Pollen cryopreservation is emerging as a critical technique for conserving the genetic diversity of ornamental and medicinal plants, providing a safeguard against the challenges of environmental stress and limited seed storage potential. This is especially true for species such as Costus comosus and Costus curvibracteatus, members of the Costaceae family, which face increasing threats from habitat destruction and climate change. By collecting pollen under optimal conditions, assessing its viability through in vitro germination, and storing it in liquid nitrogen, this method effectively halts metabolic and biological activities, preventing degradation. Cryopreservation ensures the preservation of valuable genetic material, facilitates controlled pollination, supports hybrid seed production, and maintains important male parent lines, all of which are essential for breeding programs and conservation efforts. While some species show stable or enhanced viability post-cryopreservation, others may experience viability loss, emphasizing the need for species-specific protocols that optimize cryoprotectants and storage conditions. For Costus comosus and Costus curvibracteatus, this approach not only ensures the conservation of their genetic resources but also helps preserve their ornamental appeal and medicinal properties, such as antioxidant and anticancer effects. Advances in cryobiology, including improvements in vitrification techniques and the development of cost-effective protocols, promise to enhance the efficiency of pollen conservation. As environmental pressures continue to threaten plant biodiversity, pollen cryopreservation offers a vital tool to safeguard the future availability of ornamental and medicinal species such as Costus for research, breeding, and restoration initiatives.
