摘要
研究了在不同浓度的铜处理下,两种来源野胡萝卜(矿区:湖北铜绿山铜矿;正常土壤:湖北武汉严西湖)膜脂过氧化水平和生长情况.结果表明:在相同浓度的铜处理下,非矿区种的丙二醛(MDA)、氧自由基以及过氧化氢含量明显高于矿区种,显示非矿区种体内膜脂过氧化水平较高,受到较严重的过氧化伤害;矿区海洲香薷更能耐受铜胁迫,矿区种已经形成了抗性生态型.
Daucus carota L. is the most widely distributed copper- tolerant plant in the area along the middle and lower streams of Yangtze River, China. Choose two populations of Daucus carota L. (one from mining area, Tonglvshan;the other from normal soil, Wuhan, all in Hubei province, China). The result showed that, Daucus carota L. from normal soil accumulate more MDA compared with plant from mining area. It suggested that Daucus carota L. from mining area has been evolved to copper tolerant ecotype.
