Abstract EN

The present research was carried out at the University of Mosul /College of Environmental Sciences and Technologies /Department of Environmental Sciences to study the effect of soil pollution with three types of the Heavy metals (Cadmium, Lead, and Copper) each individually at the concentrations (0.01, 0.025, 0.05, 0.1, 0.25, 0.5, 1) mg/L, which affected the germination and vegetative growth and some physiological and anatomical characteristics of the Sabir Baik Wheat (Triticum aestivum L.).

The results showed that adding the heavy metals resulted in significant decrease in growth of plants and relative water content in leaves with a gradual increasing of Proline accumulation in the leaves tissues, Besides the sectional anatomy revealed several changes in the leaves and roots characteristics as a result of the heavy metals effects, in that they changed the size of cells in the cortex and epidermis also the impact on the number of vascular bundles and their distribution in the roots tissues and leave in the wheat plant
