The difficulty of getting good quality planting stocks has often been quoted as the limiting factor for the success of using dipterocarp species in artificial regeneration. Studies in FRIM have shown that flowering in some dipterocarp trees can be more frequent than previously reported. Although the seeds are recalcitrant, through proper treatment some of them are able to retain viability for a few months. A high proportion of freshly collected seeds are able to germinate, producing a large number of seedlings. Overgrown seedlings may be rejuvenated by root wrenching and trimming of the shoots. Planting of these treated seedlings in the field showed promising results. Some of the dipterocarp species can also be successfully propagated by vegetative means which will reduce the dependance on seeds for the production of planting stocks
