Dennis Whigham, Smithsonian Environmental Research Center Long-term monitoring of Isotria medeoloides at two sites in Virginia have been combined with observations from an understory thinning experiment at one site and death of a large canopy tree at a second site. New plants emerged at both sites following increased light levels and flowering and fruit production increased. […]

Why is Cryopreservation Important to Endangered Native Plants?

Cryopreservation, a method of storing tissues in liquid nitrogen, is becoming increasingly important to rare plant conservation. This is because many plant species, including large groups such as oaks, orchids, and bryophytes, are unable to be stored long term using more traditional seed banking methods. Using cryopreservation techniques, researchers are able to preserve greater crop […]

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 […]

David Remucal, University of Minnesota Landscape Arboretum We have been struggling with a propagation database. This has been of particular interest as our orchid conservation program has grown, we have needed a way to track individual maternal sources or populations from seed to potted plant as they go through different treatments and use different media.

In Vitro Seed Germination and Seedling Development of Spiranthes Casei for Ex Situ Conservation

Screenshot from In Vitro Seed Germination and Seedling Development of Spiranthes Casei for Ex Situ Conservation video

Peter Zale and Matt Taylor, Longwood Gardens Several species of Spiranthes native to the Eastern U.S. are considered rare, threatened or endangered by federal and state agencies. Using the Pennsylvania endangered Spiranthes casei as a model species, experiments were designed to determine optimal conditions for in vitro seed germination and seedling development. Seeds were collected […]
