 657-6621679-03591676-546Xreponame:Semina.
