Resumo: Seed dormancy limits the seedling production and potential of use in Adenanthera pavonina L. The objective of this research was to evaluate the best dormancy breaking method in Adenanthera pavonina L. seeds. It was carried out at the Ceulji/Ulbra Laboratory of Botany, from April to June 2007, and six dormancy breaking treatments (T) were tested: T1 - Boil for 15 minutes and rest for 16 hours, in the same water; T2 - Boil for 10 minutes and rest for 16 hours, in the same water; T3 - Immersion in boiling water (95ºC) and rest for 24 hours, in the same water; T4 and T5 - Immersion in concentrated sulfuric acid (98%), for 5 and 10 minutes, respectively; and T6 - Control. The following items were evaluated: days until germination, germination speed index (GSI), and germination percentage (%GER). Variance analysis was used to evaluate the data and means were compared by using the Duncan’s test (5%). Treatments 1 and 2 caused seeds damage, preventing their germination. Treatments 4 and 5 showed no significant differences, but were more favorable to dormancy breaking, if compared to the other treatments. KEY-WORDS: Germination; chemical scarification; boiling; sulfuric acid.

O presente trabalho objetivou determinar o melhor método para quebra de dormência, em sementes de A. pavonina. O experimento foi conduzido no Centro Universitário Luterano de Ji-Paraná (Ceulji/Ulbra), de abril a junho de 2007. Foram testados seis tratamentos (T): T1 - Fervura por 15 minutos e repouso por 16 horas, na mesma água; T2 - Fervura por 10 minutos e repouso por 16 horas, na mesma água; T3 - Imersão em água quente (95ºC) e repouso por 24 horas, na mesma água; T4 e T5 - Ácido sulfúrico concentrado (98%), durante 5 e 10 minutos, respectivamente; e T6 - Testemunha. Avaliou-se o índice de velocidade de germinação (IVG), percentagem de germinação (%G) e massa de matéria seca de plântulas. Os dados foram submetidos a análise de variância, sendo as médias comparadas pelo teste de Duncan, a 5% de significância. Sementes submetidas a fervura, por 10 e 5 minutos, foram deterioradas, o que impediu a germinação. A imersão das sementes em ácido sulfúrico, por 5 e 10 minutos, foi mais favorável à superação da dormência, em relação aos demais tratamentos.
