The recovery of cryopreserved buds of cv. Brödtorp in vitro. Top row: the propagule excised from a non-rehydrated bud (a) 2 weeks after initiation of in vitro culture (photo Dr. Mauritz Vestberg) and (b) 10 weeks after initiation. Bottom row: the propagule excised from a bud rehydrated 11 days (c) 2 weeks after initiation of in vitro culture (photo Dr. Mauritz Vestberg) and (d) 10 weeks after initiation. Bud sections of cv. Brödtorp were cryopreserved without pre-desiccation and revived from cryostorage via fast thawing. Images a and c were taken on graph paper through a stereomicroscope.
