Calotropis gigantea is widely recognized for its medicinal value and belongs to the Apocynaceae family. The flowers form clusters in shades of white and lavender, featuring five petals and a central crown of stamens. The presence of pollinia plays a crucial role in fertilization. In Ayurveda, it is known as “Sweta Arka” and is primarily used to treat various ailments. C. gigantea is a valuable plant in traditional medicine, agriculture, and environmental restoration. Cryopreservation is a vital technique for preserving the genetic diversity of this species, particularly in the face of habitat loss, climate change, and overharvesting. This method allows for the long-term storage of plant germplasm (such as seeds, embryos, or other tissues) at ultra-low temperatures, typically at −196 °C using liquid nitrogen. In vitro germination of pollinia in C. gigantea is a specialized technique that advances plant breeding, conservation, and reproductive studies. Successful germination depends on factors such as the appropriate growth medium, optimal environmental conditions, and precise handling of pollinia. Pollinia germination is typically carried out in B&K medium supplemented with 15% sucrose. Viability assessments can be performed using Alexander stain. The long-term storage of pollinia in liquid nitrogen enhances breeding potential, supports the fertilization process, and facilitates the development of hybrid varieties.
