Abstract
Conocarpus erectus, Ziziphus jujube, Phoenix dactylifera L., Tamarix aphylla and Albizia lebbeck were chosen in four different areas of Basrah (southern Iraq) and for different times during 2015 to test their tolerance to air pollution, leaves used to estimate the physiological evidence which showed that the low and highest values in December and May respectively, pH values were 4.55-8.67 in Albizia lebbeck and Tamarix aphylla respectively, and values of ascorbic acid 0.08-10.33 mg/g in Ziziphus jujube and Albizia lebbeck respectively, content aqueous leaves were 55.96-98.76% in Albizia lebbeck and Ziziphus jujube respectively, total chlorophyll recorded were 0.01-0.13 mg/g in Phoenix dactylifera and Albizia lebbeck respectively, while the lowest and highest values of air pollution index were (6.42-14.18) in Albizia lebbeck during December and May straight as well. The rise in temperature had a role in raising the sensitivity of plants to air pollutants, and the data showed the variance of values, which is due to the variation of air pollution.
Key words: pH, Ascorbic acid, Relative water, Chlorophyll, Air pollution.
