摘要：

对西伯利亚蓼扦插苗进行不同浓度和不同时间NaHCO₃处理，研究了NaHCO₃处理浓度和时间对西伯利亚蓼叶细胞膜脂过氧化和活性氧清除酶活性的影响。研究表明，NaHCO₃处理浓度分别与过氧化氢酶活性、丙二醛含量和细胞膜透性之间存在极显著正相关性，与超氧化物歧化酶活性之间存在显著正相关性，与过氧化物酶活性之间无显著相关性；不同NaHCO₃浓度处理间，超氧化物歧化酶活性、过氧化氢酶活性及丙二醛含量差异极显著，过氧化物酶活性和细胞膜相对透性差异显著；不同时间的NaHCO₃处理，过氧化物酶活性、过氧化氢酶活性、丙二醛含量及细胞膜透性差异显著，超氧化物歧化酶活性和过氧化氢酶活性差异极显著。

Abstract:

The effect of membrane lipid peroxidation and activity of oxygen scavenging enzymes of Polygon sibricummaterial of Polygon sibricum was studied under different NaHCO₃ concentration and time. The results indicated there was the terminally notable relationship between NaHCO₃ concentration and activity of activities of catalase(CAT), malondialdehyde(MDA) contents and the permeability of plasma; the notable relationship between NaHCO₃ concentration and superoxide dismutase (SOD), no significant relationship between NaHCO3 concentration and peroxides (POD); Under different concentration of NaHCO₃ stress, the activities of SOD and CAT, MDA content and had terminally notability difference, POD and the permeability of plasma had notability difference; under different time of NaHCO₃ stress, the activities of SOD and CAT had terminally notability difference, the activities of POD, MDA and the permeability of plasma had notability difference.

Key words: NaHCO₃, Polygon sibricum, membrane lipid peroxidation, oxygen scavenging enzymes
