| Abstract | ||
| The experiment has been conducted in a greenhouse at the University of Mosul - Republic of Iraq, to study the effect of Glycine betaine(GB) on stressed and water-balanced wheat, and the study included three factors: the first factor is two cultivars of wheat, the second factor is water stress using (PEG-6000) (0, -0.6,-1.2 MPa), the third factor is GB (0,100 mmol l-1), and the following traits were studied: CAT, SOD, APOX and RWC in the flag leaf, plant yield, Dry plant weight and harvest index%. The Exogenous of GB improved the resistance of two cultivars to water stress and led to A significant increase in RWC, CAT, SOD, APOX, grain yield and Dry plant weight in the absence and presence of water stress, and GB encourages plants to trend in seed formation and convert the substances they produce into grains. Water stress caused an increase in CAT, SOD, APOX, decreasing RWC. | ||
