Foi investigado o potencial alelopatico das flores de Acacia podalyriaefolia A. Cunn.. O estudo da atividade alelopatica demonstrou que o extrato etanolico bruto e suas fracoes diclorometano e acetato de etila tem influencia significativa sobre a germinacao e crescimento das radiculas e hipocotilos de Lactuca sativa. O efeito verificado foi de ativacao da germinacao das sementes, porem sem o desenvolvimento dos foliolos tornando as mudinhas inviaveis. ALLELOPATHIC EFFECTS FROM FLOWERS of Acacia podalyriaefolia A. CUNN. Abstract The allelopathic potential from the flowers of Acacia podalyriaefolia A. Cunn. was investigated. The study of the allelopathic activity have demonstrated that the crude ethanolic extract and its fractions dichloromethane and ethyl acetate have significant influence in the germination and in the growth of radicle and of the hypocotyls from the Lactuca sativa. The effect was the activation of the germination of the seeds, although the developing of the follicles was prejudiced turning the saplings unviable.
