Effect of Embryo Weight and Seed Priming on Seedling Characteristics of Different Maize Cultvars

Abstract An laboratory experiment was carried out during the year 2020 at Seed Technology Laboratory of Crop Department - College Agricultural Engineering Sciences University Baghdad in order to know effect seed priming and size their embryos different cultivars maize on seedling characteristics. The a completely randomized design with four replicates. first factor included three synthetic (Al-Maha, 3 Al-Fajr) Al-Nahrain hybrid. For second factor, it seeds ASA, CK, GA3, KCL, H 2 O , DW DS, addition dry (without priming). were soaked solutions these substances for 24 hours six characteristics related germination process estimated, which weight after stimulation, embryo, time germination, length radicle shoot, its weight. results showed that significantly superior, as gave highest average weight, lowest time, longest radiclelength (0.336 g, 3.12 days, 15.08 cm 0.215 respectively). treatment ascorbic superior giving embryo reached 0.049 gm, stimulating gibberellin mean coleoptile 10.79 cm. Al-Maha cultivar excelled 0.335 0.050 14.42 0.194 respectively. Whereas, Fajr by 9.37 interaction between study factors significant most studied traits.
