- Abstract:
- Physiological and ecological impacts on four urban green plants in differently air polluted cities in Hebei Province were compared by using the modulated chlorophyll fluorometer (PAM Fluorometer). The results were as follows. The sequence of integrate pollution index was Shijiazhuang > Xingtai > Handan > Tangshan > Zhangjiakou, and the concentrations of SO2 and NOx were increasing year by year, which showed the order: Shijiazhuang > Xingtai > Handan > Tangshan > Zhangjiakou in the same year. The carotenoid and chlorophyll contents of urban green plants showed the sequence:Prunus triloba > Cinnamomum camphora > Albizia julibrissin > Fraxinus chinensis, and the cell membrane penetration urban green plants showed the order: Prunus triloba < Cinnamomum camphora < Albizia julibrissin < Fraxinus chinensis, The soluble protein and soluble sugar contents in Prunus triloba and Albizia julibrissin were higher than those in Cinnamomum camphora and Fraxinus chinensis.The free proline and malondialdehyde contents were lower in Prunus triloba and Albizia julibrissin than those in Cinnamomum camphora and Fraxinus chinensis, which indicated that Cinnamomum camphora and Fraxinus chinensis were more seriously afffected by the air pollution. Fv/Fm, Fv/Fo, qP and ΦPSⅡ of Prunus triloba and Albizia julibrissin were higher than those of Cinnamomum camphora and Fraxinus chinensis, and qN of Prunus triloba and Albizia julibrissin were lower than those of Cinnamomum camphora and Fraxinus chinensis, and qN had no significant difference (p > 0.05). When the module SO2 and oxidative stresses were conducted by treating the leaves of these four plants with 5 mmol/L NaHSO3 or 10 μmol/L methyl viologen, the same pronounced increase in cell membrane leakage rate and degradation of chlorophyll were observed. The results indicated that Cinnamomum camphora and Fraxinus chinensis cell membrane penetration were very serious, Cinnamomum camphora and Fraxinus chinensis were sensitive to air pollution and had a lower tolerance to air pollution. So, controlling the sources of pollution emission was the key to control the air pollution in Hebei Province and even the whole country, and important measures must be given great attention to improve urban greening landscape.
