摘要: 以来自加拿大的两种高羊茅(Festuca arundinacea)为材料, 在温室盆栽的条件下, 研究和比较了不同浓度的二价镉(Cd2+)对两种高羊茅的脂质过氧化程度、保护酶活性和渗透调节物质的影响。结果表明, 与护坡型的高羊茅红象品种相比, 在不同程度Cd2+胁迫下, 草坪型的高羊茅艾瑞品种表现出了更低的脂质过氧化水平、更强的抗氧化保护酶活性和更具适应性的渗透调节水平, 说明高羊茅艾瑞品种对Cd2+的胁迫具有更好的适应性, 修复被重金属污染土壤的能力更强。

关键词: 高羊茅(Festuca arundinacea), 镉, 脂质过氧化程度, 抗氧化酶, 渗透调节物质

Abstract: Two kinds of tall fescue(Festuca arundinacea) from Canada were used as materials to study and compare the effects of different concentrations of cadmium (Cd2+) on lipid peroxidation, protective enzyme activity and osmotic regulators of two kinds of tall fescue in greenhouse. The results showed that, under different concentrations of Cd2+ stress, turf-type tall fescue cultivar showed lower lipid peroxidation level, stronger antioxidant protective enzyme activity and more adaptive osmotic regulation level than slope-protected tall fescue cultivar. It was concluded that, turf-type tall fescue cultivar had better adaptability to Cd2+ stress and stronger ability to repair the soil polluted by heavy metals.

Key words: tall fescue(Festuca arundinacea), cadmium, lipid peroxidation, anti-oxidative enzyme, osmotic substance
