الاستجابة الفسلجية لنبات الحنطة النامي في تربة ملوثة ببعض العناصر الثقيلة

Abstract EN

The study was conducted at the University of Mosul, College of Education , Biology Dept .

to study the effect of soil pollution with heavy metals (Cadmium , Lead , Nickel and Zinc )each one separately in a concentration of (1.00) mM/kg of soil.

By applying on 3 cultivars of wheat (Umm Rabee”, Al-waha, Corfella).

Was studied directed to measure the growth, and other physiological .aspects of the wheat plant : (Triticum aestivum L.).

The results shows that addition of (Cadmium, Lead, Nickel and Zinc) to the soli caused decrease in plant growth ,As the decrease in dry weight of shoot plants and root plants.

The results proved reduced leaf relative water content and the degree of stability of cytoplasmic membrane whith an increase in the proline accumulation in the leaf tissues.
