Sedum alfredii Hance, a newly discovered hyperaccumulator, could serve as a good material for phytoremediation of Cd polluted sites. Malondialdehyde (MDA), reactive oxygen species (ROS) and antioxidases (catalase (CAT);superoxide dismutase (SOD);peroxidase (POD)) in the leaf were determined when S. alfredii was treated for 15 d with various CdCl2 concentrations ranging from 0 to 800 μmol/L. The results showed that the production rate of 20,70-dichlorofluorescein (DCF), which is an indicator of ROS level, reached up to the maximum at 400 μmol/L CdCl2 and then declined with the increase of...

景天属的植物 alfredii Hance，一个最新发现的亢奋的蓄电池，能为 Cd 的植物救治用作好材料弄脏的地点。Malondialdehyde (MDA ) ，反应的氧种类(ROS ) 和 antioxidases (过氧化氢酶(猫) ；超级氧化物 dismutase (草皮) ；过氧化物酶(邮政部门)) 在叶被决定是否 S。alfredii 为 15 d 被对待，各种各样的 CdCl2 集中从 0 ～ 800 μ m ol/L 。结果证明 20,70-dichlorofluorescein (DCF ) 的生产率，是 ROS 水平的指示物，在 400 μ m ol/L CdCl2 到达了直到最大值然后随 CdCl2 集中的增加衰退了，当 MDA 累积趋于增加时。猫活动显著地被禁止根本测试的 CdCl2 集中和草皮活动严厉地在 800 μ m ol...
