Abstract
Current study was conducted to investigate the efficiency of magnetic field (MF) to protect wheat grains during storage period from insect infestation furthermore, studying its influence on seeds viability and seeds components after 6 months storage period. According to observed results, exposure twice at the beginning and middle of storage period (2^nd group) to MF for 36&48 h was the most effective in protecting stored wheat grains from insect infestation for 6 months comparing with other tested exposure periods and untreated seeds while exposure once at the beginning of storage period (1^st group) for 36&48 h was able to protect wheat for 15&19 weeks. Exposure for MF for 6&12 h wasn’t effective comparing with untreated seeds while exposure for 24h was able to protect wheat for only 11 weeks. Magnetic field negatively affected the percent of seeds germination. Using of magnetic water improves germination % of magnetic wheat grains comparing with tap water with all exposure periods. Magnetic field has positive effect on seeds viability in both 1^st & 2^nd tested groups as it increases seedling length and improve seedling vigor index. Exposure for MF for 36&48 h in both groups increased total carbohydrate, crude protein, total fats & crude fiber % which are important for seed germination while it highly decreased ash percentages. The moisture content % was slightly increased but still under limited which useful for safe storage.
