Abstract: Science for phyto-technologies has got immense application in air pollution science. The present study focuses on the determination of air pollution tolerance indices (APTI) from forty-six tree species of Lalbagh, Bangalore, India. The APTI was determined by synthesizing the four different physiological and biochemical parameters, i.e., leaf relative water content (RWC), ascorbic acid content (AA), total leaf chlorophyll (TCh) and pH of leaf extract. There were total 46 different tree species selected to study Air pollution tolerance index. Among them (Ceiba pentandra) (9.81), Terminalia myriocarpa (9.75), Calliandra brevipes (9.60), Bursera delpechiana (9.37), Saraca indica (9.34), Saroba eoipinaeace (9.30) recorded highest ATPI value compared to Bauhinia acuminata (7.52) Coffea liberica (7.55) Garcinia livingstonei and Ligustrum robustum (7.78) which showed lowest value in ATPI. Remaining species lies under moderate category ranged between 8.02 to 8.86.
