镉铅复合胁迫对茭白抗氧化酶活性的影响
Effects of Cd and Pb Combined Stress on the Antioxidant Enzyme of Zizania latifolia
摘要
Abstract
[Objective] The purpose was to seek for the change of antioxidant enzyme of Zizania latifolia, when treated with heavy metal.[Method] Change of the antioxidant enzyme in leaves of Zizania latifolia was studied on single-harvested cultivar Jiangshu and double-harvested cultivar Fenghongzao which cultured in soil with 100 mg/L Cd2+, 1 000 mg/L Pb2+ and their combined stress.[Result] When treated with single stress and combined stress of Cd and Pb, the antioxidant enzyme in leaves was reduced.The reduced range order was combined stress>Cd2+ stress>Pb2+ stress.The antioxidant enzyme was higher when treated with organic fertilizer than with inorganic fertilizer.The antioxidant enzyme in leaves of Fenghongzao was stronger than Jiangshujiao.[Conclusion] Endurance to heavy metal of Zizania latifolia variety Fenghongzao was stronger than Jiangshujiao.关键词
