Dryobalanops (Dipterocarpaceae) Malaysia
Page : 1ReplyNew topic
Along the road of MARDI in Seri Kembangan (Selangor) there is a bunch of large Dryobalanops aromatica (Dipterocarpaceae). Camphor extracted from Dryobalanops aromatica was exported in medaeval times to the Middle East where it has been said it was worth its weight in gold as a base for incense. Iban girls formely used camphor resin in a similar way, melting the camphor then infusing it with other scents; it was then used as a solid perfume and hidden in their pillows (Ashton P.S. Tree Flora of Sabah and SarawakVol. 4 page 6).
Currently the species is classified as “critically endangered” by the IUCN http://www.iucnredlist.org/details/33932/0
Location: http://pericopsis.org/trees/engoutnam.php?tid=6337
Seeds collected along the road were chosen as slightly open nuts with root tip just visible. Plants were raised at INTROP nursery on the campus of UPM (Universiti Putra Malaysia). Nuts were buried on half of their thickness in small polybags using a topsoil/sand/chicken manure mixture. The polybags were then placed under à 50% shaded cover. 80% of the seeds germinated and 70% of them gave nice seedlings.
After a year the seedlings were transplanted in 2 Liter polybags and transferred under full sunlight. This induced some stress and seedlings needed to be watered daily due to the limited size of the polybags. To my opinion would be ideal if such seedling could be planted outside as soon as possible letting the root system developing freely. Directly planting the nut outside should be possible if shading and watering could be provided during a few months.
In contrary to other dipterocarpaceae such as Shorea leprosula (meranti), Dryobananops aromatica respond very well to NPK granules fertilization. Despite planting the seedlings in non forest soil and adding fertilizer after a month roots showed well developed ectomycorrhizas.
Finally the 3 trees were planted two years after during the "Tree for Life" event organized by MBSA in Shah Alam.

The saplings did not develop fast at during the 2 years at UPM nursery because the small size of the polybags. It was very hot at planting and it didn't rain during the following week. I am eager to return to Shah Alam to check if the tree have survived. I will keep you informed.
Trees just after transplantation (21 June 2014)
One month later one tree has only two leaves left and the tip broken.
The two other trees are OK. One is slightly less green with many leaves eaten by insects. New leaves are absent. This is probably linked to the transplantation stress in an area that is windy and exposed to full sun. If the trees survive it will be interesting to see how they adapt to a heavy soil with a high water table. Indeed, D. aromatica has been reported to grow naturally on sandstone soils and D. lanceolata on clay and shale soils.
