Storage Behaviour

Storage Behaviour: Orthodox
Storage Conditions: No problem for long-term storage under IPGRI preferred conditions, seeds tolerate desiccation to 1.8% mc, LMCL= 4.1%, Cw= 5.02 (Ellis et al., 1988); long-term storage under IPGRI preferred conditions at RBG Kew, WP. Oldest collection 10 years; germination change 100 to 96%, 8 years, 1 collection
