Pre-treatment: Seeds were collected and stored at ambient conditions before being sealed in a foil envelope and frozen at -4 degrees Fahrenheit. Alternatively, seeds were dried to 15% relative humidity before being sealed in a foil envelope and frozen at -4 degrees Fahrenheit.
Establishment: Seeds were collected in different years (2004 and 2013) and underwent different pre-treatment protocols. The seed bank is searchable at https://www.sciencecollections.org/content/search-collections.
