Abstract

A comparative study on tolerance to Sulphur dioxide exposure was made on two species -Mimusops elengi (E) and Ficus religiosa (D) by exposing young plants to different concentrations of sulphur dioxide. It was found that the degree of foliar injury was directly proportional to the concentration of pollutants.  Decrease in root-shoot length,  fresh and dry weight,  photosynthetic pigments and ascorbic acid was recorded in plants exposed to the gas,  while high level of sulphate was recorded in their leaves.  Both species exhibit identical trend.
