Sulphur dioxide is well recognized phototoxic air pollutant and can also be utilized as a potential source of sulphur for plants growing in sulphur deficient soils. It is unique among the gases for acting as nutrient and as well as a toxic agent. Thus assessments of plant responses to sulphur dioxide must consider positive as well as negative impacts.sulphur dioxide will achieve a maximum growth rate at a concentrations which are close to the metabolic requirements of the plant, however toxicity will occur at concentrations above the metabolic requirements. This study assessed the plant...
