Abstract
A study was undertaken to determine the effects of automobile pollution on road side plants Abutilon indicum, Datura metel. Leaf characters such as Leaf area index and Stomatal index and biochemical constitutions such as Air pollution tolerance index, Total Chl, Chl a, Chl b, Protein, Amino acids and Proline respectively were studied. There is reduction in Leaf area index, Air pollution tolerance index, Total Chlorophyll, Chlorophyll a, Chlorophyll b, Protein. Stomatal index, Proline and Aminoacid were increased when compared to control plants. Hence test plants can be used as test material for monitoring the quality of air and conveniently be employed as biological indicators of air pollution.
