| Abstract: | To probe into the influences of low temperature stress on the activities of POD and SOD related to resistance to coldness in Isodon japonica (Burm f) Hara var glaucocalyx (Maxim) Hara seedlings.The changes of activities of POD and SOD were measured under 4℃ for eight days of low temperature stress.Before and after the treatment showed the changes of activities of POD and SOD in seedlings gradually increased with stress intensity.The defensive enzyme system can protect oneself from harm of low temperature. |
