镉锌处理麦苗对中华稻蝗(Oxya chinensis)体内锌、镉水平及生化指标的影响
Effects of Cadmium and Zinc in Wheat Seedlings on Heavy Metal Accumulation and Biochemical Indices of Oxya chinensis
摘要
Abstract
In order to study the interaction effects of cadimun(Cd) and zinc(Zn),Oxya chinensis were fed with the wheat seedlings cultured in solutions with different concentrations of Cd2+ and Zn2+.Accumulation of Cd and Zn in the wheat seedlings and the grasshoppers were measured.The content of malondialdehyde (MDA),superoxide dismutase (SOD) activity,glutathione peroxidase(GPx) activity and total antioxidant capacity(T-Aoc) in the grasshoppers were analyzed.The results showed that Zn contents increased significantly in the seedlings and grasshoppers when Zn concentration was increased and the Cd concentration was constant in solutions.When treated with the mixture of 20 mg· L-1 Cd2+ and 200 mg· L-1 Zn2+,Zn contents in the seedlings and grasshoppers were 2.03 and 1.63 times higher than that in the control,respectively.Cd contents showed a tendency of first increase and then decline,and reached the highest when treated with mixture of 20 mg·L-1 Cd2+ and 100 mg· L-1 Zn2+.The contents of MDA increased in the grasshoppers with Zn concentration increasing under the interaction of Zn and Cd.SOD activity firstly increased then declined.Compared with the control,GPx activity increased when treated with 20 mg· L-1 Cd2+ alone and decreased when treated with the mixture of Cd and Zn.T-Aoc content reached the highest under the treatment of 20 mg· L-1 Cd2+ and 100 mg· L-1 Zn2+.These results indicated that low concentrations of Zn could increase the accumulation of Cd in O.chinensis.The interaction of Zn and Cd could cause the damage of lipid peroxidation.关键词
