Abstract
Abstract
This study was undertaken for determining the adverse effects of automobiles released pollution on physio-biochemical aspects of Calotropis procera plant leaves collected from two major roads i.e. M-4 (Faisalabad to Gojra Motorway) and GJR (Gojra-Jhang Road GJR). Significant inhibitory changes were noted in total soluble proteins (25%, 28%), photosynthetic rate (20%, 67%) and transpiration rate, (55%, 69%) of C. procera plant whereas, their total soluble sugars (103%, 37%), total flavonoids content (0.5%, 6%) and total free amino acids (86%, 107%) got increased on both M-4 and GJR roads respectively. More traffic density was recorded along GJR as compared to that on M-4. A positive correlation was recorded for total soluble sugars, total flavonoids content and total free amino acids, whereas, a negative correlation for total soluble proteins, photosynthetic rate and transpiration rate, with traffic density. Over all conclusion C. procera the physio-biochemical changes may be due to traffic related emissions on roads.
Key words: Automobiles, physio-biochemical, flavonoids, inhibitory, traffic density.
