| 摘 要： | 研究分析了不同浓度Pb2+对条斑紫菜植物体叶绿素a含量,POD、SOD活性,MDA含量,总抗氧化能力以及可溶性蛋白质含量的影响.结果表明,随着Pb2+浓度的增加,叶绿素a含量,POD、SOD活性,MDA的含量,总抗氧化能力,可溶性蛋白质及均呈先升后降趋势.条斑紫菜对Pb2+具有较高的耐性.

| Abstract: | This paper deals with the effect of different cincentation of Pb~(2+) on chlorophylla content,POD, SOD activity, total antioxicatability, soluble protein contents and MDA centent in Porphyra yezoensis.The results showed that with the increase of Pb~(2+)treatment concetration the chlorophylla content,POD, SOD activity, total antioxicatability,soluble protein contents and MDA content appeared a tendency to first increased and then decreased. Porphyra yezoensis is much endurable to Pb~(2+). |
