Resistant reaction of Canna indica and Scindapsus aureum to Cr(Ⅵ) stress in purifying eutrophication water(美人蕉和绿萝在修复富营养化水体过程中对Cr(Ⅵ)胁迫的生理生化响应)
研究了陆生植物美人蕉(Canna indica)和绿萝(Scindapsus aureum)在修复富营养化水体过程中对不同质量浓度Cr(Ⅵ)胁迫的生理生化响应.结果表明,Cr(Ⅵ)胁迫影响植物生长,Cr(Ⅵ)质量浓度为10 mg • L-1时两种植物生长明显受到抑制.Cr(Ⅵ)质量浓度为2 mg • L-1时促进美人蕉及绿萝可溶性蛋白质的合成,提高了美人蕉及绿萝SOD、CAT、POD活性,对两种植物MDA积累无明显影响;当Cr(Ⅵ)质量浓度5 mg • L-1时抑制美人蕉和绿萝可溶性蛋白质合成及绿萝CAT活性,提高美人蕉SOD、CAT、POD及绿萝SOD、POD活性,对美人蕉MDA积累影响不大...
