摘要

This study evaluates the Air Pollution Tolerance Index (APTI) of 15 plant species in a heavily industrialized area. APTI values were calculated based on 4 biochemical parameters including ascorbic acid content, Chlorophyll content, Relative Water Content (RWC), and pH of leaf extract. The assumption that vegetation improves air quality is leaf extracts, and relative water content. Statistical analysis was performed using Duncan’s multiple range test via SPSS software (v22), and graphical representations were created using Origin Pro. The obtained results revealed that Yucca aloifolia, Phoenix dactylifera, and Punica granatum species had the highest APTI values (15.994, 15.69, and 15.559, respectively), indicating strong tolerance to air pollution. In contrast, Morus alba pendula showed the lowest APTI value (6.066), showing high sensitivity. A significant positive correlation (r = 0.85, p < 0.01) was observed between APTI values and pollutant concentrations during the growing season. Approximately, 60% of the studied species exhibited APTI values above 12, indicating moderate to high resistance to air pollution. Based on these findings, we recommend planting tolerant species such as yucca aloifolia and Phoenix dactylifera to enhance green space development and improve urban sustainability in industrial areas, especially in areas that are ecologically compatible with these species.
