Vivipary is characteristic for Rhizophora species. Compliance with ethical standardsThe authors declare that there is no conflict of interest to disclose. In Malaysia, stick thinning is practised. Judging by the greatest volume production of firewood, a 40-year rotation is preferable. The synthesized nanoparticles were characterized for particle size and zeta potential. Background: Cigarette smoke is free radical that causing some pathological conditions such as inflammation, proteolysis, and oxidative stress.In previous studies, mangrove (Rhizophora apiculata) bark extract showed the potential effect as an antioxidant. Derris trifoliata Loureiro can also be a serious strangling weed. Rhizophora apiculata is called ‘bakhaw lalaki,’ in the Philippines, "Thakafathi ތަކަފަތި" in the Maldives, 'Đước' in Vietnam, Garjan in India, as well as other vernacular names. (Editor): Flora Malesiana Series I, Vol. The timber is suitable for making furniture. It occurs throughout the Malesian region and reaches southwards to the Tropic of Capricorn in Queensland, and eastwards as far as New Caledonia and Ponape (Micronesia). Propagules of Rhizophora spp. In Vietnam, annual wood production is about 60 000 t.

Felling of R. apiculata for poles is essentially a thinning operation in which straight pole-sized individuals are cut. Mangrove vegetation. FTIR spectrum of different solvent extracts. Recently, they have also been extensively harvested for woodchips or converted for agricultural and aquacultural purposes. Growth rings and parenchyma are indistinct. NIH Tomlinson, P.B., 1986. Role of Acrostichum species in natural regeneration of Rhizophora species in Malaysia. 447 pp. Planting programmes often coincide with the fruiting season. If cut at least 20 cm above the stilt roots, regeneration is without problems. Wood anatomy of Rhizophoraceae. For biomass calculation, tree height and diameter were measured in plot of 10m x 10m in compartment 18, 31, 71, 74 and 67. R. stylosa has broadly elliptical leaf blades, up to 12 cm × 7 cm, flowers with styles 4-6 mm long and the hypocotyl up to 30 cm long. Hypocotyl cylindrical to club-shaped, up to 40 cm × 1.2 cm before falling, often slightly curved, more or less blunt, smooth and shining, green tinged with red. Total aboveground dry matter has been estimated to be 160-190 t/ha in 15-year-old stands in Thailand and 257 t/ha in a 28-year-old stand in Peninsular Malaysia. have been reported to be the major pests of newly planted propagules. The ferns Acrostichum aureum L. and A. speciosum Willd. It is killed by frost and by extended periods of near-freezing temperatures. Minimum diameter for charcoal production varies from 20.5 cm in Sabah to 4 cm in Vietnam. In large concessions of 2000-4000 ha for wood chipping in Sabah, a diameter limit of 10.2 cm is used, provided that 100 seed trees per ha are left. Leiden Botanical Series 3: 20-75. Eventually, the seedling falls from the fruit, floats with the high tide and establishes if it reaches a suitable site. doi: 10.1371/journal.pone.0236319. In Peninsular Malaysia it takes 35 years for R. apiculata to reach a stem diameter of 19 cm at breast height. 2012 Sep 6;17(9):10675-82. doi: 10.3390/molecules170910675. It is unlikely that any substantial germplasm collections of R. apiculata are being maintained. Keywords: USA.gov. Further, antimicrobial and minimal inhibitory activities of different solvent extracts were assessed against human clinical pathogenic bacteria, and the results showed that butanol and methanol extract has potential antimicrobial activity. Poles are used for piling and construction purposes, and as fishing stakes. PubMed:Growth of a mangrove (Rhizophora apiculata) seedlings as influenced by GA3, light and salinity. Rhizophora apiculata. R. apiculata is the most common mangrove species. In the absence of hurricanes and chain saws, individual trees may reach 40m or more. The main agroforestry uses from this species are soil stabilization, coastal protection, wildlife/marine habitat for marine fauna and also as timber products which are fuelwood, charcoal, dyes, and traditional medicines [7];[8]. Large areas of formerly productive Rhizophora stands have been made unproductive in this way. The sapwood is light yellow, 3-5 cm thick, and very distinct from the heartwood which is reddish-brown and darkens with age.  |  Description. Rhizophora apiculata Bl. After extraction of the tannins, the ash mainly consists of calcium carbonate (70%) and lime (18%) and can be used as fertilizer. According to [6], Rhizophora apiculata is a species of plant in the Rhizophoraceae family. Forest Ecology and Management 17: 211-230. This study assessed the Mangrove-based Rhizophora apiculata was used to synthesize silver nanoparticles. PubMed:Antiviral properties of a mangrove plant, Rhizophora apiculata Blume, against human immunodeficiency virus. J. Arnold Arbor. & Chan, H.T., 1986. In Sri Lanka, Cerebera manghas is used in making masks for many traditional cultural activities. Burma (Myanmar): pyoo. This site needs JavaScript to work properly. The best way to regenerate a mangrove stand at the least cost is to encourage reproduction in the period before the final harvest by thinning and by minimizing damage to young plants during harvesting. A stand of R. apiculata in southern Thailand had an annual leaf production of 7 t/ha and 20 t/ha of wood. Flowers are self-compatible and usually wind-pollinated.  |  Main agroforestry usesSoil stabilization, coastal protection, wildlife/marine habitat for marine fauna. Tannin obtained from the barks of Blume was further separated into condensed and hydrolysable tannins. Growth and water use of the mangroves. R. apiculata is the preferred species in replanting programmes in most mangrove regions in South-East Asia.  |  & Muktar, A., 1987. Rhizophora apiculata and Acrostichum aureum are a common mangrove species in Malaysia. Occasionally, bagworms and larvae of the moth Strelote lipara cause localized defoliation of trees and seedlings. Rhizophora apiculata has been exported from the Philippines to various parts of the world for utilization in the textile industry and extracts of stilt roots exhibited mosquito larvicidal activity. Agroforestry Uses: A part of the mangrove swamps, the tree helps to protect inland areas from the effects of the ocean, including stabilizing the shore line and giving protection from strong winds and storms. The botany of mangroves. It grows gregariously in swamps flooded by normal high tide, on deep soft mud of estuaries, often consolidated and sheltered from surf and currents by pioneer species of Avicennia L. and Sonneratia L. R. apiculata avoids hard soils and develops well in per-humid regions where it can form almost pure stands, sometimes in association with Bruguiera spp. Seedlings may retain their viability for several months. A few specimens have been collected with characters intermediate between R. apiculata, R. mucronata and R. stylosa in western Malesia and western New Guinea. Current rotations vary from 15 years (in firewood plantations in Thailand) to 20-30 years, but may be even shorter. YieldsIn Malaysia, the 30-year rotation har- vested yield of green wood has been about 136– 299 mt/ha (61–133 t/ac). In Vitro Antioxidant Activities of Phenols and Oleanolic Acid from Mango Peel and Their Cytotoxic Effect on A549 Cell Line. The stem of R. apiculata is upright and cylindrical in closed forest, but plants develop a straggling or semi-prostrate habit in unfavourable sites. Indonesia: bakau minyak (general), bako (Javanese), babakoan laut (Sundanese), Malaysia: bakau minyak, bakau tandok, bakau akik, Papua New Guinea: abia (Gulf Province), bahkweh (Northern Province), pana (Central Province), Philippines: bakauan (lalaki), uakatan (Tagalog), bakhau (Samar). Average annual increase in diameter over a 30-year period in Matang, Malaysia, was 0.32 cm. Initially, the phenolic and flavonoid content was quantified in solvent extracts, and gallic acid and rutin were used as a control, respectively. J. Cramer, Vaduz, Liechtenstein. Activity-guided isolation of antioxidant compounds from Rhizophora apiculata. Further, antimicrobial … Damaged young trees are capable of recovering by sprouting from dormant buds and bending upwards to form another erect stem. Rhizophora hypocotyls can be eaten after extraction of the tannin, but this is probably only of importance in times of famine. Initially, the phenolic and flavonoid content was quantified in solvent extracts, and gallic acid and rutin were used as a control, respectively. In vitro antioxidant and anti-cholinesterase activities of Rhizophora mucronata. Large concessions in Indonesia require felling of trees down to a stem diameter of 7 cm in 50 m wide strips interspaced with 20 m undisturbed strips in a proposed 20-year rotation. Thinning is important for good stand development. Main productsTimber, fuelwood, charcoal, dyes, and traditional medicine. Thailand has prescribed the maintainance of a 10 m uncut strip along waterways to reduce the effects of waves and currents on regeneration. Growth and water use of the mangroves Rhizophora apiculata and R. stylosa in response to salinity and humidity under ambient and elevated concentrations of atmospheric CO 2. GC-MS analysis, antimicrobial, antioxidant, antilipoxygenase and cytotoxic activities of Jacaranda mimosifolia methanol leaf extracts and fractions. Felled trees are bucked into billets of about 1 m long, and sometimes debarked before they are transported out of the swamp forest. In South-East Asia 3 Rhizophora species occur: R. apiculata, R. mucronata Poiret and R. stylosa Griffith. Leaves decussate, rosette-like at the end of twigs; stipules lanceolate, 4-8 cm long, conspicuous, caducous; petiole 1.5-3 cm long, reddish; blade entire, elliptical-oblong to sublanceolate, 7-18 cm × 3-8 cm, leathery, green and shiny, apex acute to apiculate, base cuneate, veins distinct above, obscure beneath, glabrous with minute, scattered black corky warts on the lower surface, visible on older or dried leaves.
