Storage Behaviour

Storage Behaviour: Orthodox
Storage Conditions: No loss in viability following 2 years hermetic storage at -6C with 6-16% mc (Jones, 1967; Olson & Petteys, 1974); viability can be maintained for several years in hermetic storage at 3C with 5-9% mc (Albrecht, 1993); seeds are maintained in the long-term seed store at DFSC
