Abstract :Wheat is a staple food that plays an important role in human nutrition. It is one of the most widely grown crops in the world and can be grown in a variety of climates and soil conditions. Wheat plants need nitrogen for their growth and yield. Nitrogen deficiency in wheat can lead to poor plant growth, yield reduction, and decreased protein content. Wheat plants also need to take up adequate nutrients to produce strong roots and seedlings, especially after germination. In this study, conducted in the Field Crops Department of the Faculty of Agriculture at Ordu University in 2023, the effects of different nitrogen fertilizer doses (1.5%, 2%, 3%, 4%, and 5%) on wheat seed germination were determined, and at the same time, the stoma structures located on the underside of the first leaves of the germinated seedlings were imaged with SEM microscopy. The root/shoot length ratio, seedling and root fresh weight, shoot/root, and root/shoot weight ratio were found to be significant (p<0.05). According to the results, the germination rate of various nitrogen treatments varied from 43.33 to 96.7%, while the control application was 33.33%. The application of 0.04 yielded the highest germination rate. The control group exhibited the lowest rate of germination. The LSD means for the majority of parameters, including seedling length, root length, shoot length, root/shoot length ratio, shoot/root length ratio, and seedling fresh weight, were highest for nitrogen administrations of 0.04 and 0.05. In contrast, the LSD means for these parameters were lowest for the 0.02 nitrogen application. A number of parameters, including seedling length, root length, shoot length, root-to-shoot and shoot-to-root length ratios, seedling and shoot fresh weights, shoot and root dry weights, and shoot water content, showed significant differences in germination characteristics under different nitrogen doses. The study\'s results revealed that the differences in stoma structures formed in young leaf tissues were striking when examined under SEM.Keywords : Azot, Çimlenme, SEM, Triticum aestivum L.
