Gymnema sylvestre Pollinia Cryopreservation
摘要
Gymnema sylvestre, a medicinally valuable plant known for its therapeutic properties, exhibits distinct floral characteristics and phenological patterns, making it an ideal candidate for pollinia cryopreservation. The species produces small, pale-yellow flowers arranged in corymbose cymes, with a pubescent calyx, campanulate corolla, and a fleshy corolline corona. Flowering peaks in August, with anthesis occurring from 7:00 A.M. to 6:00 P.M. and anther dehiscence between 12:30 P.M. and 2:30 P.M., coinciding with peak pollinator activity. Cryopreservation of G. sylvestre pollinia provides a reliable strategy for long-term genetic conservation, ensuring viability and germination potential post-thaw. By storing pollinia in liquid nitrogen (−196 °C), this technique safeguards genetic material for breeding, conservation, and medicinal research. Given the increasing environmental and ecological challenges, cryopreservation plays a crucial role in preserving the genetic integrity of G. sylvestre, promoting sustainable cultivation and future research advancements.
