Two laboratory experiments were conducted at Agronomy Department, Faculty of Agriculture, Mansoura University, Egypt, during May 2014 to enhance germination parameters of grain maize hybrid TWC 352 of both old and new harvested grains by soaking in different times in some natural and artificial substances. Every grain types experiment was carried out in factorial experiment in completely randomized design (CRD). The results revealed that new harvested maize grains significantly exceeded old harvested maize grains in most germination parameters. Soaking maize grains in ascorbic acid (AA) at the rate of 100 ppm significantly increased germination parameters. Highest germination parameters were produced from soaking maize grains in different substances for 18 hours. In order that maximize germination parameters of both old or new harvested grains maize hybrid TWC 352, it could be recommended that soaking grains in antioxidant substances such as ascorbic acid or citric acid or salicylic acid or natural substances such as yeast extract at the rate of 100 ppm of each one for 18 hours.
