摘要: 本试验研究了鳞毛蕨科两种植物革叶耳蕨(Polystichum neolobatum)和黑足鳞毛蕨(Dryopteris fuscipes)在不同浓度Cd-Pb复合胁迫下保护酶活性的变化。结果表明,革叶耳蕨POD、SOD、CAT活性与处理浓度呈正相关趋势,即随着处理浓度升高,酶活性明显升高;黑足鳞毛蕨POD、SOD及CAT活性表现出在高浓度(600+1200 mg/kg)处理下受抑制,而在低、中浓度(200+400 mg/kg、400+800 mg/kg)处理下表现为促进作用。

Abstract: Fern is an old fibrovascular plant and also a unique species in the evolution of botany system.The active change of the protective enzyme of Polystichum neolobatum and Dryopteris fuscipes under the compound stress of different Cd-Pb concentrations was studied in this article.It was discovered that the activeness of Polystichum neolobatum's protective enzymes, POD, SOD and CAT, had a positive collaboration with the given concentration.In other words, with the increasing of given concentration, the activeness of enzyme also increased evidently.The activeness of Dryopteris fuscipes' protective enzymes, POD, SOD, CAT, was repressed in the given concentration of 600+1200mg/kg, while was promoted in 200+400mg/kg and 400+800 mg/kg.

Key words: compound stress, lead, cadmium, protective enzyme, influence
