Study of Air Pollution Effects on Some Physiology and Morphology Factors of Albizia lebbeck in High Temperature Condition in Khuzestan

S.M. Seyyednejad, M. Niknejad and M. Yusefi    

Abstract: The main purpose of this study is to determine some physiological and morphological characters of Albizia lebbek grown in high temperature condition of Khuzestan in Iran. The location was selected because of high rate of industrial pollution that is caused by petrochemical companies. Albizia lebbeck Benth. is a deciduous tree with compound leaves, flat oblong fruits, round cream colored seeds, grows wild and planted in almost south of Iran. The plant is found throughout tropical and subtropical Asia and Africa. The concentrations of chlorophyll A, B total chlorophyll, carotenoid, soluble sugar, proline and morphological effects were examined in the leaves of tree species (Albizia lebeck), growing in polluted area in comparison with natural condition. In the polluted regions higher concentrations of soluble carbohydrate, proline, chlorophyl A, B, carotenoid were observed in comparison with trees in the unpolluted regions. The morphological characters such as leaf area showed decrease.
