Study on Copper Induced Changes in Pennisetum and Trigonella Seedlings

The objective of the study is to observe the influence of Copper on the growth of 10 day old seedlings ofPennisetum and Trigonella. Seeds were collected from the local seed market, selected and sterilized. The seeds were made to germinate in different concentrations of copper (as copper sulphate) i.e., 0.5, 1.5, and 3mM. The growth of roots and shoots were observed in both the plants. The biochemical analysis for the peroxidase activity, and the contents of ascorbate, glutathione and alpha tocopherol in the roots and shoots of both the plants were observed. The study revealed that there has been an increased production of enzymatic and non-enzymatic antioxidants due to copper stress in both plants and also inhibition in growth and biomass accumulation.
