STUDY OF AIR POLLUTION TOLERANCE INDEX (APTI) AND DISTRIBUTION PATTERN BY USING IMPORTANCE VALUE INDEX (IVI) OF PLANTS IN DISTURBED AND UNDISTURBED LOCALITY AROUND ANAND CITY (INDIA)

Air pollution tolerance index (APTI) is mostly used to select plant species tolerant to air pollution. The different physiological and biochemical parameters were used to develop APTI. In the present communication, we represent a comparative study to understand the effect of air pollution on vegetation composition in disturbed and undisturbed community investigated based on Importance Value Index (IVI). This study also suggest that plants have the potential to serve as excellent quantitative and qualitative indices of pollution as biomonitoring of plants is an important tool to evaluate the impact of air pollution on plants. Among the trees Azadirachta indica A.juss showed high degree of tolerance. Such plants species can be used as an important bioindicator and bioaccumulator along with economical importance.
