查询词典 NR

MDA content, cell division , he activities of NR, CAT, POD and SOD of Pistia sagittifolia and Myriophyllum Spicatum with heavy metal,s ion concentration to appear a trend of ascending firstly and desending secondly . This trend explains that Pistia sagittifolia and Myriophyllum Spicatum on the Toxic Effects have similarities under handing the single Pb2+ and Hg2+. As the range of the concentration which each index is arriving at the maximum is different, this also indicates that there are some differences of the Toxic Effects between Pistia sagittifolia and Myriophyllum Spicatum under handing the single Pb2+ and Hg2

丙二醛含量、脂膜透性、硝酸还原酶活性、过氧化物酶活性、超氧化物歧化酶活性、过氧化氢酶活性随重金属离子浓度的增加呈先升后降趋势，说明在单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有相似性；但各指标到达最大值的浓度范围不同，又说明单一Pb2+和Hg2+处理下大薸和穗状狐尾藻毒害效应具有差异性。
