摘要
近年来SO2污染比较严重,它对植物有着多方面的影响。目前,SO2单一污染物对植物生理生化的直接影响已比较清楚,但SO2对植物的间接影响以及SO2与其他污染物对植物的复合影响,特别是在分子水平上研究SO2的影响等内容尚不清楚。植物一方面要受到SO2污染的影响,另一方面又对SO2的影响具有一定程度的修复能力。植物细胞保护酶通过清除活性氧在植物的自我修复中起着重要的作用。
Nowadays the pollution of SO2 becomes more and more serious, and it has a wide range of effects on plants. As a only pollutant the direct physiological and biochemical effects are relatively clear. However, the indirect effects and the complex effects with other pollutants, especially the effects on molecular-level are not so lucent. On the one hand plants are influenced by SO2 pollution, and on the other hand they have certain self-repairing ability. The defense enzymes in plants play an important role in self-repairing by removing the active oxygen.
