Effects of copper on seed germination and seedling growth performance of Lens culinaris Medik.

The discharge of heavy metals in the environment due to anthropogenic, industrial and automobile activities is a worldwide environmental pollution problem. Copper is widely used in different forms in fertilizer, fungicides. Industrial effluents and for the removal algal growth in ponds. In this study the toxic effects of copper (Cu) on seed germination and seedling growth of Lens culinaris were investigated. Germination rate of L. culinaris that showed that increased in concentration of copper treatment at 25 ppm significantly (p<0.05) reduced germination percentage as compared to control. Seedling growth variables i.e. root and shoot length, seedling size and root/shoot ratio also declined significantly (p
