Abstract
O presente trabalho objetivou estudar. os efeitos de diferentes
métodos de escarificação do tegumento na quebra da dormência de sementes de Brachiaria decumbens, As sementes foram submetidas a escarificações química,mecânica e térmica durante diferentes períodos de tempo. Concluiu-se que os três métodos empregados foram capazes de quebrar a dormência das sementes desta espécie, entretanto o método
mecânico foi mais eficiente.
