APTI of Some Selected Plants in Shivamogga City, South Asia

Abstract

Air pollution is the human introduction into the atmosphere of chemicals, particulate matter or biological materials that cause harm or discomfort to humans or other living organism or damage the environment. The study examined air pollution indices (APTI) of fourteen plant species around Shivamogga city of Karnataka State India . Four physiological and biochemical parameters, leaf relative water content (RWC) , ascorbic acid (AA), total leaf chlorophyll (TCH), and leaf extract PH were used to compute the APTI values. The result showed that combining variety of these parameters gave more reliable result than those of individual parameter. The order of tolerance is as follows: Azadirachta indica, (37.74), Mangifera indica (28.4), Eucalyptus mysoresins (27.93), Carica papaya (24.62), Ricinus communis (22.46), Polvalthia longifolia (20.76), Calotropis gigantean (19.84), Nerium indicum (18.49), Psidium guajava (17.51), Parthenium hysterophorus (14.91), Bougainvillea glabra (13.35), Muntingia calabura (11.68), Terminalia cattapa (10.71) and Tamarindus indica (9.12).
