Effects of heavy metals stresses on growth, heavy metal and mineral uptake in Caldesia grandis(重金属胁迫对宽叶泽苔草生长、重金属及养分吸收的影响)
盆栽试验以宽叶泽苔草（Caldesia grandis Samuelsson ）为材料，采用500 µmol • L-1 Cd、500 µmol • L-1 Cr、500 µmol • L-1 Pb、1 000 µmol • L-1 Cu溶液处理，研究重金属胁迫对宽叶泽苔草生长、重金属及养分吸收的影响.结果表明：宽叶泽苔草对重金属毒害具有很强的抗性，各种重金属胁迫下植株地上部并未表现出失绿或坏死等中毒症状；重金属Cd、Cr、Pb和Cu处理，分别显著提高根和地上部茎叶中Cd2+、Cr6+、Pb2+和Cu2+质量分数；Cu处理显著增加植株Mn2+质量分数，减少地上部Fe3+质量分数；Pb处理显著增...
