Summary<\/span><\/span><\/h2>\n

Xanthocyparis vietnamensis<\/span><\/em> Farjon & Hiep is the only tree species of Xanthocyparis<\/em> genus (Cuppressaceae) which occurs on limestone mountains with poor natural regeneration. Cutting propagation of the species is necessary for genetic conservation. Experiments of cutting propagation show that the species is easy to propagate by cuttings. Cuttings taken from mature trees without treatment gave a high rooting percentage (83.3%). Among five chemicals applied, four chemicals (RA, IBA, IAA, ABT1) gave higher rooting percentages by up to 16.7% as compared to the control. IBA and ABT1 gave the highest results. Some chemical treatment doses gave better root systems than the control.<\/span><\/p>\n

SUMMARY<\/span><\/strong><\/p>\n

Investigation results from Phu Yen and Binh Dinh provinces showed that Ailanthus triphysa<\/em> is frequently distributed on gray brown soil, which developed from granite. The texture is light (light loam and sandy soil). Soil is acidic, with a poor nutrient level. The tree density tends to reduce if the hight above sea level increases, and it is mostly concentrated under 300m. A. triphysa<\/em> is found in many secondary forests, roadsides, the edge of forests, milpa, or along streamsides. With poor regeneration, the density decrease if the canopy of forest increases. Flowering in March and April, ripe fruit in June and July. Additionally, they flower in other months, but the quantity of fruit is poor. Fruits are wingede, and are distributed via wind so it is essential to harvest them before they fall.<\/span><\/p>\n

SUMMARY<\/span><\/strong><\/p>\n

Castanopsis piriformis<\/span><\/em> is a native and multi-purpose species. Its wood is used for making furniture, and fruit is used for food as it has a high nutritional value. Fruit morphology is highly related to seed quality. Research on the relationship between fruit morphology and seed quality of Castanopsis piriformis<\/em> is necessary to identify suitable times for harvesting seed, which will result in high quality seedlings. Experiments were carried out with three fruit morphologies as green color (unripe); brown color (ripe); and brown color with cracked fruit cover. Nursery qualities were evaluated based on seed dimension; seed uniformity; seed weight; germination rate; and relationship between fruit weight, seed weight and kernel. The result showed that fruit of Castanopsis piriformis<\/em> should be harvested when it is ripe (brown color), which will result in high quality for nursery. At the moment, seed dimension 22,9 – 24,7 mm, seed thickness 17,1 – 17,9 mm, seed uniformity 84,1\u00a0 – 87,1 %, seed weight 4.334,6 – 4.537,4 g and germination rate 78%.<\/span><\/p>\n

SUMMARY\u00a0<\/span><\/strong><\/p>\n

This research aims to assess the ability to create agar-wood in Aquilaria crassna<\/em> using different chemicals in production, and initially evaluating the market for agar-wood essential oil consumption. The survey results showed that currently Vietnam has quite a number of chemicals used for agar-wood formation. Through the analysis of the wood samples affected by various chemicals, the oil content tends to increase where the tree is affected by chemicals, and within a tree, the oil content is greater at the place where it is affected by the chemical. The market for agar-wood essential oil is large across the world, but the domestic units for producing and trading the essential oil are not able to access those markets, so that they have to trade through a middle man, and they have to accept lower prices. The domestic market is not so clear.\u00a0\u00a0<\/span>\u00a0<\/span><\/strong><\/p>\n

SUMMARY<\/span><\/strong><\/p>\n

Ethanol and some organic solvent extracts from the seed kernels of Azadirachta excelsa<\/em> Jacob were used for the evaluation of antitermitic activity based on wood preservation standards (using Abbot\u2019s equations) and testing on petri dishes\u00a0 in the laboratory. The results of testing on termites calculated by Abbot\u2019s equations indicate very good effects with most termiticide formulas selected. However, the smaller the mass of seed kernel used, the larger the numbers of wood samples damaged and wood samples are destroyed not only on sides but also at depth. The testing on petri dish showed that seed kernels contain chemical compounds which have antifeedant activity. Additionally, there are also some compounds which were toxic to termites in this experiment. The primary results add scientific information and improve research for a better understanding of toxicity mechanisms of compounds extracted from seed kernels of\u00a0 Azadirachta excelsa<\/em> Jacob\u00a0\u00a0\u00a0 <\/span>\u00a0<\/span><\/strong><\/p>\n

