Progress in the genetic improvement for some main commercial planting tree species in Vietnam

Fea_UN Food_Figure2

Research Centre for Forest Tree Improvement, FSIV SUMMARY FSIV has a long running program of genetic improvement for some of the principle plantation species to select the best genetic material for high productivity and wood quality for the various wood and non-wood forest products. FSIV has also been developing mass-propagation techniques to assist in the technological transfer of the genetically improved planting material to commercial plantations while maintaining diversified breeding … [Read more...]

Research on the scientific basis for grouping wood species in Vietnam

Do Van Ban Forest Plant Resources Research Division (FPRRD) Forest Science Institute of Vietnam (FSIV) The temporary grouping table for wood species in Vietnam was enforced in 1977 by the Ministry of Forestry as summarizing the grouping table of wood species in Southern Vietnam. For Northern Vietnam, Decree 10-CP of the Vietnamese regime issued in 1964 applies. The temporary wood species grouping table 1977 listed a total of 362 wood species. Since enforcing the temporary grouping … [Read more...]

Determination some physical and mechanical properties and usability of edrela odorata wood

Do Van Ban Forest Plant Resources Research Division (FPRRD) Forest Science Institute of Vietnam (FSIV)  The tree species Cedrela odorata L. belongs to the family Meliaceae, and is distributed widely in  Latin America. In 1986 and 1989 Nguyen Huu Loc, Pham Quang Minh and Do Xuan Quy brought some seeds from Mexico and seeded them in places such as Huu Lung (Lang Son Province) and Xuan Mai (Hanoi City). Ten years after seeding, some seedlings have become big trees with … [Read more...]

Wood properties of some commercial tree species for the central North region of Vietnam

Le Thu Hien, Do Van ban, Le Qui Thang  Forest Plant Resources Research Division            There are 13 species in the list of popular commercial tree species for planting in the Central North of Vietnam, of which wood properties of 8 species have been researched. The methodology complied with the national stardards of Vietnam, from TCVN 358-70 to TCVN 370-70. Styrax tonkinensis (Pierre) Craib ex Hardw: Wood density was … [Read more...]

Applying tablet-Shaped mixed biofertilizer (MF1) to pine and eucalýpt in the nusery

Pham Quang Thu, Tran Thanh Trang, Nguyen Hoai Thu,Nguyen Manh Ha, Dang Nhu Quynh Forest Science Institute of Vietnam  With the aim of producing high-quality seedlings of eucalypt and pine species biofertilizer, including soil live-in microorganisms, has been produced and applied to seedlings in the nursery. In forest production phosphate fertilizer is usually applied to soil in order to improve the productivity of trees. However, after a while the soluble phosphate … [Read more...]

Anthracnose disease of Manglietia conifera Dandy seedlings in nursery

Pham Quang Thu Forest Science Institute of Vietnam  Manglietia connifera Dandy young seedlings in the nursery are often infected with anthracnose disease, with a very high disease incidence in low-light and too high soil moisture condition. The pathogen is determined by the fungus Colletotrichum gloeosporioides (Penz.) Sacc (anamorphic stage). Sexual stages (telemorph) of the fungus are Glomerella cingulata (Stoneman) Spald. & H. Schrenk being found on diseased leaves. … [Read more...]

Research on forest structure of Schima superba Gardn. Et Champ in central highlands

Vo Dai Hai, Nguyen Hoang Tiep Forest Science Institute of Vietnam             Schima superba Gardn. Et Champ is one of the large-sized, native, multi-purpose trees, often encountered in evergreen-broad-leaved forests that have undergone exploitation in provinces of the Central Highlands of Vietnam. This tree has been over used while our knowledge about it is rather little thus lacking in scientific bases for sustainable … [Read more...]

Criteria for very poor natural forests to be converted into economic sufficient forests

Tran Van Con Forest Science Institute of Vietnam  Much tropical primary forest cover decline is accompanied by an increase in the area of secondary forests (heavily degraded forest) in Vietnam. Based on the method of establishment of secondary degraded forest, four major categories were identified in Viet Nam: (1) post-extraction secondary forests, (2) swidden fallow secondary forests; (3) post-fire secondary forests; and (4) rehabilitated secondary forest after failed … [Read more...]

Research results of evergreen broad leaved and semi-Decidouous forests in Vietnam

Tran Van Con Forest Science Institute of Vietnam  Natural tropical forests are characterized by an immense diversity of plant and animal species, a complex structure and architecture of the vegetation and a mosaic of vegetation development phases. They are never homogeneous, neither in structure nor in architecture, even where there has been no filling or other artificial impacts. Gaps, varying in size and frequency, and here and there “climber tangles” or thickets of … [Read more...]
