中文摘要：
[目的]研究重金属Cd胁迫对不同玉米品种生理生化指标的影响,为重金属生态毒理学研究提供理论依据。[方法]以辽宁地区大面积种植的玉米品种铁南2号,营丹11号和郑丹958号为供试材料,探讨了不同浓度Cd2＋胁迫对玉米种子萌发及幼苗生理生化指标的影响。[结果]低浓度Cd胁迫表现为一定的刺激作用,较高浓度某种程度上则表现了明显的抑制性。当Cd2＋浓度大于5mg/L时,对不同玉米种子萌发均有明显的抑制效应,并且随着Cd2＋浓度的增加,对Cd耐受程度不同的玉米品种其幼苗生长及其外渗电导率、叶绿素含量等生理生化指标产生明显差异。[结论]铁南2号玉米品种对重金属Cd的抗性明显比其他2种玉米品种强。
英文摘要：
[Objective] This paper aimed to investigate the effects of cadmium（Cd）stress on physiological and biochemical indexes in different maize cultivars and provide theoretical basis for the study on heavy metal ecotoxicology.[Method] The maize cultivars includeing Tienan 2,Yingdan 11 and Zhengdan 958 which were widely planted in Liaoning Province were selected as the experimental materials.And then the effects of different Cd2＋ concentrations on seed germination,physiological and biochemical indexes of young seedlings were investigated.[Result] The lower Cd2＋ concentration showed some the stimulation effect on seed germination of maize,while the higher concentration had obvious inhibitory effect to some extend.The seed germination of all the maize verities was obviously inhibited when the Cd2＋ concentration was more than 5 mg/L.And with the increasing of the Cd2＋ concentration,the seedling growth,exosmic conductivity and chlorophyll content of the maize varieties with different tolerance to Cd2＋ were distinctly changed.[Conclusion] The resistance of Tienan 2 to Cd2＋ was significantly higher than that of the other two varieties.
