Abstract

In the present investigation, species like Cassia sophera,Linn., Phaseolus radiatus,Linn., were selected from three different sites (Site-I-Indo American more, Site-II-Hudco and Site-III- Dairy more) of Durgapur industrial township along with a control area(Golapbag more, Burdwan University) . Significant variation was observed among the studied biochemical parameters such as chlorophyll, protein, soluble sugar, ascorbic acid,amino acid, DNA, RNA content of leaves and other plant parts of selected plant species under air pollution stress. Cassia sophera plant exhibits higher level of leaf ascorbic acid and seed RNA content at site-II, reduction in the level of leaf chlorophyll and shoot sugar at site-II in comparison to other sites. At siteĀ—III, Leaf sugar and seed protein content of Cassia sophera showed significant reduction in comparism to other sites. Cassia sophera plant also showed higher level of sugar accumulation in shoot increasing and amino acid at seed in site-III when compared to other sites.Cassia sophera exhibited significant reduction in the level of leaf ascorbic acid and seed amino acid and seed RNA in site-I in comparison to other sites. Phaseolus radiatus plant exhibited higher level of leaf ascorbic acid, leaf sugar, seed RNA in study site - II in comparison to other sites. At site-I level of leaf chlorophyll,shoot sugar,seed protein,and seed DNA of Phaseolus radiatus were found higher in comparism to other sites. Seed amino acid of Phaseolus radiatus at site-I showed significant reduction in comparison to other sites. Phaseolus radiatus revealed higher amino acid content and lesser seed DNA content in comparison to other sites. Air pollution index of control zone exhibits clean air and study site-I, II, III show severe air pollution load.
