Radiations have always been environmentally important. Natural radioactive resources in soil, water, weather, and manmade resources from mining, and applying their products in industrial and army fields have resulted in exposure to ionizing radiations. Nowadays, radiological effects on plants and animals are of a critical concern. Among the remarkable radiological issues in in different species of plants is the wide range of their sensitivity to ionizing radiations. The most important radiation damages in plants can be divided into three modes, including growth inhibition, reduction in reproduction capacity, and death. The purpose of the present research is to study the effect of Gamma Ray on seedling growth and on morphological and phenotypic properties of corn seedlings. The corn seeds (single cross 704) are radiated by Gamma Ray of 0.026 and 0.06 Mev for 24, 48, and 72 hours. The results show that radiation significantly influenced such growth features as the plant height, root length, plant weight, root weight, stem diameter, the number of ears, leaf width, ear weight, the number of seed, and the seed weight of corn. The largest amounts of the mentioned features are obtained from one-day radiation and the increase in radiation up to three days causes significant reduction in all features.
