Change Total Flavonoid and Some Trace Elements Contents of two Iraqi Wheat Species after Spraying Pallas 45 OD Herbicide .

Abstract

An important plant ; wheat  which used  daily in human mail,  forms a major content of bread and pasta. Wheat is known as a rich source for phenolic, flavonoid, and some trace elements that considered as antioxidant contents. These contents are mainly contributed in protection from degenerative diseases that are stimulated by reactive species. The aim of this project was to study the effect of Pallas 45 OD herbicide on the phenolic, flavonoid, and some trace elements contents of Wheat.In this work,Wheat seeds (cultivar Abu Ghraib 3= group 1;G1 ,and cultivar Iba 99  = group 2;G2) , they are sprayed with  Pallas 45 OD herbicide (125 mL/donum), the samples (with and without spraying ) harvested after 5and 100 day .Aflame Atomic Absorption Spectrometry was used for measurements of  Mn, Cu, and Zn concentrations after digestion of wet samples also Total phenols  was measured using folin method .Results show the antioxidants that measured in this work were negatively influencedbyPallas 45 OD herbicide treatment. This effect was obviously appearance by the significant dropped in most of the levels  ofantioxidants. Therefore, wheat products after treating with Pallas 45 OD herbicide would be less in healthy levels and it would be beneficial to thinking to prepare  an alternative solution to obtain good products of this important wheat with elevate yield.  xz
