BACKGROUND: Growth regulators are organic substances besides nutrients, synthesized in plants, causing alteration in their cellular metabolism. Synthesis of some plant hormones is adversely affected by environmental factors, which causes restriction on physiological processes of the plant and ultimately, limits their growth potential.OBJECTIVES: This study was designed and implemented with the aim of evaluating foliar application of different amounts of auxin hormone on the physiological traits and seed yield of wheat cultivars.METHODS: Current research was conducted in the crop year of 1400-01 in Ahvaz city according split plot experiment based on completely randomized block design (RCBD) with three replications. The treatments included wheat cultivars at three levels (Chamran 2, Behrang and Mehrgan) and auxin hormone at three levels (including zero or control, 50 ppm and 100 ppm), which were placed in the main and sub plots, respectively.RESULT: The results showed that the difference between cultivars and different amounts of auxin hormone consumption was statistically significant in terms of effect on total dry matter, leaf area index, crop growth rate and seed yield. The mutual effects of cultivars and auxin hormone had a significant effect on seed yield. The highest seed yield (with an average of 490.2 gr.m-2) belonged to the Chamran 2 cultivar and the use of 100 ppm of auxin hormone, and the lowest seed yield (with an average of 360.6 gr.m-2) belonged to the Mehrgan cultivar and no auxin application.CONCLUSION: According to the test results, the use of 100 ppm of auxin hormone compared to other treatments significantly improved the growth and yield of Chamran 2 wheat seeds.
