Abstract

Seed viability was maintained in four cultivars of oil palm (Elaeis guineensis Jacq.) during 12 months of hermetic storage at 15°C with 10–12% moisture content (embryo moisture contents of 19–21%). The viability of both these and drier seeds was reduced greatly during this period at cooler storage temperatures of 0°C and −20°C, however. For example, intact seeds at 6.1–7.4% moisture content (embryo moisture contents of 9.1–12.0%, at which freezing damage would not be expected) lost viability more rapidly at 0°C and −20°C than at 15°C. Moreover, desiccation to 4–5% moisture content (4–6% embryo moisture content) reduced seed lot viability in some but not all cultivars. The results confirm earlier reports that oil palm is not recalcitrant, but neither is it orthodox. Thus, seed storage behaviour in oil palm appears to be intermediate between these categories. Additional results are presented which suggest that the seeds of the royal palm (Oreodoxa regia HBK) may also show intermediate seed storage behaviour.
