Resumo: | The aim of this study was to evaluate the effect of seeds osmotic conditioning in seedlings emergence and plants performance of sunflower. Three lots of seeds sunflower (Catissol), was submited to osmotic conditioning with polyethylene glycol solution, –2,0 MPa in aerated system, under 15 ºC for 8 hour and then was evaluated for germination tests and vigour. Under filed conditions was conducted emergency evaluations of seedling, plants development as well as the productivity and seeds quality, and the accumulation of nutrients in the seeds. The osmotic conditioning improve the survival of seedling, the dry matter mass to aerial part of plants from 60 days after sowing and oil content, in lots with low seeds physiological quality. The osmotic conditioning not increase the seeds yield but promotes the vigour of seeds produced, regardless of the lot used for sowing seeds. |

O objetivo deste trabalho foi avaliar o efeito do condicionamento osmótico de sementes na emergência de plântulas e no desempenho de plantas de girassol. Sementes de três lotes de girassol da cultivar Catissol foram submetidas ao condicionamento osmótico com solução de polietilenoglicol a –2,0 MPa em sistema aerado, sob 15 °C por 8 horas e, posteriormente avaliadas pelos testes de germinação e de vigor. Em condições de campo, realizaram-se as avaliações de emergência de plântulas, de desenvolvimento das plantas, de produtividade e qualidade das sementes produzidas, bem como o acúmulo de macronutrientes nas sementes produzidas. O condicionamento osmótico favorece a sobrevivência das plantas, o acúmulo de massa de matéria seca da parte aérea de plantas a partir de 60 dias após a semeadura e o teor de óleo, em plantas provenientes de lotes de sementes de qualidade inferior. O condicionamento osmótico não aumenta a produtividade de sementes, mas favorece o vigor das sementes produzidas, independente da qualidade de sementes do lote utilizado na semeadura.
