Response of Yield and Yield-Related Traits to Exogenous Foliar Application of 6-Benzyladenine (6-BA) in Wheat SAYED ALI EMAMI1*, ALI SOLEYMANI2 1-PhD Student of Islamic Azad University of Khorasgan, Iran. 2- Department of Agronomy and Plant Breeding, Institute of Agricultural Water, Food and Nutraceuticals, ISF. C., Islamic Azad University, Isfahan, Iran. *Corresponding author’s E-mail: dr.s.a.emami110@gmail.com Received: 5 October 2024 Accepted: 25 January 2025 ABSTRACT Cytokinins are a class of plant hormones that play a pivotal role in regulating growth and development by promoting cell division, delaying senescence, and enhancing stress tolerance, thereby influencing key physiological processes that determine plant productivity. Wheat is a crucial crop that significantly contributes to global food security. This study investigates the effects of foliar application of the synthetic cytokinin 6-benzyladenine (6-BA) at three distinct concentrations 15, 30, and 45 ppm over two consecutive growing seasons (2016-2018) at a research farm located in Barsian village, Ziar on wheat cultivar M7318, aiming to evaluate its impact on yield and yield-related traits, including grain yield, 1000-grain weight, biological yield, harvest index, and grain weight per plant, with the objective of identifying optimal application strategies to enhance wheat. The results reveal a clear trend of increasing grain yield and 1000-grain weight with rising 6-BA concentrations, peaking at 45 ppm, though the improvement plateaus with no significant difference between 30 and 45 ppm, while biological yield significantly increases only at 45 ppm, harvest index declines at this higher dose, and grain weight per plant reaches its maximum at 30 ppm, highlighting the concentration-specific effects of 6-BA on wheat performance. These findings underscore the potential of cytokinin hormones, particularly 6-BA, in wheat cultivation as a sustainable approach to boost yield, offering a promising avenue for precision agriculture by tailoring application rates to optimize grain production and biomass allocation.
