Online published on 30 March, 2022. Abstract Air pollution tolerance index of the native plants were assessed to evaluate their response to tolerance level of pollution by analyzing four biochemical and physiological parameters namely relative water content, pH, total chlorophyll and ascorbic acid content of twenty two plant species during the summer and monsoon seasons during 2016.On the basis of high air pollution tolerance indices the plant species Mangifera indica, Albezia lebbeck, Magnolia champaca, Psidium guajava, Bouganvillea spectabilis, Thespesia populnea and Terminalia catappa are grouped as tolerant. The species Bauhinia varigeta, Tecoma stanus, Tabernaemontana divaricate and Muntinga calabura with low air pollution tolerance indices are grouped as more sensitive to air pollution. The species with high air pollution tolerance index are given importance and suggested for plantation to enhance greenery and to minimize air pollution. This may be technically helpful for air pollution management in the industrial area. Top Keywords Air pollution tolerance index, Native plants, Chlorophyll content, Plantation, Pollution management.
