英文摘要: The effects of cerium (Ce) on protecting Jerusalem artichoke (Helianthus tuberosus L.) against oxidative stress induced by salinity were studied. Exposure to NaCl (150 mM) markedly inhibited the growth of H. tuberosus seedlings and the inhibition was significantly alleviated by CeCl3 (0.1 mM). The result showed that CeCl3 prevented decline in the chlorophyll content induced by salinity. The contents of hydrogen peroxide ((HO2)-O-2), superoxide radicals (O-2 center dot(-)) and malondialdehyde (MDA) were increased, which suggested that oxidative stress induced by salinity. Addition with CeCl3 dramatically depressed H2O2, O-2 center dot(-) and MDA accumulation caused by salt stress. Furthermore, the activities of superoxide dismutase (SOD), catalase (CAT) and peroxidase (POD) in H tuberosus seedlings under salt stress were also increased. The data suggested that appropriate concentration CeCl3 could protect H tuberosus from salinity-induced oxidative stress by reducing cellular level of ROS directly and by improving antioxidant defense system.
