Abstract
Copper (Cu) is one of the micronutrients needed by plants which activates some enzymes in plants, also required in the process of photosynthesis is essential in plant respiration and assists in metabolism of carbohydrates and proteins, however excess of copper inhibits plant growth and impairs important cellular process (i,e photosynthesis electron transport). In recent years cu pollution in agricultural soils due to arbitrary use of pesticides, fungicides, industrial effluent. Here we reviewed the adverse effects of cu on Sorghum bicolour was investigated. Copper was applied in the form of copper sulphate (CuSo4.5H20) in four levels (0, 5.0, 10.0 and 15.0ppm. we observed visible symptoms of cu toxicity in this plants. During the exposure of plants to excess copper the antioxidant defense system the plant to protect itself from the damage up to some extent with increasing copper concentration of Ascorbic Acid activites increased in leaves compared with that of control group up to 10.0ppm concentration of Cu. Total phenol content in the leaves showed reduction with increasing cu concentration as compared to control at days. The chlorophyll amount gradually declined with Cu concentrations. There was gradual decrease in the content of phytochemicals. (Tannin, Saponin, Alkoloid).
