Storage Behaviour

Storage Behaviour: Orthodox
Storage Conditions: No loss in viability following 15 years storage at 35-40% r.h. and 4C (Bass, 1980); viability is halved after 7 years storage under laboratory conditions (Priestley, 1986); long-term storage under IPGRI preferred conditions at RBG Kew, WP. Oldest collection 3 years
