摘要

空气污染容忍指数是利用植物来了解任何地区的空气污染程度。植物可根据APTI值分为敏感型、中间型和耐受性。本文研究了比卡尔市选定植物的空气污染耐受指数。通过分析叶片提取物的pH值、抗坏血酸含量(AAC)、叶片总叶绿素含量(TLC)和叶片相对含水量(RWC)等生化参数,计算了不同植物的APTI。结果表明,Khejri (Prosopis cineraria)、Neem (Azadiracta indica)、Babul (Acacia nilotica)、Ber (Ziziphus nummularia)、Aak (Calotropis procera)和Peepal (Ficus religiosa)等植物的APTI值在30 ~ 100之间,对空气污染具有一定的耐受性。曼陀罗(Datura stramonium)的APTI值为21.5,是唯一属于中间类型的物种。建议在国家公路上种植这些植物,以对抗干旱地区的空气污染。这些植物可用于绿化带的开发。

PRELIMINARY STUDIES ON AIR POLLUTION TOLERANCE INDEX (APTI) OF SELECTED PLANT SPECIES IN BIKANER CITY
Air Pollution Tolerance Index is used to find out the level of air pollution in any area with the help of plants. Plants are categorized as sensitive, intermediate and tolerant based on their APTI values. The present study examines the Air Pollution Tolerance Index of selected plant species in Bikaner city. The APTI of various plants have been computed with the values obtained by analysis of biochemical parameters such as pH of leaf extract, ascorbic acid content (AAC), total leaf chlorophyll content (TLC) and leaf relative water content (RWC). It was found that plant species Khejri (Prosopis cineraria), Neem (Azadiracta indica), Babul (Acacia nilotica), Ber (Ziziphus nummularia), Aak (Calotropis procera) and Peepal (Ficus religiosa) showed APTI values in the range of 30 to 100 which are tolerant to air pollution. Datura stramonium was the only species which falls under the intermediate category due to its APTI value of 21.5. It is recommended that these plants can be grown on national highways to combat air pollution in arid areas. Such plants can be used in the development of green belt.
