초록

We investigated the physiological responses by acute and chronic gamma-irradiation in rice. The rice, Oryza sativa L. cv Dongan, plants were irradiated with 100 and 400 Gy of gamma-rays for acute and chronic irradiation, and their morphological, chlorophyll content, MDA, proline and activities of antioxidant enzymes were examined. The plant height of chronic irradiation samples were decrease with increase of a does than the control, but the number of tiller and dry weight of shoot were increased 100 Gy. Carotenoid and chrolorphyll content were decreased of all irradiated plants than non-irradiated plants. But, MDA and proline content were increased in 400 Gy both acute and chronic gamma irradiation. And the activities of antioxidant enzymes were different as gamma-irradiation patterns.
