Impact of air pollution on some morphological and physiological characteristics in some evergreen plants in Baghdad city, Iraq

الملخص EN

The present experiment was done to determine the impact of ambient air pollution on some biological factor in Eucalyptus camaldulensis, Albizia lebbeck, Conocarpus erectus plants using one site in Baghdad city.

Various morphological and biochemical characteristics of the plants were studied including(number and density of stomata, number of dust particle,total chlorophyll , leaf area and leaf area index , dry weight, fresh weight, number of filaments, percentage of Pb and Cd ).

Suggesting the activation of protective mechanism in these plant under air pollution stress, and also the plant make physiological adjustments to compensate for that environmental stress.

According to our result Albizia tree are more useful to reduce air pollution than the ether plants under study.However, more research is necessary to evaluate the contribution of individual and in combination of air pollution on crop production and its losses.
