Abstract

Canarium odontophyllum is a rare tropical fruit that is primarily propagated by seeds.
However, there is little information regarding its seed handling and germination. As
low seed moisture content (MC), generally that below 10%, is the key determinant to
successful seed storage while avoiding microbial damage, the objective of this study
was, hence, set to investigate C. odontophyllum’s seed germination as affected by
desiccation using drying beads (DBs) at room temperature or convection oven at
40C to varying seed MCs, from its initial MC of above 20% down to that below 10%.
It was found that the seeds tolerated fast dehydration within 24h at room temperature
using DBs. They retained 90% germination despite seed MC was reduced to below
10%. Desiccation tolerance with DBs was, however, found only with seeds extracted
from fresh fruits. As the fruits started rotting with wrinkled appearance and fungi on
the pericarp from four days after harvest onwards, the seeds extracted from them died
at MC of below 15%. A slower seed drying method using convection oven at higher
temperature of 40C, on the other hand, took 72h to bring the seed MC down to
