Storage Behaviour

Storage Behaviour: Orthodox
Storage Conditions: Afew seeds survive following 81 years in herbarium (Turner, 1933); hermetic air-dry storage at 5°C recommended (Gill & Pogge, 1974); 90% germination following 12 months hermetic air-dry storageat 5°C (Grime et al., 1981); long-term storage under IPGRI preferred conditions at RBG Kew, WP. Oldest collection 15 years; germination change 94 to 95%, 14 years, 1 collection
