The aim of the present study is to biomonitor the tolerance level of roadside plant species towards mitigation of air pollution for the development of greenbelt. The leaves of four plant species (Azadirachta indica, Ficus benghalensis, Melia azedarach and Polyalthia longifolia) were collected from 41 sampling sites of Bathinda city during summer and winter seasons. Seasonal variation in APTI and API was determined in selected plants. Highest APTI (13.54) was reported in F. benghalensis during summer and lowest APTI (11.69) in A. indica during winter season. The APTI and API value revealed that F. benghalensis was the best performer, A. indica and M. azedarach were excellent performers and P. longifolia a good performer in greenbelt development to mitigate the air pollution. Pearson’s correlation analysis illustrated significant correlation between APTI, ascorbic acid, total chlorophyll, relative water and pH, respectively.

本研究的目的是生物监测路边植物对缓解空气污染的耐受水平，以促进绿化带的发展。在夏季和冬季，从巴辛达市的41个采样点采集了四种植物物种的叶子（印度印,、榕榕，Mel子和长叶Poly）。确定了所选植物中APTI和API的季节性变化。最高APTI（13.54）据报道，F.火柴头夏季和最低APTI（11.69）在印楝在冬季。APTI和API值表明，孟加拉粉虱（F. benhalensis）的表现最佳，分别是印度粉虱和印度ze。表现优异，而P. longifolia则在减轻空气污染方面的绿地开发方面表现出色。皮尔森的相关分析表明，APTI，抗坏血酸，总叶绿素，相对水和pH分别显着相关。
