Air Pollution Tolerance Levels of Selected Urban Plant Species in Industrial Areas of Hyderabad (A.P), India

Uma Devi Randhi, Dr. M. Anji Reddy

Abstract :

By computing the four foliar biochemical features i.e. Ascorbic acid, Total Chlorophyll content, Relative Water Content and Leaf extract pH together in a formulation, it signifies the Air Pollution Tolerance Index (APTI) of plants. Of the 16 plant species analysed two tree species such as Delonix regia Hook. exhibited higher APTI value. Clerodendrum paniculatum L., Samania saman Jacq. and Azardirachta indica A. Juss. showed intermediate tolerance capacity and the other plant species Syzygium cumin L.i, Terminalia catappa L., Millingtonia hortensis L.f., Terminalia arjuna Roxb., Pongamia pinnata L., Polyalthia longifonia Sonn. and Emblica officinalis Gaertner., Swietenia mahagoni L. and Saraca indica L. The remaining plant species, Peltophorum pterocarpum DC., Alestonia scholaris L., Ficus religiosa L., acts as bio-indicators of air pollution stress as these are sensitive to the air pollution.
