Storage Behaviour

Storage Behaviour: Orthodox
Storage Conditions: 1% germination after more than 15 years open storage at room temperature (Harrington, 1972); p50= 13.12 years for seeds under open storage in a temperate climate (Priestley, 1986); long-term storage at CIAT (Hanson et al., 1984), under IPGRI preferred conditions at RBG Kew, WP. Oldest collection 2 years
