Effect of Osmopriming with Polyethylene Glycol (8000) on Germination and Seedling Growth of Wheat (Triticum aestivum L.) Seeds under Salt Stress

摘要

Due to increased salinity problems, efforts are being made to develop strategies to ameliorate salt stress. This study was conducted to evaluate the effectiveness of osmopriming in ameliorating salinity stress effects in wheat (Triticum aestivum L.). Seeds were primed for 12 h with solutions of polyethylene glycol (PEG 8000). The osmotic potentials of the PEG solutions were-0.4, -0.8 and -1.2 MPa. The control was not treated with (PEG). The experiment was factorial based on CRD with three replications. Salinity levels were 4, 8, 12 and 16 dS m 1. Results showed osmopriming by polyethylene glycol 8000 can be improved germination and seedling compared to control (non-priming) under salt stress condition.