Summary<\/span><\/strong><\/p>\n

Wood used in ship building is often extensively damaged by Bankia<\/em>. The results show that materials including Vatica odorata<\/em> Spp. Brevipetiolata phmh<\/em>, Hopea odorata<\/em> Roxb, and Dipterocarpus costatus<\/em> Gaert.f are destroyed by Bankia<\/em> in a short period of time, and all testing samples were damaged in 12 months. Eucalyptus camaldulensis<\/em> is also damaged by Bankia <\/em>in six months. The ability of penetration of preservative XM5<\/sub> by use of pressure of vacuum and hot-cold processes was determined ro four species of wood. Testing samples were penetrated solutions of XM5<\/sub> in four concentrations (10, 15, 20, 25%) and evaluated over a period of three years. The results showed that all wood samples might limit destruction by Bankia.<\/em> If penetration of XM5<\/sub> is more than 6 Kg\/m3<\/sup>, the resistance to Bankia<\/em> of wood is good. The results of this research are scientific evidence for building technical options to protect wood without damage by Bankia.<\/em><\/span><\/p>\n

SUMMARY<\/span><\/strong><\/p>\n

E. urophylla<\/span><\/em> timber is a potential wood resource but its utilization as a sawn timber material for furniture making is limited. Although E. urophylla <\/em>woods physical and mechanical properties are similar to Acacia species and some other natural forest species the utilization of E. urophylla<\/em> timber for furniture making is limited because of the deformation of E. urophylla<\/em> wood during processing: including end splitting; spring; bow; and shrinkage. To reduce the deformation and defects of E. urophylla<\/em> timber products, the solution of wood moisture control was applied in this research.<\/span>The changing of wood moisture was implemented by controlling environmental humidity in each step of processing, such as: logging; logs storing; sawing; air drying; and kiln drying. The product quality and wood use effectiveness were improved significantly. E. uropyilla<\/em> wood is stable with finishing material and good gluing. Furniture products made of E. urophylla<\/em> wood have nice grain and coloring.<\/span><\/p>\n

Summary<\/span><\/strong><\/p>\n

Melaleuca cajuputi<\/span><\/em> saw timber is potential material in the Mekong Delta. However, this wood has not been utilized as a material for the wood product processing industry, with most of the Melaleuca cajuputi<\/em> saw logs being made into \u201ccu\u201d (a type of pole is used for building), fuel, coal, etc. In recent years,\u00a0 Melaleuca cajuputi<\/em> wood has been exported to other countries to make paper.\u00a0\u00a0 The rate of Melaleuca cajuputi<\/em> wood which is utilized as sawn timber was quite low in comparison with the rate of exploitation each year. To enhance the\u00a0 Melaleuca cajuputi <\/em>wood value, research on diversifying industrial products made from\u00a0 Melaleuca cajuputi <\/em>wood such as Particle board, MDF, Furniture, Laminated board.etc. are encouraging.<\/span>After kiln drying,\u00a0 Melaleuca cajuputi<\/em> saw timber is distorted, and the deformation rate is quite high, so superfluousness of kiln drying process (SKDP) is high.\u00a0 Therefor determining the SKDP of\u00a0 Melaleuca cajuputi<\/em> sawn timber is necessary for calculating sawn timber processes before drying.<\/span>The results of determining SKDP of\u00a0 Melaleuca cajuputi<\/em> sawn timber show that according to different saw methods\u00a0 the Melaleuca cajuputi<\/em> saw timber was highlydeformed (more than 10%). In Comparison with other\u00a0 wood plantation species, SKDP of\u00a0 Melaleuca cajuputi<\/em> sawn timber was twice as high as that of Acacia sawn timber.<\/span><\/p>\n

Summary<\/span><\/strong><\/p>\n

Evaluation results on forestry encouragement in Daklak province revealed that despite having achieved good results, forest cover across the whole province is 47.2% but by many different causes the area of forests in Daklac continue to be declining in quality.\u00a0 Natural forests continue to be invaded, plantation growth is fast but slow growth of the production of improved seeds Forest allocation, delays in forest rent implementation, and the renewal of state-owned forestry farms still encounters obstacles. Although the situation is strengthened, forest exploitation by illegal deforestation is serious, there is poor coordination between agencies in forest protection laws and there has been slow development of regular ecological tourist activities. The processing industry is relatively developed, with an export turnover reaching 6 to 7.5 million per year, and with 438 forest product processing facilities. Forestry extension work is not considered important. From these situation studies, six solutions to develop forestry in Daklak are recommended. Besides specific solutions, urgent and immediate proposals to redress and implement effective protection and development of forests in Daklak over the future have been given.<\/span><\/p>\n
