To study the effect of phosphine fumigation treatments (two tablet/ton exposure for 24 hours; two tablet/ton for 48 hours; two tablet/ton for 72 hours, four tablet/ton for 24 hours; four tablet/ton for 48 hours; four tablet/ton for 72 hours; six tablet/ton for 24 hours; six tablet/ton for 48 hours and six tablet/ton for 72 hours ) on the vitality of bread wheat grains cv. Giza 171 at different storage periods (without storage, 3, 6, and 9 months) a factorial experiment was layout using a complete randomized design with three replications at the laboratory of Prof. Dr. Youssef Mohamed Omar, Plant Protection Department, on the middle fifth floor of the educational building of the Faculty of Agriculture, Assiut University during the period from 26 May 2022 to 3 March 2023. Wheat grain, Giza 171, was obtained from the Agronomy Department Farm, Faculty of Agriculture, Assiut University. Glass jars were used and sealed with metal clips with a capacity of 1.5 kg. Tablets of aluminum phosphide were crushed in a crucible in isolation from moisture. Weights were prepared for each jar and placed in cotton, then the jars were closed until the end of the exposure period, and then opened for ventilation for 24 hours, then re-sealed and measurements began. The obtained result showed that the tested storage periods had a highly significant effect on all studied traits. Thus, the maximum mean values of germination
