PLANTING STOCK PRODUCTION OF DIPTEROCARPS IN MALAYSIA*
H. Aminah1
Species-rich dipterocarp forest types comprise 88,9% of the Malaysian tropical
rainforest. Dipterocarp species are among the most commercially important timber species in south-east
Asia, but seed supply of dipterocarps is irregular and the viability is short. The seeds are incapable
of withstanding desiccation, resulting in difficulty of prolonged storage by conventional methods.
The nursery of the Forest Research Institute of Malaysia (FRIM) has successfully developed
propagation techniques for production of planting stock of the species. The techniques developed include
propagation by seeds, wildings and vegetative propagation by stem cuttings. The success in rooting
stem cuttings from juvenile materials is a boon to the forestry of Malaysia. Methods of propagating
and handling dipterocarps in the nursery until they reach plantable height are provided in this paper.
