Pods of some roadside plants such as Albizia lebbeck, Pongamia pinnata, Dalbergia sissoo, Leucaena leucncephala, Parkensonia aculeata, Sesbania sesban and Tecoma stans collected from the city area showed significant decreases in weight and length as compared to pods collected from a clean area. Azadirachta indica, Delonix regia and Peltophorum pterocarpum showed enhancement in pod weight or length. The seeds of most of the species collected from the polluted areas also showed significant reduction in germination as compared to the seeds of the control area, except Cassia surattensis and Tecoma stans. These two species showed a comparatively higher rate of germination in the polluted seeds. In this germination study the species were found to be resistant in the following order: C. surattensis, T. stans, A. lebbeck, P. pinnata, P. pterocarpum, S. sesban, A. indica, L. leucocephala, P. aculeata, and D. sissoo.
