The 1000-seed weight was about 0.3 g, and the germination rate was about 100. In some years the seeds do not germinate.
Production in the use of asexual propagation, Rubber fig cuttings in the spring after a steady rise in temperature, pruning young trees within 5 years of the young twig, with terminal cutting, the old branch is not easy to survive. Cut more milk, cut the branches, inserted in water for a few hours, wash the incision, and then inserted into the wet sand bed. Keep the light sparsely, spray moisture, about 25 days to the roots, about 2 months to the basin, the year as a small pot for viewing.
The high pressure propagation was carried out on the young shoots of 1 or 2 years. Wash the cut milk or wrapped with grass ash, ring peeled wrapped mud about half a month, rubber fig tree root cut off the pot.
