Resumo: Adenanthera pavonina L. is a native tree specie from India and with extensive distribution in all Brazilian states, whose seeds have dormancy and present medicinal and economical interest. The objective of this research was to evaluate the effect of different temperatures and pre-germinative treatments on the germinative behavior of newly collected A. pavonina seeds. The seeds were submitted to three settled temperatures: 20, 25 and 30ºC; and to five pre-germinative treatments: coating cutting with pliers, friction in sandpaper, immersion for twenty minutes in  sulfuric acid, immersion in water at 80ºC for 5 minutes and control (without any treatment). The vigor of the seeds was evaluated by the percentage, first count, speed and mean time of germination. The experimental design used was a completely randomized with four replications and the averages were compared by the Tukey test, at 5% probability. The best germinative performance of the seeds was at temperatures of 20 and 25°C and in the pre-germinative treatments of mechanical scarification through the coating cutting with pliers and friction in sandpaper, and chemical scarification with immersion for 20 minutes in sulfuric acid.

O objetivo desta pesquisa foi avaliar o efeito de diferentes temperaturas e tratamentos pré-germinativos sobre o comportamento germinativo das sementes de A. pavonina, recém colhidas. As sementes foram submetidas a três temperaturas fixas: 20, 25 e 30ºC; e a cinco tratamentos pré-germinativos: desponte com alicate, atrito em lixa, imersão em ácido sulfúrico por vinte minutos, imersão em água a 80ºC por 5 minutos e testemunha (sem tratamento). O vigor das sementes foi avaliado pela porcentagem, primeira contagem, velocidade e tempo médio de germinação. Utilizou-se o delineamento inteiramente casualizado, com quatro repetições e as médias foram comparadas pelo teste de Tukey, a 5% de probabilidade. O melhor desempenho germinativo das sementes foi nas temperaturas de 20 e 25°C e nos tratamentos pré-germinativos de escarificação mecânica através do desponte com alicate e atrito em lixa, e escarificação química com imersão em ácido sulfúrico por 20 minutos.UEL2009-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/407610.5433/1679-0359.2009v30n4p815Semina: Ciências Agrárias; Vol. 30 No. 4 (2009); 815-824Semina: Ciências Agrárias; v. 30 n. 4 (2009); 815-8241679-03591676-546Xreponame:Semina.
