Physiological Responses of Three Different Plants to Low-Doses of 137Cs-γ Irradiation
Abstract:
Gamma irradiation has been widely applied in biology and medicine in terms of biological effects from low doses stimulation to high-doses inhibition. This study investigates the physiological responses for plantlets of Pepper, Eggplant, and Chinese Cabbage by low-doses of 137Cs-γ irradiation. The results show that the POD activity and the content of MDA and soluble protein increased after gamma irradiation except for Chinese Cabbage. A significant positive correlation was observed between POD and MDA. Soluble Protein and the others had a negative correlation for Chinese Cabbage. Mechanisms of plants under irradiation should have a more profound study in order to determine the correlation.
