Effects of copper on seed germination and seedling growth performance of Lens culinaris Medik.
Journal Title: Journal of Plant Development - Year 2018, Vol 25, Issue
Abstract
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<0.05) with the treatment of copper at 25 ppm as compared to control. Seedlings dry weight of L. culinaris gradually reduced with increased in all treatment of copper concentration as compared to control. Tolerance indices and seedling vigor index of L. culinaris also decreased with increase in concentration of copper treatment. Low percentage of reduction in tolerance indices and seedling vigor index of L. culinaris was recorded at 25 ppm copper treatment as compared to control. A high percentage of reduction in seedling tolerance indices of L. culinaris was recorded at 100 ppm of copper treatment as compared to control.
