In summary, increasing duration of heat-treatment to break dormancy in the commercial oil palm progenies
negatively affected seed germination and also subsequent seedling growth. This study has shown that
heat-treatment duration of 60 days and not 80 days was effective for breaking oil palm seed dormancy and
successful seedling growth. With respect to seed germination, progenies A5240, A5291, A5234, and A5221
were the most outstanding progenies, out of the ten progenies tested. These four progenies can be used for the
genetic selection program for commercial oil palm seed production. The study described here shows that oil
palm seeds germination can be obtained within a short period (60 days) of heat-treatment compared to the
current 80 days application by PAMOL Plantation Ltd. Lobe estate. This shorter duration of heat-treatment,
which results in significant percentage germination could provide considerable solutions to the numerous
demands of oil palm seeds by local farmers and also more profit to the plantation estate.
