Collecting and Working with Orchid Seeds

David Remucal, University of Minnesota Landscape Arboretum While many seedbanks avoid working with orchids, more groups are taking them on, or collecting them for groups that are. Collecting rules and protocols are not different for orchids but there are enough complexities in their biology to intimidate collectors new to orchids. Orchid seeds are the smallest in […]

The Potential of Shoot Tip Cryopreservation for the Ex Situ Conservation of Oaks.

Screenshot of The Potential of Shoot Tip Cryopreservation for the Ex Situ Conservation of Oaks video

Dr. Valerie Pence, Cincinnati Zoo & Botanical Garden Although there are published protocols for initiating shoot cultures for over 20 oak species, the cryopreservation of oak shoot tips has not been reported. We have applied the droplet vitrification protocol to four species of oaks, including the endangered Q. hinckleyi, in order to evaluate the feasibility of […]

Amy Byrne, The Morton Arboretum A 2019 study by Griffith, et al. showed that gardens must collaborate to conserve genetic diversity, especially for exceptional species whose seeds cannot be conventionally seed banked. This process of capturing the genetic diversity of exceptional species in ex situ collections requires a tailored strategy for each species, emphasizing the need […]

Raising Peas in Rising Seas: How an increase in soil salinity affects seed germination and seedling survival of the Keys partridge pea (Chamaecrista lineata var. keyensis) a rare Florida Keys endemic

Screenshot from Raising Peas in Rising Seas video.

Sabine Wintergerst, Fairchild Tropical Botanic Garden The only known remaining populations of the Keys partridge pea (Chamaecrista lineata var. keyensis) are found within the imperiled pine rockland habitat on two islands of the Florida Keys. Like other low-lying islands, the Florida Keys are especially threatened by sea level rise. As a consequence, soil salinity levels will […]

Anne Frances, NatureServe; Amanda Treher, NatureServe; Wesley Knapp, North Carolina Natural Heritage Program Plants that occur in only one to few locations globally are most at-risk of extinction. Research on the extinct plants of North America shows that 64% of extinct plants were known from one site. Single site endemics generally face higher threats than plants […]

Range-wide Ex Situ Seed Conservation and Population Genetic Architecture Analysis in Venus Flytrap (Dionaea muscipula)

Video screenshot

Dr. Johnny Randall, North Carolina Botanical Garden The infamous Venus flytrap, Dionaea muscipula, found across North Carolina and into South Carolina, has been seen to be declining in recent years. It is currently under review for federal listing, is ranked G2 on NatureServe, and considered vulnerable by RedList. Threats to this charismatic plant include poaching, […]

Jeremie Fant, Chicago Botanic Garden This talk highlights the Chicago Botanic Garden’s work on adapting zoo conservation approaches for exceptional plant species. Challenges in ex situ conservation include genetic issues that arise from limited numbers of individuals and founders, and husbandry and hybridization issues encountered during the growing out of collections. A significant advantage in plant conservation is that seeds can be collected […]
