Germination and storage behaviour including cryopreservation of Champerela manillana and Schefflera octophylla seeds were studied. Freshly harvested, mature seeds of both species germinated >90% after three weeks incubation at 30/20°C. Seeds of C. manillana survived desiccation to 5.6% moisture content (MC) (fresh weight basis) during storage at 4°C for 18 months without loss of germinability, whereas the seeds desiccated to 11.3% MC decreased germination percentage from 94.7% to 70% during storage at the same condition. Viability of C. manillana seeds with a MC ≥ 5.6% decreased more rapidly during storage at 15°C than at 4°C. Survival of seeds stored at -20°C was lower than that of seeds stored at either 4 or 15°C. However, maximum viability with a MC of 5.6% was maintained in liquid nitrogen (-196°C) storage after 12 months. These characteristics of C. manillana seeds can be considered as intermediate storage behaviour. Seeds of S. octophylla survived desiccation to 6-7% and -20°C storage for 24 months without loss of viability. Seeds of this species with a MC ≤ 6.2% also survived in liquid nitrogen, whereas viability was reduced to about 50% of that of seeds originally dried and not stored in liquid nitrogen. Considering the sensitivity of seeds of this species towards lower desiccation (< 6% MC) at -20°C and decrease of viability during the 24-month storage, the seeds of this species can probably be categorized as having an intermediate storage behaviour.
