Pre-sowing seed treated with Polyethylene Glycol (PEG) helps to enhance the germination behavior of seed. So, a lab experiment was conducted to find out the effect of various Polyethylene Glycol (PEG) concentrations on the germination behavior of wheat. Wheat seeds of BARI Gom 27 and BARI Gom 28 were pre-soaked in 0, 5, 10, 15 and 20% PEG solution and untreated seeds were served as control. Results revealed that seed priming enhanced germination percentage (GP), vigor index (VI) and germination index (GI) of wheat seed. The highest GP (95.55%), VI (201.00) and GI (43.73) were obtained from seeds of BARI Gom 27 pre-treated with 10% PEG solution compared to BARI Gom 28 (75.55%, 128.71 and 27.12 of GP, VI and GI, respectively) and then decreased gradually with increasing PEG concentration. Therefore, seed priming helps to enhance the germination behavior of wheat seed.
