Effect of Lead Chloride on Biochemical Attributes of Tinospora cordifolia

Accumulation of heavy metals in soils is caused by different man-made activities including manufacturing, agricultural, mining, and waste removal practices. These metal ions dissolved in irrigation water contaminate the cultivated soils and initiates toxic impact on living system when their concentration in soil is high. Lead (Pb) is one of the most important heavy metals frequently available in the environment. In plants, its accumulation has been reported in stem, leaves, roots and seeds, which increases with increase in Pb levels in the growth medium. Lead influences plants by hampering a variety of physiological processes including nutrient uptake. Present study was conducted to investigate toxic effects of PbCl2 on biochemical attributes of Tinospora cordifolia. Plants were treated with different PbCl2 concentrations. The results of this experiment showed that the PbCl2 stress decreased the biochemical contents such as chlorophyll, carbohydrate and proteins in all the treated plants. So PbCl2 as a heavy metal has detrimental effect on Tinospora cordifolia physiology.
