The effects of air pollution on some morphological and physiological characteristics of Platanus orientalis L. leaves in Tehran
Plantain (Platanus orientalis L.)is an important tree used in green space in Tehran. Due to severe air pollution in Tehran, these trees experience early fall in recent years. The present study in an attempt to find the causes of this phenomenon, measured leaf area, dry weight, stomata conductance, s...

| description | Plantain (Platanus orientalis L.)is an important tree used in green space in Tehran. Due to severe air pollution in Tehran, these trees experience early fall in recent years. The present study in an attempt to find the causes of this phenomenon, measured leaf area, dry weight, stomata conductance, stomata resistance, relative leaf humidity, relative chlorophyll concentrations, and the values of calcium, magnesium, lead, and cadmium. Leaves were collected from three regions in Tehran: Sadra Park as a clean region, Al-Mahdi Park as the polluted region 1, and Avesta Park as the polluted region 2. Results showed that air pollution causes significant reduction in leaf area and increase in stomatal conductance in Al-Mahdi Park. The highest amounts of magnesium and lead were also observed in Avesta Park plantain leaves. The highest value of cadmium in leaves was recorded in Sadra Park region. No significant differences were observed in the other traits under study at the collection sites. It seems plantain is able to absorb heavy metals. |
