摘要
以来自加拿大的两种高羊茅(Festucaarundinacea)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。
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.
