| 中文摘要 |
| 石化空气污染区树木叶片内的蛋白质、核酸、游离氨基酸及过氧化物酶同工酶含量较对照区有明显的变化,变化 幅度小的树木的抗污染能力强,变化幅度大的抗污能力弱。其中蛋白质、核酸含量表现出降低,游离氨基酸和过氧化物酶同工酶含量升高。供试的几种绿化树木抗污能力由强至弱依次为云杉、旱垂柳、中东杨、白榆、丁香、白蜡槭。 |
| 英文摘要 |
| Obvious changes were observed in the content of protein, nucleic acid, free amino acid and peroxide isoenzyme in woody plant leaves in petrochemical air pollution area compared to the trees in unpolluted areas. The trees with small change in content of above chemicals possess strong pollution-resistant ability. Among the compounds mentined above, Protein and nucleic acid content decreased and free amino acid and peroxide isoenzyme content increased in the polluted tree leaves. The order of pollution-resistant ability of the trees observed is as follows; Picea koraiensis, Salix matsudana, Populus be-rolinensis, Ulmus pumila, Syringa obvata and Acer negundo. |
