Why Plant Cryopreservation Methods Are 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 […]

Why is Plant Cryopreservation so Interesting?

Plant Conservationists have found that many plants are unable to be stored using traditional seed banking techniques. To address this issue, researchers are exploring the use of cryopreservation, the storing of tissues in liquid nitrogen, to preserve exceptional species. In this video scientists Daniela Impe, Christina Walters, and Karin Van Der Walt explain how they […]
