Physiological changes and biochemical aspects due to impact of air pollutants on mustard plants
Author(s): Nidhi Kumari
Abstract: Pollutants due to rapid industrialization eg - refining of petroleum product exerts stress on growth & development of mustard plant. Biochemical indicator of stressful environment were noted in mustard plant. Major pollutants liberated as a result of refining of petroleum products at Baruni Oil Refinery are SO2, NO2, suspended particulate matter (S.P.M) & other harmful substances. SO2 & NO2 together have synergistic effect causing more injury to plants. Pollutants impair normal metabolism of plants causing physiological and Bio-chemical changes in mustard plants. Pollutants in impair normal metabolism of plant causing physiological and bio-chemical changes in mustard plant. Chlorophyll is the major component in photosynthetic metabolism of plants. Increase level of SO2 oxidizes chlorophyll pigments in presence of peroxidase enzyme, thereby reduction in the level of chlorophyll of leaves hindering the photosynthetic metabolism. Peroxidase is involved in cellular growth of plant. Increase in peroxidise activity is an indicator of stress environment created by pollutants. Catalase enzyme level is decreased at polluted site which further leads to accumulation of H2O2, which in term oxidizes chlorophyll pigment thereby reduction in chlorophyll level. If the level of pollutants crosses the threshold value of plant resistance then it will be finally cause injury to plants leading productivity loss.
