| Abstract | ||
| This investigation was conducted under the laboratory conditions of Seed Technology Research Unit, Mansoura and field conditions of the Experimental Farm, Tag El Eizz Research Station Dakahlia Governorate, (ARC) during 2015 year. The objectives of the experiment were to evaluate the effect of some pre-sowing seed treatments on seed germination, seed and seedling vigor traits and field emergence of teosinte seed (Zea Mexicana). Seed treatments were dry heat (70°C and 80°C) for 3, 5 and 8 minutes; hot water for 5 and 10 minutes; H2SO4 75% for 15 and 20 minutes; cold storage (4°C) for 1, 2 and 3 months; static magnetic field 60 mT for 0, 6 and 12 hours; dry seeds and wet seeds. The main reveled that, treating teosinte seed pre-sowing by dry heat (70°C for 5 minutes or 80°C for 3 minutes) improved seed quality treats i.e. germination percentage, seed and seedling vigor traits. Expose teosinte seed to static magnetic field (60 mT for 6 hours produced the fastest mean germination time. Soaking teosinte seed in H2SO4 75% for 15 minutes) produced the fastest germination speed and highest field emergence%. General, we can get high germination percentage, seed and seedling vigor under laboratory and field emergence consequently high plant density under field condition by treating teosinte seed (c.v. population Damietta) with dry heat or H2SO4 75% for 15 minutes. | ||
