Description
Summary:Pre-sowing seed treated with Polyethylene Glycol (PEG) assumed to be a potential priming agent to increase the germination behavior of seed. For this regard, a lab investigation was carried out to find out the suitable pre-sowing priming time on the germination, seedling growth and water relation behavior of four wheat genotypes viz., BARI Gom 28, ESWYT-5, ESWYT -6 and ESWYT-7. The seeds of wheat genotypes were primed with 10% PEG solution for 3 h, 6 h, 9 h, 12 h and 15 h. The results of the experiment revealed that, among 4 wheat genotypes ESWYT-5 wheat genotype performed best in most of the germination, seedling growth and water relation behaviors of wheat under all priming times followed by ESWYT-6 and BARI Gom 28 and ESWYT- 7 showed consistently poor performance. The germination, seedling growth and water relation behaviors’ value of wheat genotypes increased with increasing priming time up to 9 h and then gradually decreased. All the parameters of wheat genotypes gave the best results when seeds treated with 10% PEG solution for 9 h compared to the other priming times and 3 h scored the lowest results. So, it can be concluded that priming time helps to increase the germination, seedling growth and water relation behaviors of wheat genotypes.
