Gum or resin: The species is tapped for its resin (traded as Manila copal). In the Philippines recent research has shown its importance for the national economy. Root suckers can be produced several times from potted seedlings and are considered to be the most successful material for vegetative propagation. Plant the seedling at proper depth. It is still used in road-marking reflector paints. This phenomenon has not yet been explained. A total of 81 individuals were arrested by the authorities in a three-day Synchronized Enhanced Managing Police Operations... No demolition of illegal structures until January. under taungya systems, with food crops between them for 1-2 years, a shade plant, e.g. Agathis alba (Rumph. Male inflorescences consisting of pollen cones in or slightly above the leaf axils or seldom terminal, sessile or nearly so, more or less cylindrical, subtended by several pairs of scales forming a basal cupule, made up of numerous small spirally placed and narrowly stalked microsporophylls having a more or less peltate head bearing up to 12 pollen sacs. Only trees at least 40 cm in diameter at breast height should be tapped. A. borneensis has 4000 seeds/kg and A. dammara 4800-5200 seeds/kg. Contents. pieces of bark, soil), and the colour and size of the resin particles. In Malaya, the resin is used as a liniment. Within the … Copal from Leguminosae has also been exported from Africa (from Copaifera spp., Hymenaea verrucosa Gaertn. Thermal processing at 315-360°C for 2 hours makes the resin soluble in oils for application in oil varnishes. This resin used to be very important as a raw material for varnish as it has good storing quality, and the varnish film is very lustrous, elastic, and has good weathering properties. Moreover, it is very difficult and thus expensive to collect seed from these large trees, as their cones disintegrate and it is not recommended to collect fallen seeds. https://uses.plantnet-project.org/e/index.php?title=Agathis_(PROSEA_Exudates)&oldid=330598, Creative Commons Attribution-ShareAlike License, Indonesia: damar (Java), damar sigi (Sumatra), damar bindang (Kalimantan), Malaysia: damar minyak (general), mengilan (Sabah), bindang (Sarawak), Philippines: almaciga (general), bidiangao (Negros), bagtik (Palawan), Indonesia: bembueng (south-eastern Kalimantan), damar pilau (Dayak, Kalimantan), hedje (Sumatra). Gums, resins and latexes of plant origin. Cookies help us deliver our services. The solubility in 95% ethanol is an important grade criterion. The resin is soluble in ethanol and acetone, but partly soluble in petrol, benzene, terpuntine, and chloroform. Naturally established seedlings in plantations can also be used as planting stock. Darker specimens of resin gave higher acid and saponification numbers than did lighter-coloured ones. In plantation-making, maintain a two-meter distance between seedlings if they are planted in a row of a three-meter distance from one strip to the next strip. Agathis celebica (Koord.) Agathis is the most tropical genus of the Coniferae and the number of species varies with the species concept: the narrow concept recognizes 21 species, the wider concept only 13. Free and Open Access to Biodiversity Data. Whitmore, T.C., 1980. It has no buttress but with big, swollen, superficial roots. Medium to very large monoecious but strongly dichogamous trees of up to 65 m tall; bole straight and cylindrical, up to 200(-400) cm in diameter, without buttresses but often with swollen superficial roots at base; bark surface at first quite smooth and light grey to reddish-brown, peeling with large, irregular roundish thick flakes leaving a pitted somewhat rough black or purplish-brown to fawn surface with an orange hue on larger trees; crown monopodial, usually eventually sympodial, that of young trees conical, but globular or umbrella-shaped in older ones, large branches often irregularly upturned. Based on the data gathered from the Department of Environment and Natural Resources (DE NR, 2017), Al maciga (Agathis philippinensis) i s an ancient plant and it is widely used in the Philippines as a development crop. In Palawan, for example, indigenous communities used to sell forest honey and resin from the Almaciga tree (Agathis philippinensis) to traders from Cebu and Manila, but this has come to a halt, because the traders are no longer allowed to travel. Ex situ conservation is important for A. dammara, which is planted on a fairly large scale in Java. Traditionally it has been used as a fuel for camp fires, as a torch, as a waterproofing on boats, as a medicine, the smoke from the burning resin is used as a black dye and for tatooing. Berichten van de Afdeling Tropische Producten van het Koninklijk Instituut voor de Tropen No 267. (Editors): Plant resources of South-East Asia No 5(1). Almaciga definition is - a tall Philippine timber tree (Agathis philippinensis) yielding a hard resin. Esterification with glycerol neutralizes the natural acidity and renders the resin more soluble in drying oils for its use in paints and varnishes. pp. Fill the hole with top or garden soil and press soil firmly around the base of the seedling. The cones become massive and woody at maturity, with viable seeds forming only at the center of the cone. Be sure to always use a sharp-bladed knife to cut the bark to minimize damaging the cambium. The species is Diameter increment can easily exceed 1 cm annually. BAYOMBONG, Nueva Vizcaya: The Almaciga (Agathis philippinensis) tree, one of the Philippines’ endangered forest trees found in the Sierra Madre mountains, is rapidly vanishing, according to the Southeast Asian Regional Center for Graduate Study and Research in Agriculture (Searca). Place mulch around the base of the seedling (maintaining the 50-centimeter radius and using cut grass, leaves, and other suitable materials as mulch base). "Melengket" dissolves easily in ethanol, whereas "loba" dissolves only partly. When A. labillardieri is planted in open terrain, e.g. Generally, Agathis is best adapted to grow in rocky soil. rattan (strong stems used to make baskets and other furniture), but mostly the resin from the Agathis philippinensis tree (local name: Almaciga) which accounts for 80% of their income (CS 2014). When cutting, great care must be taken to avoid damaging the cambium, as the resin ducts are only found in the bark. Gonzales, E.V. Agathis philippinensis (in Tagalog: Almasiga or Dayungon) is a species of large Agathis tree native to the Philippines, Sulawesi and Halmahera, where it occurs in upland tropical rainforest at 450-2,200 m altitude, rarely as low as 250 m in northern Luzon..
