Abstract
The experiment was conducted in the wire house in the Department of Biology, College of Education, Mosul University according to the complete randomized design (C.R.D) to establish the synergetic effect of PBO in overcoming the negative effect caused by drought on the wheat (Ebba-95), by socking the seeds in three concentrations of PBO (0, 20, 40) microliter before culturing, and exposing the plant to two periods of drought after culturing to reveal its impact on the growth of the plant and some physiological aspects and chemical content of that plant. The result showed that drought period had a negative effect on the plant height, leaf area, dry weight of shoot, and root, deficient of water content and total chlorophyll. The second drought period caused decrease in the concentrations of P. K. Ca. Mg by (28.1, 31.7, 22.2 and 20.5%) respectively, compared with the control treatment (without drought). Yet, there was a significant increase in the plant content of proline, sodium concentration with drought. Socking the seeds in PBO led to a stimulation in about qualition, as well as the interaction with drought reduces the negative effect of drought and increases the concentration of the above elements by (45.9, 18.8, 51.7, 39.2 %) respectively, at concentration 40 microliter compared with control. on the other hand, the accumulation of the nutrient elements in the three parts of plant (root, shoot, grain) has the highest concentration of (P, Ca, Mg) appeared in grains compared with root and shoot
