Abstract	A pesquisa objetivou investigar a producao de substâncias alelopaticas em extratos de Bamburral ( Hyptis suaveolens (L.) POIT.) na germinacao de pepino ( Cucumis sativus L.) sob diferentes concentracoes e horarios do dia. O experimento foi realizado no Laboratorio de Fisiologia Vegetal da Universidade Estadual Vale do Acarau, Sobral, CE. As coletas das folhas foram organizadas por horario e por dia. Para a pesquisa foram ensaiados 15 Tratamentos (T1: 08h 0%; T2: 08h 50%; T3: 08h 100%; T4: 10h 0%; T5: 10h 50%; T6: 10h 100%; T7: 12h 0%; T8: 12h 50%;T9: 12h 100%; T10: 14h 0%; T11: 14h 50%; T12: 14h 100%; T13: 16h 0%; T14:16h 50%; T15: 16h 100%) repetidos 04 vezes. Os dados obtidos foram transformados (x=1+√X) e submetidos ao software ASSISTAT 7.7. As medias foram comparadas pelo teste de Tukey e o delineamento utilizado foi inteiramente casualizado. Os parâmetros avaliados foram: Percentual de Germinacao, Crescimento de Plântula, Comprimento de Radicula e Pesos das Materias Fresca e Seca. As concentracoes de 50% e 100% parecem exercer atividade alelopatica sobre a germinacao das sementes de Cucumis sativus L. Os horarios de coleta de Hyptis suaveolens (L.) POIT. potencialmente alelopaticos positivo foram 10h e 12h nas concentracoes de 50% e 100%.
