Abstract:

The increasing anthropogenic activity intensifies the emission of various pollutants into the environment and introduces different types of harmful substances into the atmosphere. Air pollution is aesthetically offensive and can be a genuine health hazard to humans as well as to plants. The present paper describes air pollution effects on some physiological and morphological characteristics of Eucalyptus camaldulensis Dehnh. Leaf samples were collected from Gamboeh park in southwest Ahvaz (clean region) and Foolad industrial company of Ahvaz (polluted region), southwest Iran. The morphological and physiological characteristics such as leaf area, stomata number, length of leaf and petiole, width of leaf, levels of chlorophyll a, chlorophyll b, total chlorophyll and carotenoids, soluble carbohydrate rates and proline were investigated. The results showed that the amount of chlorophyll a, chlorophyll b, total chlorophyll, carotenoids, soluble sugar and proline in Eucalypus camaldulensis increased in polluted region. In addition, the morphological traits of Eucalypus camaldulensis leaves were reduced in polluted area compared with clean region.

Keywords:

Air pollution, chlorophyll, soluble sugar, proline, Eucalyptus camaldulensis
