Abstract:

The circulation of phytotoxic air pollutants from vehicular traffic, industrial factories and geographic location are the main causes of air pollution in Tehran. One of the ways to deal with air pollutants is tree planting in the public roads, parks and green spaces.The Resistance of plants to air pollutants could be evaluated by the value of APTI. Theplant with high APTI value is Resistance to air pollution. The present study was aimed to evaluate the tolerance of Ailanthus altissima (Mill.)Swingle to air pollution in two residential districts of Tehran during spring and autumn 2017. The leaf sampling of the selected trees was conducted in the Punak (area of 5), and Azadi (area of 9). Then leave samples transferred to the laboratory for biochemical analysis. Four biochemical parameters including ascorbic acid content, leaf extract pH, relative water content (RWC) and total chlorophyll content were assessed and APTI value was calculated. The results of this study showed that the Ailanthus altissima (Mill.)Swingle in two seasons spring and autumn in area 9 with higher APTI value (11.65) have significant increase compared to area 5 (with APTI value 9.25). So, Ailanthus recommended being planted in the polluted areas of Tehran.
