This study investigated the effects of Indole Butyric Acid (IBA) and Naphthalene Acetic Acid (NAA) on air-layered pomegranate plants. The results showed that IBA application significantly reduced days to first sprouting, increased shoot length, number of leaves, shoots, and branches, and improved shoot girth and plant height. The optimal IBA concentration and duration of application were found to be 2000 ppm and 45 days, respectively. The study suggests that IBA promotes cell elongation, cell division, and carbohydrate synthesis, leading to increased shoot growth and branching. The findings are consistent with previous studies, which reported similar effects of IBA on air-layered pomegranate plants. The success percentage of 85.09% after 90 days of transplanting indicates the potential of IBA application in improving air-layering techniques. The study's results have significant implications for pomegranate cultivation, offering a viable method for rapid plant multiplication and increased productivity. The optimal IBA concentration and duration of application may vary depending on the cultivar and environmental conditions, highlighting the need for further research. Overall, the study demonstrates the efficacy of IBA application in enhancing shoot growth and survival in air-layered pomegranate plants, and provides valuable insights for improving air-layering techniques in pomegranate cultivation.
