초록
The present study has been performed to compare the physiological analysis of monocotmodel plant (rice) in response to ionizing irradiations (cosmic-ray, gamma-ray, and Ion beam). Ionizing radiations were implanted into monocot model plant (rice) seed. After irradiation, theseeds were planted in the plastic pots for a growth period of one month. Thereafter, the morphologicaland physiological characteristics including malondealdehyde (MDA) and chlorophyllcontent, activities of antioxidant enzymes in irradiation samples were investigated. We are confirmedthat the activity level of MDA and chlorophyll content were not changed by ionizing irradiationsamples. However, the free radical contents were increased in all irradiated plants. Andthe activities of SOD, POD, and APX were significantly increased by irradiation compared withnon-irradiation plant.
