Effects of pollution of growth of mustard plant

Abstract

The Study aimed to appraise the effect of different air pollutants viz SO2, NO2, SPM on growth of mustard plants growing at polluted sites near to Oil Refinery & at reference site (far from polluted site). Air pollution has become a serious environmental stress to mustard plants due to increasing industrialization. Pollutant impair photosynthetic activity, suppress growth parameters, foliage injury & finally growth reduction of plants measured as height of plants, Leaf area, dry shoot & root weight. Comparative study of the above growth parameter were investigated at polluted & reference site near Barauni Oil Refinery. The polluted site atmosphere contains high amount of SO2, NO2 & SPM in comparison to reference site which finally crossed the threshold resistance of mustard plant exerting injurious effect on plant.
