Bu çalışmada, 7 tescilli ekmeklik buğday (Triticum aestivum L.) genotipinin (Gerek 79, Sultan 95, Haymana 79, Grk/Cty, T98-9, Pastor, PM ME1) fizyo-biyokimyasal parametreleri kuraklık stresi koşulları altında incelenmiştir. Farklı kuraklık şiddetine (3., 6. ve 10. gün) maruz bırakılan bu buğday genotiplerinde polifenol oksidaz (PPO), peroksidaz (POD), askorbat peroksidaz (APX), katalaz (CAT), fotosentetik pigment, toplam protein, hidrojen peroksit, lipid peroksidasyonu (malonildialdehit-MDA) ve prolin seviyeleri belirlenmiştir. Bu çalışma sonucunda, 7 farklı buğday genotipi arasında Gerek 79 ve Haymana 79 genotipleri fizyolojik olarak kuraklığa en duyarlı genotipler olurken, Pastor ve Sultan 95 genotipleri kuraklığa en toleranslı çeşitler olmuştur. Ayrıca buğday çeşitlerinde genel olarak kuraklık süresinin uzamasına paralel olarak oksidatif hasara bağlı olarak fotosentetik pigment içeriğinin önemli ölçüde azaldığı, prolin ve MDA içeriğinin ise arttığı tespit edilmiştir.

In this study, physio-biochemical parameters of 7 registered bread wheat (Triticum aestivum L.) genotypes (Gerek 79, Sultan 95, Haymana 79, Grk/Cty, T98-9, Pastor, PM ME1) were investigated under drought stress conditions. Polyphenol oxidase (PPO), peroxidase (POD), ascorbate peroxidase (APX), catalase (CAT), photosynthetic pigment, total protein, hydrogen peroxide, lipid peroxidation (malonyldialdehyde-MDA) and proline levels were determined in this wheat genotypes exposed to different drought duration (3rd, 6th and 10th day). As a result of this study, among 7 different wheat genotypes, Gerek 79 and Haymana 79 genotypes were the most physiologically sensitive to drought. In comparison, Pastor and Sultan 95 genotypes were the most drought-tolerant varieties. In addition, in parallel with the prolongation of the drought period in wheat varieties in general, it was determined that the content of photosynthetic pigments decreased significantly due to oxidative damage, while proline and MDA content increased
