Effect of cement dust pollution on germination and growth of groundnut

Abstract

Air pollution has been described as an additional stress on plants since they often respond to atmospheric contamination in the same way as they respond to drought and other environment stress. The role of air pollutants causing injury to plants either by direct toxic effect or modifying the host physiology rendering it more susceptible to infection. In severe case of pollution, the injury symptoms were expressed as foliar necrosis or completely disappearance of the plant. In that way the present research work carried out cement dust pollution on germination growth and biochemical of groudnut. The cement dust artificially sprayed on the plant surface with different levels. All the morphological and biochemical were analyzed. Morphological parameters Root length, Shoot Length,  and dry weight were inhibited in high dose of cement deposition when compare control plant. The highest amount of all biochemical content which present in control set and lowest one recorded in 25g/pot sprayed with cement dust.
