Pteridophytes, the first land plants with vascular system are facing numerous threats including habitat degradation and climate fluctuations due to their specific microclimatic requirements. The increasing demand for pteridophytes as ornamental plants and medicinal resources has resulted in their depletion from natural ecosystems, highlighting the need for innovative conservation techniques such as in vitro propagation. This review consolidates existing research on the effects of phytohormones on pteridophyte propagation, providing insights into optimal hormone combinations and concentrations for successful in vitro culture. Additionally, it highlights the importance of considering species-specific variations and the influence of environmental factors in designing effective propagation protocols. Understanding the hormonal requirements and responses of pteridophytes during in vitro propagation is crucial for conservation efforts, sustainable utilization, and the establishment of large-scale production systems. Further research in this field can contribute to the preservation and commercialization of threatened pteridophyte species while reducing the pressure on their natural populations.
