Abstract

Com o objetivo avaliar o condicionamento osmótico em sementes de maxixe (Cucumis anguria L.), em duas cultivares (nordestina e norte), visando melhorar a velocidade e uniformização da germinação, foi conduzido um experimento no delineamento experimental inteiramente casualizado com quatro repetições e três tratamentos (sementes não condicionadas, submetidas ao condicionamento osmótico e ao condicionamento osmótico seguido por secagem), com avaliações feitas em laboratório e em casa de vegetação. Para a cultivar Nordestina, o hidrocondicionamento foi o tratamento que proporcionou maiores efeitos sobre as características de germinação e vigor de sementes de maxixe. Enquanto que a cultivar Norte, o hidrocondicionamento com e sem secagem não influenciaram na germinação e vigor das sementes de maxixe, sendo necessário um aprimoramento da metodologia de condicionamento a essa cultivar.
