Abstract	O presente trabalho teve como objetivo verificar a influencia do condicionamento fisiologico sobre a germinacao e a emergencia de sementes de pepino. Os ensaios foram conduzidos no Laboratorio de Analise de Sementes e na Horta Didatica do Departamento de Ciencias Vegetais da Universidade Federal Rural do Semi-Arido – UFERSA, no periodo de setembro a outubro de 2009. Para isso, utilizaram-se sementes de pepino, cultivar Aodai que foram hidrocondicionadas em papel-toalha, a 20 oC ate atingir 43% de agua. Posteriormente, foram secadas em temperatura ambiente (27-30 oC e 45-55% de umidade relativa, ate atingirem 7,3% de agua. As sementes foram avaliadas pelos testes de germinacao, indice de velocidade de germinacao, primeira contagem de germinacao, indice de velocidade de emergencia, emergencia em casa de vegetacao, altura da parte aerea da plântula e massa da materia seca da parte aerea. O hidrocondicionamento pode favorecer a velocidade de germinacao e de emergencia de plântulas, mas esses efeitos nao sao suficientes para persistir durante o desenvolvimento final das plântulas.
