air pollution tolerance index (apti) and expected performance index (epi) of selected plants at rgsc, (bhu), mirzapur, india

This study carries the evaluation of tolerance of sixteen plants against pollution. these plants have been selected and assessed for several phyto-socio-economic (tree height, canopy, type of tree, laminar structure, hardiness and economic value) and biochemical qualities (ph, relative water content (r), ascorbic acid (aa), chlorophyll a (chl a), (chl b), carotenoids (car) and total chlorophyll (tc)) and tested for air pollution tolerance index (apti) and expected performance index (epi) and then epi score used as grades of plants (not recommended, very poor, poor, moderate, good, very good, excellent and best plus plant). statistical analysis tool like correlation matrix among plant parameters and annoa test has been applied to understand the relationship among plant parameters and plant species. the best epi score means best suited plant for the area for plantation and green belt development while plant with lower epi may be used as bioindicators for the pollution because they are very sensitive for the air pollution.
