Abstract
Seed priming have been used successfully in an attempt to improve germination and seedling establishment of many vegetables and field crops. In this study, seeds of corn after disinfected with 0.5% sodium hypochlorite solution were primed with polyethylene glycol (PEG 8000), KNO3 and KH2PO4. The osmotic potential in all solutions were -0.5, -1.0 -1.5 and -2 MPa. Seeds were primed for 24 h at 25±2 C. Measured parameters were Germination Rate (GR), time reach to 50% germination (T50), root and shoot length, seedling fresh and dry weight. Analized of data showd germinatin and seedling growth significantly (p<0.01) affacted by osmopriming treatments.We obtained osmopriming by polyethylene glycol in -0.5 MPa osmotic potential improved germination and seedling growth compared with other treatments.
